Hi Steve,

Thanks for the suggestions.
Yes, the rest of the LCD wiring are “as usual”.

However when I try to set the config fuses I get an error in MCS+ “Argument out of range (not a valid config register address)”

Even with only “@ __config _INTRC_IO” I get the same error. I am new to the 16F88, previously I have used only the 16F628A and no such errors occurred.

Thanks.
