USB HID Data Gateway

At the moment, this project is a simple USB stack implementation for Atmel SAM D21 (D11).

Demo application is a very simple and inefficient USB HID to I2C, SPI, GPIO, ADC, DAC and PWM adapter.

Demo CLI application uses I/O1 Xplained Pro board to:

• Read/write EEPROM and read temperature from the AT30TSE785
• Test if GPIO1 and GPIO2 pins are shorted to demo GPIO capabilities
• Test SD Card interface (SPI mode)
• Test ADC (PA03) and DAC (PA02).
• Test PWM (PA10 and PA11)

I/O1 Xplained Pro has to be attached to EXT1 connector of the SAM D21 Xplained Pro board.

Future versions will improve on this and implement other interfaces.
