| 2 rs232 on PIC |

How can I use two rs232 channels in one program?
And how to say printf() function to use one or the other rs232?
Thanks for examples. |

Search the help file and readme.txt file for "streams". Also you can search the forum for "streams".

If you have a really old version of the compiler that does not support streams then multiple serial ports is still possible but complicated. Let us know if you are in this situation.

| Code: |
#USE RS232(BAUD=9600, XMIT=PIN_B0, RCV=PIN_B1, STREAM=COM_A)
#USE RS232(BAUD=9600, XMIT=PIN_B2, RCV=PIN_B3, STREAM=COM_B)
main() {
char c;
fprintf(COM_A,"Porta A\n\r");
fprintf(COM_B,"Imprime em B\n\r");
while(TRUE) {
c = fgetc(COM_A);
