Hi,
I want to connect my LCD to PORT A of my pic16f84 mc but i think the connection is only possible through port B...But my port B is reserved for interrupts..
 

There is no restriction in connecting any port to LCD. You can use PORT A to connect LCD

but please post the program in ccs....i now to do this with mikroC but i don't know how with ccs
 

Hi! no problem u can use PORTA for your LCD but keep this in mind that Pin RA4 is multiplexed with the Timer0 module clock input to become the RA4/T0CKI pin. did u consider this? if this help tell me.
 

a 44780 compatible lcd need 6 I/O lines for comunication (D4,D5,D6,D7,E,RS). PortA of 16F84 have only five.
 

I know friends and i also did it mith mikroC but i need the code in CCS and i don't know whether CCS lcd.c driver support other port or not please post code if you know...



Thanks.
