A driver for the Silicon Labs CP2130 USB->SPI bridge IC, exposing an embedded-hal compatible interface as well as a command line utility for interacting with (and testing interaction with) CP2130 devices.
WIP. Basic functionality working, PRs for extended features (non-volatile programming, alternate pin modes, etc.) are absolutely welcome.
You can install the utility with cargo install driver-cp2130 or grab a pre-compiled release from here
You may wish to copy 40-cp2130.rules to /etc/udev/rules.d to allow all users with plugdev permissions to interact with the CP2130 device.
