Firmware

The eSpa firmware is available for download from the eSpa GitHub repository. It is a Platform.io project, which makes it really easy to build and upload to your hardware, but there are multiple ways you can build and flash the firmware to your device.

Using a GitHub release

You can download a release from the GitHub repository for this project, and then flash it to your eSpa by connecting it to your computer with a USB cable. You can find the latest release on the releases page. Once you've download the firmware, you can flash it to your eSpa by following the instructions for web-based flashing.

Using Platform.io GUI

Follow these steps to build the firmware:

1. Download and install Platform.io.
2. Clone the eSpa repository to your computer.
3. Open the project in Platform.io.
4. Determine your build environment:
   1. In platform.io, look at the platformio.ini file. There are different environments available for different hardware. There is esp32dev for the ESP32 development board, and spa-control-pcb for the custom eSpa control board. You can learn more about hardware options in the hardware section.
5. Connect your hardware to your computer.
6. Choose 'upload and monitor' in Platform.io to build and upload the firmware to your hardware. You should see the firmware being uploaded and the serial monitor starting. If this completes successfully, you should start to see debug output in the terminal window from the ESP32 chip.
