This project is a barebones altimeter for use in the freshers rocket challenge. The below instructions are specific to Linux systems only.
Setting up the Repositiory
- Setup the repository using the following commands:
$ git clone https://github.com/cuspaceflight/altimeter.git
$ cd altimeter
$ git submodule update --init
$ cd ChibiOS
$ git checkout stable_16.1.x- To succesfully compile firmware you will need to install gcc:
$ sudo apt-get install gcc-arm-none-eabi- Test the installation by compiling the firmware template:
$ cd ../firmware
$ makeAnalysing Log Files
-
Copy the file "log_0000x.bin" you wish to decode into the altimeter/logs directory
-
From the terminal run:
$ python3 log_file_parser.py log_0000x.binThe output will print directly to the terminal window.
Making Firmware Changes
This will be explained in depth in the sessions, however the files which you will want to modify (status.c, measurements.c and logging.c) can be found in the altimeter/firmware directory.
Compile using the command:
$ makeIf successful something similar to the below should appear in the terminal window:
...

Questions
How big is the Panel altimeter PCB?
It measures 93 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel altimeter use?
208 parts, built around the MS5611-01BA03. 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 Panel altimeter KiCad files?
From the cuspaceflight/altimeter repository on GitHub, at the commit this page was made from: the board is pcb/panel/panel_altimeter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel altimeter design in my own project?
Its repository states no licence, so its author keeps all rights: ask cuspaceflight before reusing the design.
