Does anybody have an idea why the interrupts doesn't work ?
I have the same issue with the PIC16F690.
In the following code, the Touch Sense works perfectly.
Note, i am using the CCS 5.080
Thanks
| Code: |
#include <16LF727.h>
#device ICD=TRUE
#FUSES NOPUT //No Power Up Timer
#FUSES MCLR //Master Clear pin enabled
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOBROWNOUT //No brownout reset
#FUSES BORV19 //Brownout reset at 1.9V
#use delay(internal=8000000)
#use rs232(baud=9600,parity=N,xmit=PIN_E1,rcv=PIN_E0,bits=8,stream=PORT1)
#use i2c(Master,Slow,sda=PIN_C4,scl=PIN_C3)
#use touchpad(pin_b1='0', pin_d0='3', pin_d1='6')
char car;
#INT_RDA
void RDA_isr(void)
{
car=getc();
putc(car);
}
void main()
{
enable_interrupts(INT_RDA);
enable_interrupts(GLOBAL);
while(TRUE)
{
;

This is the main problem:
If you want to use the interrupt then you must use the hardware UART that's on pins C6 and C7. So instead of xmit and rcv, replace that with UART1.
| Code: | | #use rs232(baud=9600,parity=N,UART1,bits=8,stream=PORT1,errors) |
Some other comments:
You also need to use the ERRORS option in the rs232 setup or else your uart will lock up when there's an error. ERRORS will automatically clear errors. I also highly suggest using the RECEIVE_BUFFER option instead of making your own INT_RDA. That will make the compiler automatically generate an ISR that puts received characters into a circular buffer that you can access from your main loop.

| Same thing with the 16F690. The hardware UART is on pins B7 and B5. |
