| SSD1306 driver for use with less RAM |
 Posted: Sat Oct 10, 2015 4:35 am |

Updated October 2018. An optional alternative way of running for PCD chips.
Updated Nov2017 - I've changed the font and bar graph output to be 0-100
Second amendment Dec 2017 Now supports a new #define to operate the SH1106 display as well. Also slightly more efficient
This is an example of a slightly 'different' SSD1306/SH1106 driver, for people working with restricted RAM.
The problem is that these chips do not allow a read, when in serial mode.
Now if (for instance), you set a pixel, on a 'clear' screen, then this is
not a problem. However if you then go to set a second pixel, you need to test
if any other pixel in the same byte is already set. So you need to 'know'
what is on the screen. The solution with the standard driver, is to have a
RAM buffer carrying a 'copy' of the screen, and then you can test the byte
in this, and if another pixel is set, send the whole byte with both pixels
to the display. However if you are trying to drive the screen on a chip
with very limited RAM, you don't have the space for such a buffer....
This driver allows some operations on the display, using varying amounts of
RAM.
It is in two parts. The first is a 'text' driver for the screen, which
uses a 6*8 font which is designed to be clear even at the small sizes on
the 0.96" displays. It gives you 21*8 text on the screen, with the ability
to also use the font 'double size' to give 10*4 text. It includes
thirteen extra characters in the font, which allow a 'bar graph' to be drawn
using 9 characters, and giving 0-100 (actually 101). for a empty bar to a
full bar. Again the double size mode can be used, to give a bar nearly the
width of the screen.
Key thing 'for' these screens, is they work in a wide range of light
conditions and at low temperatures where LCD's give problems - and they
are cheap!...
The driver is for I2C mode.
Look at the comments in the driver and example, to see how it works:
ssd1306.h
| Code: |
/*
Now the big limitation.....
In serial modes (SPI/I2C), this chip provides no ability to read back it's RAM.
So we have a problem. If we want to write a line across the screen, and leave
another line that is already there 'undestroyed' where they cross, how can we
'know' the other line is there?. Basically the host chip needs to have a copy
of the display memory so it can hold a copy of any graphics and know what is
going on. Problem is that this is just not possible, on a PIC with limited RAM.
So this driver works by overwriting for all text writes....
But see further down for the 'exception' to this.
*/
//It is most efficiently used by preparing the whole line of text first
//and then sending this - it then uses a 'burst' transmission, to give very
//fast updates. It does offer a 'putc' though, but this is slower.
//It does not properly handle wrapping at the end of the line.
//The putc function adds support for \n, \r, and \f.
//Functions:
// OLED_CLS(); //clears the screen
// OLED_gotoxy(x, y); //goto column/row 0-20 for the column
// //0-7 for the row
// OLED_text(*text, number);
// //This sends 'number' bytes from the array
// //pointed to by 'text', to the display
// OLED_putc(c); //sends 'c' to the display. Beware though
// //if you go beyond the end of the line
// //- you'll get partial characters....
// OLED_textbar(width); //Displays a bargraph. With width=50
// //you get a 50:50 display of bar/void.
//Two global variables affect how things are displayed.
// size=NORMAL;
// size=LARGE; //switches between showing 21*8 & 10*4
// size=DOUBLE_HEIGHT //Gives 21*4 - great for the bargraph
// set=TRUE; //default. Pixels are 'set' when written, so
// //turn on.
// set=FALSE; //all write functions now invert.
//The CLS will now set the screen white. Text characters print in black
//Then the second part of the driver is a 'window' driver. With this you can
//define a small graphic 'window', and draw things into this. This can then be
//rapidly copied to the display. So you could (for instance), plot a tiny graph,
//end then draw this on the display.
//The window must be a multiple of 8 pixels high, and can only be placed
//at a 'text' location, so you can't put it (say) 12 pixels down the screen,
//but only 8, 16, 24 etc..
//The size of the window determines how much RAM is used. So a 64*16 window
//uses 128 bytes of RAM (64*16/8).
//Neat thing is though, that you can draw an image on the window, put this on
//the screen, and then draw a second image, and put this somewhere else,
//without using any more memory. At the moment, I have only implemented two
//functions to draw to this window.
//If you don't want the graphic ability, if you #define TEXT_ONLY, then only
//the text mode driver will be loaded.
//With the graphic driver being used, the following extra functions are
//available:
// clear_window(); //clears all pixels 'black' (if set==TRUE), or white.
// set_pixel(x, y); //sets a pixel at x,y in the window.
// //x=0 to WINDOW_WIDTH-1 (left to right)
// //y=0 to WINDOW_HEIGHT-1 (top to bottom)
// line(x1, y1, x2, y2); //draws a line from x1,y1 to x2, y2
// rect(x1, y1, x2, y2); //draws a rectangle
// circle(x, y, radius, fill); //draws a circle
// //This draws a circle of radius 'radius' centred at x,y. If 'fill' is
// //true this is filled....
//
// draw_window(x, int8 y); //This draws the window onto the screen at
// //x=0 to 128, y=0 to 7.
//What you do is simply draw the shape you want into the window, and then
//this can be drawn onto the screen.
//I have not included font drawing, since this takes a lot more space....
//'set' again controls whether a pen, or eraser is used. So (for example), if you
//wanted a 'thick' circle, you could either draw several using the pen,
//without 'fill' enabled, or could draw one with fill, then change set to
//false, and draw a smaller one, to give a thick ring.

