ChipStomp – Source code

IMG_0972

A quick update to say that I have released version 1.0 of the source code for the ChipStomp.

I’ve spent a fair bit of time making sure that the source is documented in the areas that are less clear and I have removed all redundant/experimental code in an attempt to avoid confusion with things I haven’t finished yet.  That took a lot longer than I would ever have imagined.

You can find the entire project including the Eagle CAD schematics and Layout up on GitHub.

Chipstomp assembly – Analogue side

Fully assembled and working Chipstomp

Fully assembled and working Chipstomp

It’s done.  I’ve assembled the analogue side of the Chipstomp and finally have a fully working device.  There were no errors to fix this time which was a nice surprise.  Just lots of fiddly 0805 surface mount components to place.

I’ve made a quick video of the project to demonstrate what it can do.

Schematics for the Chipstomp

Here are the schematics for the Chipstomp.
I’ve tried to keep as much compatibility with the original DP32 circuit but I have removed superfluous elements such as the on-board potentiometer and one of the user leds. I’ve also added an additional tactile button, the OLED and resistor mixed Stereo to Mono input/outputs.
Other than that it’s essentially just a joining of the ChipKit DP32 with the Stomp Shield.
