| My #int_RDA can't work on PIC24F256GB106 |
 Posted: Thu Feb 11, 2010 11:59 pm |

My CCS Verison is 4.104 for "PCDIDE Compiler".
I'm use "PIC24F256GB106" for RS232.
If I no use "#int_RDA" that PIC will be normal work.
But when I use "#int_RDA" function that PIC will unceasing redundant reset.
It will not do main function !
Where is bug at my code ?
These is normal work code.
| Code: |
#include <stdio.h>
#include <string.h>
//********************************************************************
#pin_select U1TX=PIN_G6
#pin_select U1RX=PIN_G7
#pin_select U2TX=PIN_D8
#pin_select U2RX=PIN_D9

#use rs232(UART2,baud=115200,parity=N,bits=8,stream=comb)
//********************************************************************
void main()
{
//setup_spi(SPI_MASTER | SPI_MODE_3 |SPI_CLK_DIV_1);
//setup_spi2(SPI_SS_DISABLED);
setup_wdt(WDT_OFF);
setup_timer1(TMR_DISABLED|TMR_DIV_BY_1);
enable_interrupts(INT_RDA);
enable_interrupts(INT_RDA2);
enable_interrupts(INTR_GLOBAL);
//****************************************************************
for(;;)
{
fprintf(coma,"comb test a ... \r\n");
fprintf(comb,"comb test b ... \r\n");
delay_ms(2000);
}
}

If I add #INT_RDA function that PIC will reset again and again
There is bug code.

- Interrupt nesting is disabled by default, you don't need to disable or enable any interrupts in the interrupt function.
- You're writing one byte out of bounds of your rx buffers (rs_buffb[512]).
Apart from these points, I don't see problems with your code. RS232 interrupts are generally working with PIC24 chips and recent PCD versions. |

Has the problem with the UART numbers being reversed, been fixed?.
If not, then the code would hang.
I really would suggest, getting just _one_ UART working first.

Yes, if I remember right. But it's a good idea to check correct SFR usage and PIN_SELECT coding anyway. It has
been partially wrong with PIC24FJxxGB1xx in previous compiler versions and is still wrong for some more exotic
PIC24 types. |

I will continue try. This week is chinese new year , I have seven day's holiday.
Next week I will try again ~ |
