Raspberry Pi Voice HAT LED not working

  • kk

    Hello,

    I'm using the Voice HAT Voice_HAT

    Speaker and Micro are working with seeespeeker Software. 
    (Raspberry 3, Raspberry Pi 3A+, Buster)

    LEDs are not working. Green LED is permanently ON.

    I tried the Voice_HAT_Software

        sudo python pixels.py

    -> No LED [Software gives no Error, added print("something") after pixels.wakeup() ]
    Also tried other Software, which works with respeaker 4-mic array.

    Same result at friend, who bought same model.

    Help needed.

     

    sincerly

    Kay

    Hi, 

    Thanks.

    1. Do you use other GPIO pins?

    2. Could you provide more details such error snapshot or other photos?

    Regards

    No other GPIOS used. Fresh installed buster.

    Which kind of errors? pixels.py runs and prints whatever I want. SPI is activated.

    I will try to watch syslog and post it later.

    thank you

    Fresh installed:

    • OS Buster (update + dist-upgrade)
    • git 
    • seeed-voicecard
    •  pip, spidev
    • SPI enabled
    • Voice-Hat (download + unzip)

    sudo python pixels.py

    /var/log/syslog:

    spidev spi0.1: zero-length SPI transfer ignored

    And, of cause: NO LED

    @kay koch This board does not use standard GPIO pins. It uses MOSI = GPIO23, SCLK = GPIO24. Documentation is close to non existing, but I found this one that works: https://github.com/u-geek/RaspiVoiceHAT

    I'm using it to create a skill for Mycroft. Not finished yet:
