I'm seeing an error with printf using signed int16. I'm always getting the last number to be returned as binary.
Example
(led_putch is an LED output routine)
signed int16 temp;
temp = 215;
printf(ledputch, "\n%ld", temp);
What I get passed to led_putch is '\n', '0x32', '0x31', '0x05'
If I change the format to "\n%lu" everything returns as ascii.
Anyone else seeing this? |

You didn't give your compiler version, which can make all
the difference in the world.
The following test program works OK with PCM vs. 3.190.
It produces this output on the terminal window:
| Code: | #include <16F877.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
void ledputch(char c)
{
putc(c);
}
//=====================
main()
{
signed int16 temp;
temp = 215;
printf(ledputch, "\n%ld", temp);
while(1);
