# ColorChord running on an STM32F303
|
||||
|
||||
|
||||
## Step 1: Get the necessiary build enivronment
|
||||
|
||||
```
|
||||
sudo apt-get install build-essential gcc-arm-none-eabi libnewlib-arm-none-eabi openocd
|
||||
```
|
||||
|
||||
## Step 2: Build
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
Note: Step 2 being called "build" is a misnomer. If you have your board plugged in, it will also flash.
