1. Post a very short test program that shows the problem.
2. Post your compiler version.
3. Are you testing this with hardware or a simulator ?
4. If hardware, describe the display device (Hyperterm, LCD, etc.).
This is an example of a test program:
Code: |
#include <18F2525.h>
#fuses XT,NOWDT,NOPROTECT,BROWNOUT,PUT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
//====================================
void main()
{
int8 x = 50;
printf("x = %d\n\r", x);
while(1);
} |

Here is the program I was using for test. I am using a 20MHz oscillator, and reading the input on hyperterm. I tried several different baud rates, but all had the same results. I also experimented using different length integers. As I said before, I'm not 100% sure on the compiler version, but I'll be able to post it tomorrow.
#include <18F2525.h>
#device adc=8
#fuses NOWDT,WDT128,HS, NOPROTECT, IESO, BROWNOUT, BORV20, NOPUT, NOCPD, STVREN, NODEBUG, NOLVP, NOWRT, NOWRTD, NOEBTR, NOCPB, NOEBTRB, NOWRTC, NOWRTB, FCMEN, XINST, NOPBADEN, LPT1OSC, MCLR
#use delay(clock=20000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8)
#use i2c(Master,Fast,sda=PIN_C4,scl=PIN_C3)
void main() {
int16 kp=50;
printf("TEST\n\rI initialized kp to 50\n\r");
printf("kp = %ld\n\rEND TEST\n\r\n\r", kp);
while(1);

The XINST fuse will enable the Extended Instruction Set. CCS doesn't
support this. The 18F2525 data sheet says this, in section 24.2.3:

Enabling the PIC18 instruction set
extension may cause legacy applications
to behave erratically or fail entirely.
|
Change it to NOXINST. |

I'll give that a try. Thanks for your help. |

That solved my problem, thank you. Does CCS version 4 support the extended instruction set? I realized that we are using 3.224 here. |
