looking at your schematic..how are you using the uart for the lcd ? your loading 4bits at a time...
if this is not pcb, i really think the easiest way is to use the uart. You would only to switch one pin around.
Back to your question, i'd probably say the second is easiest if you have the components available. Otherwise, ra2 as a serial out. which is a bit more work then.....using....the...hardware....u....a..r..t....
OK, as some pins from 16F88 is actually reserved for UART, right? But I juz found out that as long as there is an IO pin, i can use it as serial output. correct me if i am wrong.
It is not a PCB. but it can used both to display at LCD and serial out to module?
So using shift register is hardware UART?
