Generic USB interface device for driver development and hardware testing

Very early alpha. Firmware working, library has restricted functionality.

• Generic device to allow control and interaction with embedded hardware allowing native driver development and hardware unit testing
• LibUSB based support for I2C, SPI, GPIO (with interrupts), ADC and PWM

• arm-none-eabi-gcc (from launchpad or use source armenv.sh for a local instance)
• cmake
• make
• clang (or gcc)

First, initialize the project with the following:

1. Checkout this repository
2. Initialize submodules with git submodule update --init --recursive
3. Build all components with make all

1. Switch to the firmware/library directory
2. Install with make install

1. Switch to the firmware/build directory
2. Build the firmware with make
3. Flash the firmware to the device with make flash

1. Switch to the software/build directory
2. Build the software with make
3. Run with ./usb-thing

• firmware - device firmware sources and build tools
• library - usbthing shared library, this includes all libusb calls
• common - common protocol definitions shared between the firmware and library modules