Now an example program using the driver in 'text mode' only:
mainssdtext.c

#fuses INTRC_IO, PLLEN, NOXINST, NOMCLR, NOLVP, STVREN, PCLKEN, NOFCMEN
#fuses NOIESO, NOPUT, BORV22, NODEBUG, NOPROTECT, NOWDT, WDT512
#fuses HFOFST, NOCPD, NOCPB, NOWRTD, NOWRTC, NOWRTB
#USE DELAY(INTERNAL=32MHz)
#USE I2C(I2C1, MASTER, FAST=400000, FORCE_HW)

#define TEXT_ONLY //If this is defined, gives a smaller text driver only
#define SSDADDR 0x78 //address for the chip - usually 0x7C or 0x78.
#include <string.h>
#include "ssd1306.h" //The OLED driver
void main()
{
int8 ctr;
char text[9]; //temporary text buffer
delay_ms(250); //OLED takes time to wake
//now try to initialise OLED
OLED_commands(init_sequence,sizeof(init_sequence)); //initialise the OLED
//Now try some text
set=TRUE;
size=NORMAL;
OLED_CLS(); //clear the physical screen
OLED_gotoxy(0,0);
strcpy(text,"Hello");
OLED_text(text,strlen(text)); //This is the fastest way to write text
delay_ms(2000); //pause for two seconds
OLED_gotoxy(0,4);
size=LARGE;
OLED_text(text,strlen(text)); //try some large text
delay_ms(2000);
//Now the printf mode
size=LARGE;
//now testing putc
printf(OLED_putc,"\f12345\n\r67890\n\r");
//Note how the line feed moves down by the large line when in
//large mode
delay_ms(2000);
//Now printf in normal mode to the same screen
size=NORMAL;
printf(OLED_putc,"ABCDEFGHI");
delay_ms(2000); //delay again so you can see what it has done
//Now mixed size with a bar graph
size=LARGE;
printf(OLED_putc,"\fV=");
for (ctr=0;ctr<101;ctr++)
{
size=NORMAL;
OLED_gotoxy(4,1);
printf(OLED_putc,"%3d ",ctr);
OLED_gotoxy(1,3);
size=LARGE;
OLED_textbar(ctr);
delay_ms(250); //So you can see what is displayed!...
}
while(TRUE)
; //and stop
}
|
On the chip used here, this uses 37% ROM (about 3K), and 23% RAM (58 bytes).
Now a larger demo, using the graphics mode
| Code: |
//same processor header
//display dimensions - the physical LCD
#define S_LCDWIDTH 128
#define S_LCDHEIGHT 64
//#define TEXT_ONLY //REM this out
//Size of graphics 'window' see the graphics section for explanation
#define WINDOW_WIDTH 64
#define WINDOW_HEIGHT 16 //sizes of the graphic window in pixels
//height must be a multiple of 8. //these must now be defined
#define SSDADDR 0x78 //address for the chip - usually 0x7C or 0x78.
#include <string.h>
#include "ssd1306.h" //The OLED driver
void main()
{
int8 ctr;
char text[9]; //temporary text buffer
//Remember if you want to use this for longer text, you'll need to
//expand the buffer....
delay_ms(250); //OLED takes time to wake
//now try to initialise OLED
OLED_commands(init_sequence,sizeof(init_sequence)); //initialise the OLED
//First try some text
OLED_CLS(); //clear the physical screen
set=TRUE;
clear_window(); //clear the window buffer
OLED_gotoxy(0,0);
strcpy(text,"Hello");
size=NORMAL;
OLED_text(text,strlen(text));
delay_ms(1000);
//now some graphics
