I am very new to electronic projects but I am building a button box from a tutorial on YouTube. It is a 32-function button box for American Truck Simulator's PC game. I will provide pictures of the button layout, the wiring diagram, and the code I used. The problem is I used a different button layout than the tutorial one and therefore had to change the code to accommodate my button layout. All buttons work but when I press the 5 buttons that correspond to the rows they all press the same button. For example, the 5 buttons on row A1 are all pressing button 1 and so on for the rest of the rows but I need them to use all 25 buttons. Also, the buttons in row 16 don't work at all. There is a rotary encoder in with the buttons and surprisingly the turn function works but the button presses the same as the others in the row. If someone can help point me in the right direction that would be fantastic and thanks in advance. If I haven't put the right information please let me know what else is needed.
