i forgot the while(1) at the end so it wouldn't sleep

hi i setup my pwm as such

EDIT: reposted code

#include <18F2680.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7 ...

ya .. humberto i took the statements out .. yes my reasoning was flawed

anyhow .. another question

currently I use pins b0 and b1 for RX TX .. is it possible to us b2 as say another RX pin sin ...

ya .. i edited it bc the pull down did not work .. and rather what i put above did Smile

I added output_low(pin_B0) and output_low(pin_B1) to both RX and TX chips and that seems to solve the issue .. pin B0 went high on the RX chip at turn on and caused the int on the TX

2) ya .. my question is why did the interrupt trigger in the transmitting pic when it is the only one sending characters

Does the receiver is echoing something while receiving ?

What is the #USE_RS232 defintion for the getc?...

Best Wishes

From the ex_crc.c example in the example folder the #use rs232 line for pic to pic comm is

#use rs232(baud=9600, xmit=PIN_B ...

my TX PIC will hang at the interrupt at the getc()

1) How did you determine that the program hang in getc ?

2) To stay in getc implies that the interrupt was triggered by a falling signal b ...

Hi,

I am implementing this example verbatim. I am using a 18F2680 but pin assignments are the same for this example.

In main .. interrupts are enabled :

ext_int_edge(H_TO_L); ...
