Build website

To build the website for viewing and OTA updates open the Angular project found in

ESP-Miner\main\http_server\axe-os

Then install dependencies and build.

npm i
npm run build

When the esp-idf project is built it will bundle the website in www.bin

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Run Unit tests

The unit tests for the project use the unity test framework and currently require actual esp32 hardware to run.

They are located at https://github.com/johnny9/esp-miner/tree/master/components/stratum/test

cd ./test/
idf.py set-target esp32s3
idf.py -p PORT flash monitor
