GymPal
A simple device for recording gym sessions, using AVR.
The GymPal is a lightweight piece of hardware with built-in storage, time-keeping, display, and controls, to allow you to record exercise metrics on-the-fly in a satisfying, tactile way.
Development
The software for this system is developed in C, using avr-libc, and the build toolchain is managed by make, using avr-gcc and avr-dude to upload firmware to the Atmega328p microcontroller.
sudo apt install gcc-avr
sudo apt install avr-libc
sudo apt install avrdude
After cloning this repository, you must first compile the build script with ./prepare-build-tools.d. Then, you can run ./build <command> to run various build commands. See ./build help for more information.
