Here is a quick System Over View as a start point.
The first project I am working on is a USB-to-SPI Bridge, UTSB. This bridge will manage or connect a system on the USB bus to systems on the SPI bus.
MCU Chosen for this system: PIC24HJ256GP610A
Used Microchip USB Stack and SPI Hardware interface
Started with the CDC Emulator Project provided from Microchip examples for the PICDEM FS USB.

- example code for the System
- Protocol used to control the UTSB
