Weird problem for working on 2 UARTs |

Hey guys,
I'm using PCWHD v4.114 for programming dsPIC30F6014A. Below is my coding:
Dual UART initialization
Code: | #use rs232(UART1,baud=9600,parity=N,bits=8,xmit=PIN_F3,rcv=PIN_F2,ERRORS,stream=MCC)
#use rs232(UART2,baud=9600,parity=N,bits=8,xmit=PIN_F5,rcv=PIN_F4,ERRORS,stream=GSM)
|
Code: | fprintf(MCC,"test dual RS232, this is UART1\n\r");
fprintf(GSM,"test dual RS232, this is UART2\n\r"); |
- this froze the mC, nothing comes out of UART.
Code: | fputc(0x41,MCC); //A in Hex
fputc(0x54,GSM); //T in Hex |
- works, no problem.
Code: | puts("UART1", MCC);
puts("UART2", GSM); |
- works, no problem.
Code: | fprintf(MCC,"test dual UART\n\r");
fprintf(GSM,"test dual UART\n\r"); |
- works, no problem.
So, it seems like if string is similar for both UARTs, fprintf can work... if not, nothing comes out.
Code: | fprintf(MCC,"test dual RS232\n\r");
fprintf(GSM,"test dual RS232\n\r");
delay_ms(100);
fprintf(MCC,"test dual UART\n\r");
fprintf(GSM,"test dual UART\n\r"); |
- this froze the mC, nothing comes out of UART.
Even so, if needed to change the string, still cannot work.
Please help, thank you. |

Most people don't have the PCD compiler. I don't have it. That's why
I didn't respond. This type of problem is "right up my alley", but I can't
help you. |

Well , I've got the compiler, but don't have any dsPICs ! So I can't help either as I only test with real chips. |
