Can't get LCD to work with 16F88

[Bruce]

You're very welcome. Glad I could help.

< can't find anything on DECx except for in the reserved word list

DEC isn't a PBP command. It's what's referred to as a "data modifier", and you'll see it in the manual under the LCDOUT, SERIN2, etc, commands.

If you're using the TXLC/RXLC modules, just remember to hold the transmitter data input at logic 0 during idle periods.

These modules are CPCA (carrier present, carrier absent), and super easy to use.

You're simply turning the transmitter carrier ON with logic 1, and turning it OFF with logic 0. Think of the logic on the transmitter data input as an ON/OFF switch.

The receiver just reflects the same logic states on its data output. TX input = 1, carrier = ON, RX output = 1. TX input = 0, carrier = OFF, RX output = 0. Doesn't get much easier.

Very stable receiver output, and incredibly simple to use.

Enjoy...;o]
