Note that audioinjector uses some GPIO pins that are already used by Zynthian default configuration (the last statement is incorrect and amended in another comment below …). Althought you have no rotary encoders in your setup, Zynthian UI will try to read from it. I’ve fixed this in the last software version, so you should try it:
When you have correctly updated the UI software, you should edit the config file “zynthian_gui_config.py” and configure the GPIO layout as “dummies”:
hw_version="DUMMIES"
This will prevent the zyncoder library to try to configure and read the rotary encoders & switches.
Whew, you almost made me nervous. I have the audioinjector working just fine for output, but I’m still waiting for a cheap Chinese lcd to arrive. The kids don’t really appreciate when I’m using the TV as hdmi display. In the meantime I’m trying my luck with toner transfer for the pcb’s. I haven’t etched a board since 8th grade
Normally, this step is not needed and could break something, specially MIDI-IN, but if it worked, OK, it’s better to have an updated kernel and firmware
This is not needed, but. It’s intended for using an extra USB card, but i think it wouldn’t be needed never more.
Better to ignore. I will remove this function in the next release.
To be honest I am trying to replicate and take down notes but it doesn’t
work anymore I think my daq+ soundcard gets in the way now that I received
it… it’s a mess… lost a few hours already…
Hey all,
So i have a RapsberryPi official 7 inch display and an audioinjector. And I found that if I connect it to the SPI interface the audio injector stops working, but if I only connect the ribbon cable and the power it works. Strangely enough the touch screen also works.
