MCP41XXX SPI Write

[Darrel Taylor]

Do you have a pull-up resistor on PORTA.4?

It has an "Open collector" output, and can't go HIGH by itself.

Garsh, I think that's it. I knew there was something about one of the pins I was forgetting. I'll try that tonight and see what happens.

So long as I use the CMCON=7 command, is porta.4 the only tricky pin I need to worry about? I also set the configuration byte to disable everything.

Thanks!
