# Delta M0

## What is this?

Delta M0 is a **basic, compact scientific calculator** based on an STM32F0

microcontroller.

It has a matrix of 4 columns and 5 rows of buttons, a small OLED display, a power switch on the side, and a 6-pin serial programming header on the top.](img/front.jpg) | ![The back of the Delta M0. It has a JST battery connector on the top, a battery controller IC, an STM32 microcontroller, and some supporting passive components.](img/back.jpg)

## How well does it work?

It does _work_, but you probably don't want to use it as an actual calculator

yet. The software is really lacking.

## Project structure

This is based off the

[libopencm3 template](https://github.com/libopencm3/libopencm3-template).

  - `my-project` contains the C code for the firmware.

  - `test` is a small set of unit tests which you can run with `./test/run`.

  - `hardware` contains the KiCad files for the PCB. 

# Building

Make sure you clone with `--recurse-submodules`!

Then:

```

make -C libopencm3

make -C my-project

```
