LIBUSBSIO Library

Mission

The aim of this project is to deliver a dynamic library which enables USB-HID communication between PC Host and a target MCU over SPI, I2C or GPIO using a USB-connected bridge device. Two types of bridge devices are currently supported: LPCLink2 and MCULink. The library is supported on Windows/Linux/MacOS platforms.

The project uses the HID_API open source library code and partially also its new libusb/hidapi version to access the USB HID interface on all supported OS platforms.
