Hi there,
I used XLCD library in my C code, to display a message on LCD Display (2x16, with HD44780 LCD controller) using the PIC18F4525, I compilled the programm successfully, and made a schematic on ISIS in order to simulte it but, I failed to get anything to display !!!
besides the PORTA0 which is configurated as DATA PORT remaind in low level during simulation, on the other hand PORTB (which is not used in my application) had varied level in its outputs (see joined picture).
what is the resaon of this abnormality ?
I have another question, does the ISIS LCD display include the HD44780 LCD controller , or should I add it from the libray the scheme?, if it's the cas how will I display ??
I joined my project compiled+ISIS simulation file+ a prints screen of ISIS schematic.
thanks in advance.