line(0,0,64,16); //draw line in window
line(10,10,61,0);//and a second
//now write the window to the screen
draw_window(64,0); //at 64 pixels across and top of screen
delay_ms(1000);
set=FALSE; //inverted drawing
clear_window(); //clear the window to fully set!
line(0,0,60,15);
line(20,10,40,10);
circle(32,8,8,1); //just touch the edge of the window
draw_window(64,4); //put this window half way down screen
delay_ms(1000);
while (TRUE)
; //and stop
}
|
This is significantly larger (uses 192 bytes of RAM - this is the 128 byte
graphic 'window'), and over 5KB ROM. However still fits merrily in the
small chip. If you don't need things like the circle function, removing
these will reduce the ROM size a little.
Hopefully of use to somebody!... 
As a final comment, somebody posted asking for the minimum code to set a pixel on such a display. The following 'main' does this:
| Code: |
void main()
{
int8 temp=1;
delay_ms(250); //OLED takes time to wake
//now try to initialise OLED
OLED_commands(init_sequence,sizeof(init_sequence)); //initialise the OLED
OLED_CLS(); //clear the physical screen
//Now just write a single byte to the start of the RAM
OLED_data(&temp, 1);
while (TRUE)
;
}
|
Now one final thing. Remember this chip is a 3.3v device. Using 3.3v I2c, you need small pull-ups to run this fast (I used 1.2KR).
You can also use size=DOUBLE_HEIGHT; which is very nice for the bargraph.
But I hear you say, it says it can use 5v Vcc. Yes it can, but the core _chip_ is 3.3v. It has it's own regulator on board for the logic, and the logic can run at 3.3v max. Beware not to overdrive it if running off a 5v device....
Have had it going successfully off a 5v device, by setting this to use SMBUS levels (many PIC's support this), and having the pull-ups to 3.3v. Or if you pull-up to 3.3v, and use _software_ I2C, on a port that supports TTL levels it also works OK.
I've updated this to allow some expansions to the font if required. Have changed the master code involved here, and posted some example expansions below. 5th Jan 2018.
Separate update October 2018.
If using PCD, using ROM *, is quite inefficient because of the maths involved in 3 bytes/word, and then the gap. On some chips this also seems to cause issues.
There is an alternative:
| Code: |
#include <your_processor_file>
#device PSV=16
//Then the rest of your processor setup
#define PSV
//Then include the SSD driver fonts etc.
//Then your code.
|
I've modified the driver, so if it sees 'PSV' defined, it changes the pointers from ROM pointers to normal RAM pointers. The PSV option enables a special mode, where the DsPIC's map 32K or their ROM, into the RAM address space, allowing normal RAM pointers to access this.
Has a slight cost, in that only two bytes get packed per instruction word when this is done. However does bring improvements to overall code efficiency.

