jayrope Is the mini-mux branch planned to enter the master at some point soon?
Someone will have to test that it works first! Once it's confirmed it works it shouldn't be complicated to mainline it, although it will probably require to manually edit one lime in the file to enable it.
jayrope And surely, as a 4051 only gets us 8 channels muxed, this branch is about 8-channel muxing or is it working independently from the chip used for muxing?
The code uses some of the pins on BelaMini to drive a binary counter, the same way it would happen on a Bela when using the multiplexer capelet. Then it's up to you to connect as many 4051 as you need, possibly copying the relevant parts of the schematics of the multiplexer capelet
