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.
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.
I found some time this weekend to start assembly of my Chipstomp’s.
The digital side of the Chipstomp is assembled and up and running
My PCBs arrived from DirtyPCB.com today and they look pretty good! I’m hoping to find a bit of time this weekend to assemble one. Lets hope that I got my footprints right…

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.

Yet another guitar effects pedal
Here’s something I’ve been working on for a while. It’s a digital guitar effects processor based on a PIC32MX. Continue reading