@Ttelmah
Absolutely brilliant work !!
Works very well.
I have been trying to understand the bar graph routine "OLED_textbar"
but haven't managed to tweak it yet.
I want to have the bar graph display from 0 to 100, not 0 to 102.
Can you mod it for percentage please. |

Just use it, and accept it'll not quite get to the top!...
The reason it goes 0-102, is to save code space. The font characters are 6 dots wide. The 'bar' font characters give a single vertical strip at the left, then two strips, then three up to all six 'on', Then the 'blank character with no vertical bars, and then for the other end a single bar at the right, then one on the left and one on the right, two on the left etc.
So if you draw nine character, you have 54 vertical bars 'possible'. The left strip and right strip are left permanently on to 'delimit' the graph, so you have 52 useable strips. The incoming number is divided by 2 (binary division which implies just one rotation - quick and small), one is added, and the resulting number determines how many bars are turned on. 100, would turn on 51 strips out of the possible 52. |

| ADC readings |
| Posted: Mon Dec 28, 2015 8:31 am |

This copied from a private message sent to me, however posting as a general reply:
| Quote: |
hi Ttelmah;
i need your help about i2c ssd1306,
your code work properly good, but i cant use adc conversation,
i tried all combinations of edit of code.. Confused
can you send me any example of work with adc and ssd1306
i use 18f4550 (but this is not important)
actually i tried other driver(high sized ram capability) other forum sites.
i didnt work too.
i tried nokia 3310 and nokia1100 lcd with adc. there is no problem with this display.
pls say to me where is my wrong ??
im waiting your ASAP reply,
thanks for now...

It sounds rather as if you are approaching things the wrong way.
You should not be modifying the code.
The place to start is with things in sections.
First ignore the 'ADC readings'. Just get the hardware working with the display.
Do something like the basic demo program posted here. You have not said what PIC you are using, what clock rate etc..
Movement should be:
1) Get the PIC working. Can you flash an LED, and get it to flash at the correct rate (when you program 1 second, does it flash in one second)?.
2) Then get the display working. the basic demo program here, with your fuses and clock (and the pin numbers your PIC is using).
3) Then put this to one side, with the display code 'unchanged', and run a basic program loop to read the ADC. Use this code (or any other), as a _library_. Don't change this, but call it from your code. So something like:
| Code: |
//This part to suit _your_ PIC, as already tested to work.
#include <18F13K22.h>
#device ADC=10
#fuses INTRC_IO, PLLEN, NOXINST, NOMCLR, NOLVP, STVREN, PCLKEN, NOFCMEN
#fuses NOIESO, NOPUT, BORV22, NODEBUG, NOPROTECT, NOWDT, WDT512
#fuses HFOFST, NOCPD, NOCPB, NOWRTD, NOWRTC, NOWRTB
#USE DELAY(INTERNAL=32MHz)
#USE I2C(I2C1, MASTER, FAST=400000, FORCE_HW)
//display dimensions - the physical LCD
#define S_LCDWIDTH 128
#define S_LCDHEIGHT 64
#define TEXT_ONLY //If this is defined, gives a smaller text driver only
#define SSDADDR 0x78 //address for the chip - usually 0x7C or 0x78.
#include <string.h>
#include "ssd1306.h" //The OLED driver
void main(void)
{
int16 adcval; //variable to store the ADC reading
setup_adc_ports(sAN0 | VSS_VDD); //set this up for the pins
//and Vref you are going to use - demo on just AN0, and supply
setup_adc(ADC_CLOCK_DIV_64); //select according to data sheet
//for your clock rate/chip.
OLED_CLS();
size=LARGE;
while (TRUE)
{
//now the main code loop
delay_ms(500); //slow the loop to a sensible rate
adcval=read_adc(); //read the adc
//Now integer maths to give result in mV
adcval=(((int32)adcval*3300)+1650)/1024;
//This gives and int16 value of 0-3298 for 0 to 3.298v into the ADC
//assuming 3.3v supply
oled_gotoxy(0,0);
printf(OLED_putc("%5.3LWV ",adcval);
//display voltage on the LCD
}
}
|
This then displays the voltage as a nice x.xxxV on the LCD. |

It's actually possible to modify it with a little finangling.
Key is the definitions of the 'right hand' characters for the graph.
These are:
five clear bars, and the right bar on.
one bar at the left and one at the right.
two on the left and one on the right.
three on the left and one on the right.
four on the left and one on the right.
All on.
If you change the font definitions so these only use the left hand five pixels:
These are:
four clear bars, and the fifth bar on.
one bar at the left and the fifth on.
two on the left and the fifth on.
three on the left and the fifth on.
five on.
Then change the code to:
| Code: |
void OLED_textbar(unsigned int8 width)
{
//This draws a bar graph using text characters
int8 ctr;
unsigned int8 bar[9];
//This version is 0-100
//prints at current text location.
width/=2;
width+=1; //ensure >0
if (width>50)
width=51;
for (ctr=0;ctr<8;ctr++)
{
if (width>6)
{
bar[ctr]=134; //full bar
width-=6;
}
else
{
bar[ctr]=128+width; //partial bars
width=0;
}
}
//now handle the right hand end of the bar
bar[8]=135+width;
OLED_text(bar,9);
}
|
It should give a 0-100 bar. I'll leave you to do the font change needed (characters 135 and on). |

| Finally cracked the 0-100 textbar |
| Posted: Sun Jan 15, 2017 2:25 am |
|
|
I finally had some time over Xmas to finish my modification.
// modified to get 0-100
replace the last part of the font data with the following
| Code: |
0x82, 0x82, 0x82, 0x82,0xFE , 0x00, //final one closing shape 135
0xFE, 0x82, 0x82, 0x82, 0xFE, 0x00, //single left and right
0xFE, 0xFE, 0x82, 0x82, 0xFE, 0x00,
0xFE, 0xFE, 0xFE, 0x82, 0xFE, 0x00, //Now working in from the left
0xFE, 0xFE, 0xFE, 0x82, 0xFE, 0x00,
0xFE, 0xFE, 0xFE, 0xFE, 0xFE, 0x00 //final one closing shape 140 |
now to the function, it aint pretty, but it works.
| Code: |
void OLED_textbar_New(unsigned int8 width)
{
//This draws a bar graph using text characters
int8 ctr;
unsigned int8 bar[9];

Compiler: 5.026
Device: PIC24EP512GP806
Hi Ttelmah,
I'm using your code in text mode and it works and has worked for the last hour. But all of a sudden, it seems that 'something' is happening where, almost as if the display was separated in equal number of pixels per line and pixels per column for "large" fonts, what would be the very last column and last line are just random on and off garbled pixels all over the place without any specific pattern.
The last column of crap seems to be about 8-9 pixels wide and the last line of crap is about 4 pixels high.
Any idea what could cause this? It just happened all of a sudden. Even unplugging/replugging the entire unit, reprogramming the PIC, these lines keep appearing as garbage.
I will investigate more because there's no reason for that as it worked for the last hour and it just suddenly occurred but if you have an idea of what could cause this, let me know.
This is not an Adafruit display. I had this kicking around for like 3 years and I had ordered it from Hobby King. I never got to use it and paid like 2$ for it. It's just today I decided to have a try and *that* happened after working for a while.
Thanks!
Ben
[EDIT] The "problem" went away on its own. I had to shut off all my stuff because I was leaving and when I returned a few hours later, I turned it back on and this time the display was fine. So I'm wondering if somehow, the pixels stay charged for a while and a simple power reset doesn't work and the only way around this is to power-off the display for a prolonged period? Anyhow, it's weird.

If any user uses the sample code along with the sample main() code, just take note that in TTelmah's main example <mainssdtext.c>, he used <char text[9];> as a temporary text buffer.
Since the display handles at least 10 large characters wide per line with his driver, trying to print 10 characters caused half the line to be erased because it is trying to print a string longer than the buffer.
So change the '[9]' to '[11]' and that will get rid of that problem.
I'm pretty sure that it's not a bug on his behalf and more of an on-the-fly thing without really paying attention. In any case, I know I didn't pay attention to that detail and used his code as-is and I ran into the display problem. I thought it was in his driver code until I realized the problem was at the very begining and I should have paid a closer attention from the start.
Driver works well.

Not even that.
Remember the display can show 21 characters per line in the smallest font. I made the buffer large enough for the strings I was displaying. It is totally up to you how long you make your buffer....
As a further comment, I've just updated the actual routines to allow some further expansions. I've updated the 'master' routines above, and then posted some expansions below. |

Now adding some larger font abilities.
Requires the newer driver now at the top of the thread.
| Code: |
//Add this to the driver if you want to use larger fonts.
//Now handling for big font modes

Now the courier font is a complete 16*12 font from characters ' ' to '~'. This though uses over 2K of ROM!... Don't try to use on a small chip....
This is output using the new OLED_Btext routine (actually a #define), that accepts an alpha text string, and will accept LF, and terminate when it gets to the NULL ('\0') character.
Separately there is also a new 'NUM12' font. This draws just numbers (and decimal point and '/' ), making them as tall as possible in the larger font space. This uses 288 characters of ROM. There is a new optional #define 'BIG_PLUS'. If this is defined, this font gains six more characters (taking it up to 432 characters of ROM), and adding characters for the letter C, F, a copywrite symbol, degree symbol, and squared and cubed. These are not mapped into the normal character locations for these, so have to be used with explicit defines.
| Code: |
//same processor header
//display dimensions - the physical LCD
#define S_LCDWIDTH 128
#define S_LCDHEIGHT 64
//#define TEXT_ONLY //REM this out
//Size of graphics 'window' see the graphics section for explanation
#define WINDOW_WIDTH 64
#define WINDOW_HEIGHT 16 //sizes of the graphic window in pixels
//height must be a multiple of 8. //these must now be defined
#define SSDADDR 0x78 //address for the chip - usually 0x7C or 0x78.
#define BIG_PLUS
#include <string.h>
#include "ssd1306.h" //The OLED driver
#include <NUM12.h> //Load the large font for numeric and controls
void main()
{
int8 ctr;
char text[9]; //temporary text buffer
//Remember if you want to use this for longer text, you'll need to
//expand the buffer....
delay_ms(250); //OLED takes time to wake
//now try to initialise OLED
OLED_commands(init_sequence,sizeof(init_sequence)); //initialise the OLED
//First try some text
OLED_CLS(); //clear the physical screen
set=TRUE;
strcpy(text,"Hello");
size=NORMAL;
OLED_text(text,strlen(text)); //Standard font
delay_ms(1000);
sprintf(text,"123.4%c%c",DEGREE,LETTC); //number & symbols
OLED_CLS();
size=DOUBLE_HEIGHT;
OLED_Bnum(text); //Now display this big font doubled in height
while (TRUE)
;
}

If you load the courier font, you can instead use the 'OLED_Btext' function, and output the full normal character set, but at the cost of a lot of ROM. The smaller 'NUM12' font offers characters 16 pixels high, and in both case these can be doubled in height/width, to give 2 lines and just 5 characters across at the largest!...
Hopefully this has all posted correctly, and makes sense.

