I am a beginner to PIC programming and I am using PIC 18F6722 to drive NKK Smartswitch LCD.

// As defined in the following structure the pin connection of Port F is as
// follows:
// F0 rs
// F1 rw
// F2 enable
// F3 LCD_LP
// F4 LCD_DOUT
// F5 LCD_BL
// Pins F6 and F7 are not connected

How can I modify flex_lcd.c to drive 36 X 24 pixel NKK Smartswitch LCD

The flex_lcd driver won't work with the NKK SmartSwitch. It's a
completely different type of display. They have a sample driver
here, written in Microchip ASM source code:

Click the Download button to get it.

You'll have to convert it from ASM to C code. Please don't ask me
to do this for you.

Here are other resources:

Please do not ask me to translate the C code to CCS for you.
This is your project. You must do it.
