Hyperion + LED APA102



  • Hello Recalboxers,

    I want to add some ambilight to my recalbox. I use the APA102 LEDs and set it up like this (from the hyperion tutorial):
    Sketch

    Unfortunately it doesn't work. Now im searching for the problem.
    I checked the wiring a view times and couldn't find a mistake.

    Maybe I made a mistake when setting up Recalbox for Hyperion. This is what i've done so far:

    • update to recalbox 17.11.10.2
    • copy my hyperion.config.json to /recalbox/share/system/config/hyperion/hyperion.config.json
    • enable hyperion in recalbox.conf

    3/4 of the LED stripe lights up when starting the Pi. But then the LEDs do nothing. Seems to me like the LEDs don't get a signal from the DI / CI GPIOs. When I checked the Hyperion status via ssh I get the following Error:
    0_1510788278522_hyperion_error.PNG

    Does anyone have an idea what the problem might be?

    Thanks

    Hi,

    could you add the line dtparam=spi=on in your config.txt file please:

    mount -o remount,rw /boot && echo 'dtparam=spi=on' >> /boot/config.txt

    and reboot
