[UAVCAN/CAN] Driver for TI TCAN4550 #14
Description
Many popular MCUs lack built-in CAN FD-capable controllers, which limits the uptake of CAN FD in new products. There is an interesting IC that could help new hardware revisions or new designs adopt CAN FD without having to port an existing codebase to a new platform: TI TCAN4550 -- a single-chip CAN FD controller with a built-in 5 Mbps transceiver interfaced with the MCU via SPI:
It is also appealing price-wise, being available from DigiKey for $1.5 @ 1k pcs, which is comparable to a regular standalone CAN transceiver.
This is a very promising chip and it would be nice to have portable and reusable drivers for it here.
