conflict between int_rda and spi, how to stop int_rda?

[Petar]

Hello,

I've to control the interrupt "int_rda". How can I stop the INT and than start again?

// code example
#include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOBROWNOUT,NOPUT
#device ADC=10
#device *=16
#device ICD=TRUE
#use delay(clock=20000000)
// #use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7, parity=N,bits=8,stream=, DISABLE_INTS)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7, parity=N,bits=8,stream=)

...

INTREG_RS232 = 0; // #bit INTFLAG_RS232 = 0xf9e.5
// The INT stops correct

Write_Block_512(max_mmc_count); // SPI routine

INTREG_RS232 = 1;
// !!! The INT doesen't work again ????


Has anybody an idea, how the INT can be reactivated??

Thanks a lot!!

Regards
Petar

I suspect you are getting an overrun error in the hardware USART.

To fix this problem add the errors directive to the end of the statement:
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)


Also, two other things:

1. You don't need #device *=16 with the 18-series PICs.
It's only needed with the 16-series PICS (16F877, etc.)

2. You very likely need to add NOLVP to the end of your #fuses
statement.

This is what I do...

To stop:
bit_clear(RCSTA, 7) //Serial port disabled

To re-start;
bit_set(RCSTA, 7); // Serial port enabled
bit_clear(RCSTA, 4); // By clearing CREN you clear overrun error
// on OERR
bit_set(RCSTA, 4); // Enables mode again

Cheers
