Defining different Ports for LCD
PostPosted: Sun Mar 30, 2008 1:19 pm     Reply with quote
Hello,

I have a question about connecting an LCD. The LCD is connected to a PIC16F873A. DB0..DB5 are connected to Port_A 0..5. DB6..DB7 is connected to Port_C 0..1. How do I define these Ports to write to the LCD with only one 8Bit-value?

Can I use the lcd.c file in my hardware setup? I tried to add it in my project file, but if I build the project, I get the errormessage "Invalid Option: +EXPORT". But this option is not set in the build options. What could be the problem?

Best regards

Olaf

Use this LCD driver. It's a lot easier to use:

See the answers in this thread. They explain how to use multiple source
files with CCS in MPLAB.
