The existing LCD.c driver can handle PORTD or PORTB and only 4 DATA ports.

How do I change the standard LCD.c code to accept 8PIN data rather than 4PIN data for LCD connections? (either PORTD or PO ...

thank you for your detailed explanation.

you are a great resource in this community.

Thank you for your reply. It does confirm my original thoughts that having a larger buffer helps with ASYNC data transfer.

The reason I asked the question is because, each time I "enable_inte ...

Thanks

It is working great!.
Thankx

thankx for the help. I'll try it today.
