Is it possible for the Klipper Devs to add a UART to Can Bridge config for STMGOB1 boards? I used to use UART between my PI and SKRminie3v3 until I added an EBB42 canbus toolhead to my printer. As my Pi is a Zero2W I was hoping to leave the USB port available for another use, but now I am using it in USB to Can bridge with my SKR. Are the Klipper gods interested or able to implement another Can bridge mode?
I don’t believe the MCU supports this, and even if it did the UART interface is too slow.
Interesting. I was under the impression that UART is faster than USB. I guess I’ll have to grab a USB hat or CAN hat for my pi.
Don’t get a CAN hat. They’re no longer recommended as too many people have had problems getting them to work reliably.
Good to know! Thanks!
Standard CAN hats, yes, but FDCAN hats work with no issues. These can operate at CAN 2.0 and FDCAN; when and if Klipper supports FDCAN, it would be just a change in settings for your RPi and CAN device’s firmware. Well probably not FDCAN due to licensing cost.
Probably will not happen, since FDCAN is protected by Bosch patents
