How to build it

Firmware upload
First of all, install PlatformIO with your favourite IDE (i.e. VSCode). Follow this instructions. Also, you may need to install git in your system. source code
Clone the repo
git clone https://github.com/hpsaturn/co2_m5coreink.git
Via IDE (vscode)
Connect the M5CoreInk or compatible board via USB. In Windows 10, drivers are installed automatically. I guess with other OS will be automatically installed too.
Open cloned folder with your PlatformIO IDE and build & upload it. For details please see the documentation, but the process flow is more easy than Arduino IDE flow, but you can also import it to the Arduino IDE if you want.

Via PlatformIO CLI
After the clone, enter to directory and you can build and upload the current firmware from CLI:
pio run --target upload
