README
README.mdElectronic tracer
The "driver-v1" folder
- Use it for physical tracer board, version 1.
- Prerequisites:
libudev1andg++installed (sudo apt-get install libudev1 build-essential). - Driver based on Kerry Wong's library (https://github.com/kerrydwong/MCP2210-Library).
- To build the driver-application, run
cd driver-v1; make. It will generate thetracerbinary, which should be run as root (or with thesetuidbit set).
The "driver-mock" folder
- Use it for local testing, without a tracer board. It's a dummy data source.
- Prerequisites:
g++installed. - To build it, run
cd driver-mock; make. It will generate thetracerbinary.
The "frontend" directory
- Frontend done using electron.js and apex charts.
- It uses
npm. - To build, run
npm install. - To run, copy the
tracerbinary (from eitherdriver-v1ordriver-mockdirectories), and then runnpm start. - Tested with node 14.x.
The driver-v1 requires setuid permissions. See the snippet below.
cd frontend
cp ../driver-v1/tracer .
sudo chown root tracer
sudo chmod +s tracer
npm startThe "board" directory
- Contains the kicad project used for manufacturing the first iteration of the board.

Questions
How big is the Tracer PCB?
It measures 89.5 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tracer use?
26 parts, built around the MCP2210-I/MQ, MCP3204-CI/P, MCP4921-E/P and L7805. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Tracer KiCad files?
From the adrians/tracer repository on GitHub, at the commit this page was made from: the board is board/v1/tracer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tracer design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
