Hello all,
I'm new to this forum, but just wondering if I could pick your assorted brains on a PIC related issue (no pun intended, honest).
I'm building PWM LED multiplex driver using a PIC 16F627A; thanks to other posts on this forum I've got my driver transistors working correctly for rows and columns, and my software PWM code is working nicely. However, I am unable to get the column attached to pin RB2/TX/CK to function; I suspect that this is because I am using the PIC's UART to talk to a host computer over RS232. Although the port is set as an output in the TRISB register, I have a nagging feeling that enabling the UART forces this to be the serial transmit pin. Is this the case?
Thanks,
Gavin
