PIO CANbus & ODBII on a Pico ?

Post by DWiskow » Wed Feb 10, 2021 5:49 pm

Does anybody know if it is possible to implement CANbus using the RD2040 PIO? . . . clearly a CANbus transceiver such as a SN65HVD230 would be required to handle the differential voltage, but the question is can the PIO effectively replace the need for a CANbus controller such as the MCP2515 (and with the advantage of full DMA support)?
