how to print long long (double) or int32?
| Code: | int32 test = 16777215
printf("%Lu", test); |
resoult is 65535.
how to print value larger than 65535?

What compiler version do you have?.
%Lu should print this fine, provided the value genuinely is an int32.
Some of the very early V4 compilers had problems with int32 (about 4.119
I think). |

I've just built a test with 5.101, and a PIC18F2420.
Merrily works:
| Code: |
#include <18F2420.h>
#device ADC=10
#FUSES NOWDT
#use delay(crystal=20000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,errors)
void main()
{
int32 test = 16777215;
setup_adc_ports(NO_ANALOGS, VSS_VDD);
printf("%Lu", test);
while(TRUE)
{
delay_cycles(1);
}
}
|
Outputs to the terminal : 16777215
This on a basic MicroChip prototype board (20MHz crystal). |
