Difference with pcan_cantact

It looks like fd frames are also not supported in this firmware.
So what is the difference with this firmware https://github.com/moonglow/pcan_cantact? The latter one also supports pcan-view.

Hi !
Some answer was already given here #4 , but i will try to explain more.
So firmware is really supports CANFD frames, all needed protocol handling and so on are implemented and well tested. Hardware ( STM32F4xx ) physically can't send/receive FD frame due bxCAN does not support them. PCAN CANtact is 1 channel basic CAN adapter it was made as alternative firmware for very popular CAN hardware ( CANable, CANtact and Entreé ), PCAN PRO is 2 channel CAN + 2 channel LIN adapter, PCAN PRO FD - same as PRO but supports FDCAN extension. All of them uses three different USB level protocol implementation so it was a cool thing to implement them all. Another thing, i select my base hardware as most cheapest possible, to be sure what many peoples can DIY your own CAN adapter. Anyone can add CANFD to current implementation as example by creating custom pcanpro_can.c and connect something like MCP2517 via SPI to board or port my firmware to something what already has builtin FDCAN hardware such STM32G4xx series.
