SUNVOX ASSIGN BUTTON PATCH

I have the buttons soldered to it, but they play no role. I used a 3.2 inch PiTFT from Adafruit ( ). I put a single male header facing up on the ribbon cable in between the existing male connectors that face down. The ribbon cable plugs into the 20 pin connector. I soldered a 20 pin connector to the top of the audio card. I used the spacers that came with the audio card. I used a HiFiBerry Pro DAC+ in the standard way.

Ĭhanges to the image according to the patch below. The SD image is zynthian_gorgona_ (SHA1 37df1cdcea224f680e215b3e18ae28a99c3e9ca1) downloaded from. I used a Raspberry Pi 3 “Machine model: Raspberry Pi 3 Model B Rev 1.2” according to the kernel boot messages (dmesg | grep Rasp). Including, calling out any differences from what I believe is the current canonical build.

I will be as complete as I can be in detailing the build. What follows is the “as built” documentation for this unit.

General unfamiliarity with rPi and wiringPi.

There are at least two conventions for naming GPIO pins.

Fritzing is no substitute for properly prepared schematics.

Small inconsistencies in the build docs.

The chief difficulties I met in building this: Note the absence of the GPIO-ext (MCP23008 and related.) I found two unused GPIO signals on the rPi connector and referenced those in /zynthian/zynthian-ui/zynthian_gui.py rather than pins 7 and 8 on the GPIO-ext connector. On the larger protoboard is the MIDI RxD interface hacked together from available parts.

On the small protoboard are the connections to the GPIO pins. Here is a picture of my just completed zynthian build (calipers for scale.)
