18f4550 portc.4 and portc.5 problem

[Darrel Taylor]

Hmmm, perhaps I need to spend some more time in the USB section.

I thought setting UCFG.3 to "External transceiver" would wipe out ...

RB2 - RB2/AN8/INT2/VMO
RB3 - RB3/AN9/CCP2(1)/VPO
RC1 - RC1/T1OSI/CCP2(1)/UOE

In my project all the pins VMO / VPO / UOE are used as digital outputs.
I test them...and with UTRDIS = 1 (UCFG.3 = 1) I can use in TTL input RC4 and RC5 and in the same time I can use RB2 RB3 and RC1 as output...(RC1 transmit serial data at 38400Bps, RB2 AND RB3 send command to activate/deactivate rele').
If you think may be interesting to test other possibilities...tell me something about. I will do it!

Nope, that's Great information!

I'll see if I can find a few extra brain cells to store it in.

I'll put a mark on the chalkboard for skimask too.
