Hi I have uploaded your code, everything works except the characters are all in the wrong place i.e. if I press the '7' I get the '/' instead. I am using an Eelegoo 2.4" display so I imagine that I need to change some of the code. Any help would be gratefully received as I am quite new to this. Rich

You can change the characters in the code. But the code has no errors. char button[4][4] = { { '7', '8', '9', '/' }, { '4', '5', '6', '*' }, { '1', '2', '3', '-' }, { 'C', '0', '=', '+' } };
