Soft RS232

Posted: Sat Apr 01, 2006 6:42 am

Hi,
Just a note on how I resolved Software RS232, Sending Garbage Characters. I could get the RS232 to work on the built in UART, however when program for software UART, I was receiving Garbage Characters. Confused

Code:

#use rs232(Stream=Wview,baud=9600,xmit=PIN_B7,rcv=PIN_B6,bits=8)

After reprogramming my code under RTOS, I found the RS232 working as expected. I the reprogram back and found that the interrupt had cause this problem. After disabling the interrupt All works Well Rolling Eyes

Code:

#use rs232(Stream=Wview,baud=9600,xmit=PIN_B7,rcv=PIN_B6,bits=8,DISABLE_INTS)

You probly need to add E: in your RS232 The PIC® is Sending Garbage Characters. (To add DISABLE_INTS in your #use rs232 if you are using interrupts) Wink
