Real-Time Duino-Coin Mining Stats with ESP8266 and TZT 1.77 Screen
Hey Science Enthusiasts! Today, we’re diving into an exciting project: integrating a TZT 1.77 inch color screen with an ESP8266 NodeMCU to display real-time statistics from your Duino-Coin mining operation. This enhancement allows you to visually monitor vital metrics such as hash rate, difficulty, shares, and more directly from your device. The primary mining code can be downloaded from DuinoCoin.com, and we’ll be adding custom display functionality to it. Let’s get started!
Download the mining code
To begin setting up your mining display, you’ll first need to download the official Duino-Coin mining code. Visit the Duino-Coin website, and click on the “Get Started” button. This will guide you through the process of creating an account if you haven’t already done so. Once your account is set up, navigate to the ‘Miners’ section of the website. Here, you’ll find various resources and the latest versions of mining software tailored for different platforms and devices. Download the ESP8266 mining code to your computer, as this will serve as the foundation for integrating the TZT 1.77 inch color screen with real-time mining statistics.
Materials You'll Need:
- ESP8266 NodeMCU: The microcontroller that will manage our mining and display operations.
- TZT 1.77 inch Color Screen (ST7735 Driver): For displaying the mining statistics.
- Jumper Wires: To connect the screen to the ESP8266.
- USB Cable: For programming the ESP8266.
Step 1: Connect the Hardware
First, connect the TZT 1.77 inch color screen to the ESP8266 NodeMCU:
- VCC should be connected to 3.3V on the ESP8266 NodeMCU.
- GND should be properly connected to a ground pin on the NodeMCU.
- SCL (TFT_SCLK) should be connected to D5 on the NodeMCU.
- SDA (TFT_MOSI) should be connected to D7 on the NodeMCU.
- RES (TFT_RST) should be connected to D4 on the NodeMCU.
- DC (TFT_DC) should be connected to D1 on the NodeMCU.
- CS (TFT_CS) should be connected to D2 on the NodeMCU.
Select)
2. Check the Power Supply
Make sure that the display’s VCC is connected to a 3.3V supply from the ESP8266. Some displays are 5V tolerant, but check your display’s specifications to avoid supplying the wrong voltage.
3. Prepare Additional Display Modules
Add DisplayModule.cpp and DisplayModule.h to your project directory. These files will manage the display logic and should be in the same folder as your main Arduino sketch.
4 . Install Required Libraries
Install the necessary libraries to interface with the display:
- Open Arduino IDE, go to Sketch > Include Library > Manage Libraries…
- Search for and install Adafruit ST7735 and Adafruit GFX libraries.
Include the Display Module and Libraries in your Arduino sketch:
Initialize the Display in the setup() function:
Update the Display with Mining Statistics in the loop() function:
Step 5. Compile and Upload
- Connect your ESP8266 NodeMCU to the computer using a USB cable.
- In the Arduino IDE, select the correct board under Tools > Board and the correct COM port under Tools > Port.
- Upload the modified sketch to your ESP8266.
Step 6. Monitor Your Miner
Once the code is uploaded:
- The screen will light up and begin displaying the mining statistics.
- Watch as your mining performance data is dynamically updated, providing a visual insight into your Duino-Coin mining activities.
Congratulations!
You’ve now successfully integrated a colorful display into your Duino-Coin mining setup with an ESP8266 NodeMCU. This project not only boosts your hardware programming skills but also enhances your understanding of cryptocurrency mining dynamics. Enjoy monitoring your mining stats and happy mining!
