Raspberry pi and RFM69HCW



  • I have Raspberry Pi 4, and RFM69HCW radio module. I use the below code, but I get the following error. Changing the baudrate does not help. Attached you can see the wiring.

    import board
    import busio
    import digitalio
    import adafruit_rfm69
    RADIO_FREQ_MHZ = 433.0
    CS = digitalio.DigitalInOut(board.D8)
    RESET = digitalio.DigitalInOut(board.D5)
    print(board.SCK)
    print(board.MOSI)
    print(board.MISO)
    spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)
    print(spi.frequency)
    rfm69 = adafruit_rfm69.RFM69(spi, CS, RESET, RADIO_FREQ_MHZ,baudrate=100000)#

    Error message:
