UART on PIC16F688

[guest]

I have found the same problem with the 16F688, I was able to transmit data using TXREG but not the standard putc() CCS includes by using #use rs232. why is that? do you know?

You will also need to create your own putc() and getc() functions.
I will show you how to make the putc() function:

#byte PIR1 = 0x0c
#bit TXIF = PIR1.1

#byte TXREG = 0x15

void my_putc(char c)
{
while(~TXIF);

TXREG = c;
