DO NOT change the power supply to your ARM board ! You will destroy the board and the processor.

Best to use 3.3V-5V voltage translator board, 3.3V to 5V boost converter and jumper leads.

I made my COG work without level translators, but this may be operating outside of specification and/or may not work for you. You run a high risk of destroying your board and processor if you try it, as you need to break the VCC line to the COG and provide split supplies. I TAKE NO RESPONSIBILITY IF YOU TRY !

Messing with 5 Volts anywhere near a board designed for 3.3V could end in disaster.

I'll have to buy an additional card or just change the power supply board EasyMxPro V7?

Run up your compiler

Open the 'library manager' tab

Expand the 'Lcd' library option

Double-click on 'Lcd_Init' to get help on the function

Scroll down until you find the 'Library Example' Heading

Select the tab for your processor

Copy and paste the sample code into your editor, then compile and program

COG board requires 5 Volt supply, so you will need a 3.3V to 5V translator board and a source of +5V
