candleLight_gsusb

This is a firmware for stm32f0-based USB-CAN adapters, notably:

• candleLight: https://github.com/HubertD/candleLight
• cantact: http://linklayer.github.io/cantact/
• canable (cantact clone): http://canable.io/
• USB2CAN: https://github.com/roboterclubaachen/usb2can

It implements the interface of the mainline linux gs_usb kernel module and works out-of-the-box with linux distros packaging this module, e.g. Ubuntu.

Be aware that there is a bug in the gs_usb module in linux<4.5 that can crash the kernel on device removal.

Here is a fixed version that should also work for older kernels: https://github.com/HubertD/socketcan_gs_usb

The Firmware also implements WCID USB descriptors and thus can be used on recent Windows versions without installing a driver.

To Flash a Canable board on Linux

1. Install dfu-util sudo apt install dfu-util
2. Press the boot button on the Canable board while plugging in the micro usb
3. Release the boot button
4. Navigate to the bin directory of this repo
5. Run sudo dfu-util -d 0483:df11 -c 1 -i 0 -a 0 -s 0x08000000 -D gsusb_canable.bin

To compile firmware for a Canable board on Linux

Requirements: arm-none-eabi-gcc - sudo apt-get install gcc-arm-none-eabi

1. Navigate to the root directory of this repository
2. Run make BOARD=canable
3. This will generate multiple bin files. The file needed for the canable device is gsusb_canable.bin shown above
