Thank you!

It worked. No MAX232, so I needed that INVERT.

Thanks again,

Hi,

I am trying to connect PIC using RS232 to a PC (using HyperTerminal to read from the PIC (18F452)).

The problem is that no matter how I set the parity and data bits with #use RS232 and no ...

Same problem with Timer0.

#include <16F877A.h>
#device ICD=TRUE
#device adc=8
#use delay(clock=4000000)
#include "math.h"
#fuses NOWDT,NOPROTECT,NOLVP
#use delay ...

Put the 4MHz crystal in, but still no change with different overflows... I am going to try timer0, just in case.

I just looked at the crystal, and its clearly 40MHz. I got this board from a friend who was using it for PIC18 chips, so it might as well be too fast for my PIC16. I guess I will see if he has slower ...

Thanks guys. That must be it... From what I recall on one of the boards from Microchip, you can select between the internal and external clock (crystal). Is that correct ?

Anyway, I am curious why ...

1. PIC16F877A
2. I did not specify any fuses
3. #use delay(clock=40000000)

I am pretty sure it is 40Mhz because that is what it says on the crystal oscillator.

Here I am trying to finish the timing equipment for a local car club by friday, and my timer is acting up. I know it is some silly thing, but I cannot see what I am doing wrong.

All I am trying to ...
