I want to receive data from my pc to the PIC. I have configured everything (not sure if it is correct) but there is no interrupt generated.
#pragma DATA 0x2007,0x3D0A 'HS OSC #pragma CLOCK_FREQ 16000000 sub interrupt () dim Data as byte porta.3 = !porta.3 'to test if interrupt gen. but doesn't do anything if pir1.5 = 1 then Data = rcreg 'process Data ... pir1.5 = 0 end if end sub sub main() trisa.1 = 0 trisa.2 = 0 trisa.0 = 0 intcon = intcon | (1 << PEIE) 'enable peh. interrupts intcon = intcon | (1 << GIE) 'enable global interrupt pie1 = pie1 | ( 1 << RCIE) trisb.1 = 1 'enable for input trisb.2 = 1 ' " " " spbrg = 207 '@ 16Mhz: 1200 baud txsta = txsta & ~ (1 << BRGH) txsta = txsta & ~ (1 << SYNC) rcsta = rcsta | ( 1 << RX9) rcsta = rcsta & ~ (1 << ADEN) txsta = txsta | (1 << CREN) rcsta = rcsta | ( 1 << SPEN) cmcon = 7 'program starts here.... end sub
Anyone knows if this code is correct? Also the signal at RX pin is this inverted from the PC signal or is it the same?
Configuration at pc: 1200 baud, no parity, 8 bits, 1 stop bit
