Nhiều RS232 trên một PIC

[cskiller]

Trong CCS C dùng nhiều software RS232

#use rs232(FORCE_SW, baud=9600, xmit=PIN_D0,rcv=PIN_D1, STREAM=ID1)
#use rs232(FORCE_SW, baud=9600, xmit=PIN_D2,rcv=PIN_D3, STREAM=ID2)
#use rs232(FORCE_SW, baud=9600, xmit=PIN_D4,rcv=PIN_D5, STREAM=ID3)
#use rs232(FORCE_SW, baud=9600, xmit=PIN_D6,rcv=PIN_D7, STREAM=ID4)
...
putc("C",ID1);
...
puts("Put data to software RS232 stream id 1",ID1);
...
getc(ID1); //Get data from software RS232 stream id 1
...
gets(buff,ID1); //Get data from software RS232 stream id 1
...
fprintf(ID1,"String formated to software RS232 stream id 1");
