The H20 orange pi boards have on 40 pins GPIO PIN 18 CAN_RX signal. Why do you play with SPI to CAN adapter instead of use built in internal CAN peripheral. Only can transmitter is needed. Why do you involve SPI to convert it later to CAN? By the way usually CAN pins are named as CAN_L and CAN_H why did they called it as CAN_RX? If this was typo were is CAN_TX pin?
