Project Demonstration: After powering on, the motor will automatically reset, and then the screen will display the main menu. The main menu is divided into three columns. The top column displays status information: time, title, and connection information. The middle column displays sensor information. The bottom column displays window mode, current window position, and alarm information (not displayed if no alarm occurs). The four buttons below the main menu are parameter setting, mode selection, window opening button, and window closing button. Pressing the parameter setting button will enter the secondary menu, with the button functions of OK, Back, Previous Page, and Next Page. After selecting the parameter to be set in the second-level menu, press the OK button to enter the second-level sub-menu. The button functions are to switch, save, increase, and decrease.
Remotely control windows and view environmental data via the DianDeng Technology APP. Windows can also be controlled via Bluetooth remote control or voice assistant.
Overall demonstration.
I originally planned to do more, but the recent project proposal took too long, affecting my schedule.
This project uses the Dikuoxing development board, controlling the night light via a relay. A three-pin 2.54" connector is used to connect to an external DHT11 temperature and humidity sensor module, and a six-pin connector is used to connect to an external ESP8266 (powered at 5V here; this module supports 3.3-5V).
The back also includes external pins for a photosensitive sensor, a thermal sensor, a buzzer, Bluetooth, a servo motor, and an XY joystick for future study and research.
If this project is open-sourced, I will upload a video of the process to blbl. Welcome to exchange ideas and learn together.
Project Name: ESP32-Type-C Ammeter (with PD Spoofing Function)
Project Description:
This project is a Type-C ammeter based on the ESP32 microcontroller, using a button and a CH224 chip for PD (Power Delivery) spoofing. It implements PD protocol power management through the Type-C interface, monitors current and voltage in the circuit in real time, and displays the data on a 0.96-inch TFT screen. The project integrates a TI INA226 sensor for high-precision current and voltage acquisition, providing accurate reference for power management of USB devices.
Hardware Components:
ESP32 Microcontroller:
- Model: ESP32S3R8N8
- Provides Wi-Fi and Bluetooth functionality, with rich peripheral interfaces.
- Communicates with the INA226 sensor via I2C and drives the TFT screen via SPI.
TFT Screen:
- Size: 0.96 inches
- Interface: SPI
- Function: Displays parameters such as voltage, current, and power.
TI INA226 Current Sensor:
- Function: Used for accurate measurement of current and voltage.
- Features: Supports I2C communication, built-in 10 milliohm sampling resistor.
USB Type-C Interface:
- Connects devices via the USB-C interface for current and voltage monitoring, and supports PD protocol power management.
CH224 PD Spoofing Chip:
- Function: Triggers the PD protocol, simulating device PD fast charging voltage selection.
- Features: Can be triggered by a button to select different voltage levels, spoofing the device to output a specified voltage (e.g., 5V, 9V, 12V).
Buttons:
- Two physical buttons are designed:
1. Voltage Level Selection: Used to select different voltage levels for the PD fast charging protocol.
2. Display Mode Switching: Used to switch the content displayed on the TFT screen (e.g., display modes for different parameters such as voltage, current, and power).
Working Principle:
Data Acquisition: The INA226 sensor communicates with the ESP32 via I2C to acquire voltage and current data in the circuit in real time.
PD Spoofing Function: Through the PD spoofing function of the CH224 chip, users can select different voltage levels by pressing a button to simulate the device's request for a fast charging power source.
Data Processing: The ESP32 processes the acquired data and displays the current voltage, current, power, and other information in real time on the TFT screen.
Type-C Interface Monitoring: Power and data transmission are handled via the Type-C interface, monitoring the current and voltage passing through this interface.
Project Features:
PD Spoofing Function: Using the CH224 chip, a button allows for PD protocol fast charging voltage selection, enabling users to choose different charging voltages for monitoring.
Button Interaction: Two buttons switch between PD voltage levels and TFT screen display modes, increasing user interaction flexibility.
High-Precision Current and Voltage Monitoring: The TI INA226 sensor ensures high-precision current and voltage measurements.
Real-Time Display: Power, current, and voltage information are intuitively displayed on a 0.96-inch TFT screen.
Application Scenarios:
USB PD Charger Testing: Can be used to test whether USB chargers supporting the PD protocol correctly output the target voltage.
Electronic Device Power Consumption Monitoring: Monitors the power consumption of various PD devices.
Development and Debugging: Suitable for developing and debugging electronic devices requiring PD spoofing functionality, facilitating verification of power consumption performance under different voltages.
By integrating the PD spoofing function, this project not only monitors current and voltage but also has PD protocol voltage selection capabilities, suitable for scenarios requiring fast charging management.

Using LCSC SkyStar as the main controller, an extended version was designed to support the generation of waveforms such as sine waves, square waves, triangle waves, and noise waves of different frequencies.
Output channels: 2 (independently controlled)
; Duty cycle: 0-100%;
Output range: -3.3V to +3.3V.
To optimize cost, parameters such as frequency and duty cycle are all software-controlled. Amplitude is controlled via a PCM5102APW chip. Multiple expansion options are available for ease of use.
Two rotary encoders are used to adjust various parameters, including waveform type, duty cycle, amplitude, and frequency. A 0.96-inch OLED screen displays parameter information. The expansion board provides various output interfaces for convenient use.
