Products & Technology Raspberry Pi
#1

I really need 4-Channel CAN FD module.

I already bought 2EA 2-Channel CAN-BUS(FD) Shield for Raspberry Pi.
One is working well (SPI0)
But the other one is not working (SPI1)

  • Using default SPI1 MISO/MOSI,SCLK,CE0,CE1
  • Interrupt pin : GPIO22/23

If you have 2xMCP2518FD-spi1-overlay.dts please share it to me.

Is it possible to make 4-Channel CAN with 2EA 2-Channel CAN-BUS(FD) Shields?

One is connected with SPI.
Another is connected with SPI1.

I really want to 4 CH CAN FD Device.
