aivcho 0 Posted August 6 Maybe someone tried to use this RS485 CAN Hat on Asus tinkerboard 2S ? HAT link: https://www.waveshare.com/wiki/RS485_CAN_HAT_(B) It needs two overlays. overlay=mcp2515-can0,oscillator=16000000,interrupt=25,,spimaxfrequency=1000000 overlay=sc16is752-spi1,int_pin=24 found one by default - mcp2515-can0 sc16is752 needs to be written. Also CAN needs to activated in kernel. Share this post Link to post Share on other sites
