# 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.
@ -8,6 +10,13 @@ To compile the firmware, you can run `make`.
To upload the firmware to an Arduino, run `make flash`.
