I'm not sure if this would work but does anyone know what board the usb dongle for the logitech ps3 controller uses i tried looking around and have got nothing except it works on the computer as a USB HID so would i neeed to use amtel and try to load different firmware if possible and would it be fixable if screwed up?
don't waste your time, buy a compatible board or a TI-84. I went with TI-84 off ebay for $38 bux free shipping. I have bought 1 for myself & 4 others for friends from the this seller, shipping is a bit slow but worth the wait.
a logitec dongle is only going to be an rf device paired with a usb port, which is nothing to do with being programable for other uses. you need something which has a brain, not just a simple function.
