Hi, I have tried to build two boards. unfortunately it doesn't work as it should... the display in the software flashes back and forth... some buttons work... but as soon as i connect it to windows as HID it doesn't really work anymore... the board with the arduino on it doesn't work at all. I don't know if I've built something wrong... maybe someone can tell me where the error lies... i also use 10k resistors... is that the reason for the blinking ? hope someone can help me... because i'm slowly going crazy .thanks
