Hi guys.
I have problem with my project. I used Nintendo touch panel for my project. I already succeed display the coordinate x and y. The problem now is I want to combine nintendo touch panel with other circuit. My friend said I need to put same ground for nintendo touch panel with other circuit if I want it synchronize control by arduino. I tried to put ground on nintendo touch panel. But the value become zero. So my question is do I need to put same ground nintendo touch panel circuit with other circuit. Or I just connect analog input arduino to my nintendo touch panel circuit?
