LCD Unable to display with SK40C
Posted: Fri Jan 12, 2018 3:45 pm
I can get the LCD display working properly when connecting LCD externally instead of using the port provided in SK40C.
Used PORTD for DATA and PORTA for LCD control. No issues.
When I connected the LCD to the LCD port provided in SK40C, it is unable to work. LCD powering and contrast adjust ok.
I changed the control port setting to PORTB.
I also made the changes to the XCLD.h library to reflect the correct port pins.
It is just a simple program showing "Hello World".
Using 18F4550 device.
Need help.
