CRYPTO μMiner

A solo crypto miner for a little T-Display S3 (ESP32).

(Node: This was inspired by other miner software like: https://github.com/valerio-vaccaro/HAN)

Overview

Assuming you have a CRYPTO μMiner with an already installed software image.
(In case you want to build and upload a new image refer to the Flash section below.)

Connect to the network

1. Boot the CRYPTO μMiner by connecting a USB-C power supply.

2. The CRYPTO μMiner now tries to connect with a Wi-Fi network.
   If this fails (typically because there is no correct Wi-Fi access data being configured), it will change to the "-CONNECTING-" screen where a QR-code with its access point details is displayed.
   Connect with your smartphone to the uMINER Wi-Fi access point:
   

3. Press the [Configure WiFi] button and enter the SSID and password of your Wi-Fi.
   After saving the CRYPTO μMiner is going to restart and connect with your Wi-Fi.

Select Screens

After each start and successful connection with the network, the CRYPTO μMiner is going to show the "-ONLINE-" mining screen.
By applying a short press to the SCREEN button you can cycle to the screens:

• ONLINE
• CLOCK
• NETWORK
• STATUS

Configure the display

The display can be changed using the DISPLAY button:

• Single press
  Toggle the display on/off
• Long press
  Adjust the display backlight brightness
• Double press
  Rotate the the display by 180° degrees

Force Setup

To force the CRYPTO μMiner to switch into the "-CONNECTING-" screen, you would need to press reset button and then keep the SCREEN button pressed (while in the initial "-OFFLINE-" screen) until it switches into the "-CONNECTING-" screen.
