# 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](https://www.nongnu.org/avr-libc/), and the build toolchain is managed by make, using [avr-gcc](https://linux.die.net/man/1/avr-gcc) and [avr-dude](https://github.com/avrdudes/avrdude) to upload firmware to the Atmega328p microcontroller.
|
|
|
|
To compile the firmware, you can run `make`.
|
|
|
|
To upload the firmware to an Arduino, run `make flash`.