Hello everybody
A very big thank you for this brilliant code to drive a SSD1306 driver with a small RAM space. it's work perfect! i like the printf (OLED_putc) function! easy to use.
Tested on a PIC18F46K80 with 32MHz and 64MHz internal oscillator, Slow and fast I2C Hardware mode (Fast=80000 (80000 because there is a capricious PCF8574 I/O extender on the bus and fast speed "Fast=400000" without the I/O extender
1/
Now, I'm searching to display a simple logo at startup of my application with this code in "TEXT_ONLY" mode
but I don't know how to send a complete array of 1024 byte to the display
before to used the code of Ttelmah, I used first the code from SuperFranz (Thank you very much SuperFranz) and i was able to display a logo. (......const INT LOGOS [1024] ={ array of 1024 bytes....the picture}; )
Is there anyone on this forum who could open my eyes on how to do this job?
2/
Because, my application is powered with a battery, i try to obtain the minimum power consumption with this SS1306 Oiled display but it seems (i measured) that the power consumption of the display with all oled dot OFF is 1.6mA! it's too much!
Is there is a SLEEP command to send to the display?
I read on the web that there is a DISPLAY_ON/OFF (sleep!!!) command, a brightness Command....and a CHARGE Pump Command (internal switching regulator.......i suppose that it take some mA!)
To sleep the module, could it be with
| Code: |
ROM BYTE SLEEP_sequence[] =S_SETCONTRAST,
0x00,
S_DISPLAYOFF,
S_CHARGEPUMP,
0x10; // Charge pump OFF
ROM BYTE WAKEUP_sequence[] =S_CHARGEPUMP,
INT_VCC; // Charge pump ON (0x14)
S_DISPLAYON,
S_SETCONTRAST,
0xCF; // 0x00 to 0xFF
//OLED Display Sleep
OLED_commands(SLEEP_sequence, sizeof(SLEEP_sequence)); // SLEEP MODE
//OLED Display Wakeup
OLED_commands(WAKEUP_sequence, sizeof(WAKEUP_sequence)); // Wakeup sequence
|
I cannot try because I'm not close to my wish board for a moment! ;-(
Do you have any experiences with that?
Wish you a great day to all.
Mani

Hello Again,
I just try this:
| Code: |
ROM BYTE SLEEP_sequence[] =S_SETCONTRAST,
0x00,
S_DISPLAYOFF;
ROM BYTE WAKEUP_sequence[] =
S_DISPLAYON,
S_SETCONTRAST,
0xCF; // 0x00 to 0xFF
//OLED Display Sleep
OLED_commands(SLEEP_sequence, sizeof(SLEEP_sequence)); // SLEEP MODE
//OLED Display Wakeup
OLED_commands(WAKEUP_sequence, sizeof(WAKEUP_sequence)); // Wakeup sequence
|
It works perfectly!!!
Before 1.6mA
Now with DISPLAYOFF command : 0.00645mA! (6.45µA)
I put definitely to the trash my old LCD Display 8x2.
I'm happy! 
Best regard
Manu

I do a large logo on one of my units.
I just have it declared in ROM as:
| Code: |
ROM BYTE const Plogo[] =
{
//With 512 bytes of data here.
};
//Then send it with:
//Move a line from the ROM array into RAM
void get_line(ROM BYTE *array, BYTE * target)
{
int16 ctr;
for (ctr=0;ctr<64;ctr++)
*(target++) = array[ctr*8];
}
void draw_logo(void)
{
BYTE line[64];
signed int16 y;
//routine to write the logo
//Logo is in a 512 byte array, designed to occupy the second half of the screen
//each row on the screen is every eighth byte along the array
set=TRUE;
size=NORMAL;
OLED_cls();
for (y=7;y>=0;y--)
{
OLED_address(62,7-y); //position the display
get_line(&logo[y],line); //64 bytes
OLED_data(line,64);
}
|
The key is the use of OLED_address then OLED_data to send a line of data.
It's a decision you would have to make as to whether you should write a version accepting constant data or (as I do), just buffer the lines.
This occupies the right hand half of the screen.
Have fun. |
