I'm considering taking on a small project to develop a free
USB CAN adapter. I am wondering if anyone would have any
interest in this.
My current thoughts are to use an STM32F105 as this has USB OTG
(I would only use the peripheral) and CAN. A quick draft schematic is
available at http://www.blacksphere.co.nz/tmp/usbcan_1.pdf
The significant portion of the software development would be
support for the OTG and CAN controllers which I would contribute
to libopenstm32. I will also develop a Linux SocketCAN driver
when the device is working.
If anyone is at all interested, please drop me a comment on my
