Using a PIC with USB, accelerometer, and gyro for tilt-based gaming

For the hardware I used the Acc_Gyro sensor and a thumb-size PIC platform UsbThumb built around the inexpensive PIC18F14K50 chip that provides all the necessary USB connectivity and ADC inputs.

This setup is actually hardware compatible with my original Motion Gamepad design so all the software utilities and firmware will work on the Acc_Gyro + UsbThumb combination that is available as a kit under the name of UsbThumbImu. The Acc_Gyro fits on top of UsbThumb and this is not a coincidence since UsbThumb was designed as microcontroller helper for the Acc_Gyro with the idea of being able to provide the USB/Serial/SPI/I2C interface, as well as making use of the built-in 10bit ADC module of the PIC18F14K50.
