+CH224Q/CH224A are USB PD fast charging protocol sink chips supporting USB PD3.2, with a maximum PD3.2 EPR power of 140W. They support single resistor configuration, I/O level configuration, and I2C configuration. The protocol handshake status and current PD voltage/current rating can be read via the I2C interface. The chip has a built-in high-voltage LDO, low static power consumption, high integration, and simplified external circuitry. It also integrates output voltage detection and overvoltage protection, making it widely applicable for expanding high-power input in various electronic devices such as wireless chargers, small appliances, lithium battery power tools, and more.

+Since ST-LINK/V2, all ST-LINK boards have a LED labeled "COM" (on the case or PCB).
71
+
72
+Regardless of the connection type, this LED indicates the ST-LINK status:
73
+- LED flashing red: Performing initial USB enumeration with the PC.
74
+- LED solid red: Communication between PC and ST-LINK established (enumeration complete).
75
+- LED alternately flashing green and red: Data is being exchanged between the target and the PC.
76
+- LED solid green: Last communication was successful.
77
+- LED solid orange: Communication with the target via ST-LINK failed.
78
+
79
+In this project, following the design of the Pandora development board which integrates ST-LINK V2-1, a single red LED is used to replace the original red-green dual-color COM indicator. Therefore, this project also uses a single red LED for the COM indicator.

116
+## Test and Debug
117
+
118
+- Test programming function: Use Keil-MDK to download the program successfully, indicating programming works correctly.
119
+- Test debug function: Use Keil-MDK for debugging, and if debugging works, the debug function is normal.
120
+- Test USB disk drag-and-drop programming: Generate a bin file (see bin file generation method), drag the bin file into the ST-Link simulated USB disk, and if programming succeeds, the virtual USB disk function is normal.
121
+- Test serial communication: Connect TX and RX of ST-LINK V2-1 with DuPont wires, open a serial assistant, send data, and if the received data matches, the serial communication is normal.

9
+USB Power Delivery (USB PD) is a fast charging technology that allows devices to negotiate higher power levels over a USB connection.
10
+
11
+Unlike standard USB charging, which is limited to lower voltages and currents, USB PD supports up to 100W (20V, 5A) and dynamically adjusts voltage and current based on device needs.
12
+
13
+This enables rapid charging for smartphones, laptops, and other electronics, while ensuring safety and compatibility. USB PD is commonly used in modern USB-C devices for efficient and flexible charging.
14
+
15
+### specifications:
16
+
17
+- USB PD supports multiple voltage levels: 5V, 9V, 15V, and 20V.
18
+- Current can range from 0.5A up to 5A, depending on the device and cable quality.
19
+- The maximum power output is 100W (20V × 5A).
20
+- Devices negotiate the required voltage and current using a communication protocol over the USB-C connector.
21
+- USB PD allows for bi-directional power flow, meaning either device can supply power.
22
+- Cables must be electronically marked to safely deliver higher currents (above 3A).
23
+- USB PD is backward compatible with standard USB charging but offers much faster charging for supported devices.

+## How USB Type-C 12V Fast Charging Trigger Works
13
+
14
+A USB Type-C 12V fast charging trigger is a small device or circuit that negotiates with a USB Type-C power source (such as a charger or power bank) to output 12V instead of the default 5V. This is done using the USB Power Delivery (PD) protocol.
15
+
16
+### Working Principle
17
+
18
+1. **Connection & Communication**: The trigger connects to the USB Type-C port and communicates with the charger using the PD protocol over the CC (Configuration Channel) pins.
19
+2. **Voltage Request**: It sends a request for 12V output (sometimes specifying the desired current, e.g., 1.5A or 3A).
20
+3. **Charger Response**: If the charger supports 12V PD output, it switches its output to 12V.
21
+4. **Power Delivery**: The trigger then provides this 12V to the connected device or circuit.
22
+
23
+### Applications
24
+
25
+- Powering devices that require 12V from USB Type-C chargers (DIY electronics, routers, etc.)
26
+- Avoids the need for a dedicated 12V adapter
27
+- Used in projects and gadgets needing higher voltage from USB-C
28
+
29
+### Note
30
+
31
+The trigger automatically handles the PD negotiation, making it easy to use with compatible

+Electronic ink screens, also known as e-paper, commonly use "microcapsule electrophoretic display" technology (EPD). The basic principle is that charged nanoparticles suspended in liquid migrate under the influence of an electric field. Electronic ink is coated onto a layer of plastic film, which is then laminated with a thin-film transistor (TFT) circuit. The pixel pattern is formed by controlling the drive IC.
9
+
10
+Electronic ink consists of millions of microcapsules, each about the diameter of a human hair. Each microcapsule contains electrophoretic particles—negatively charged white particles and positively charged black particles—suspended in a transparent liquid.
11
+
12
+Using the principle of attraction between positive and negative charges, when the electric field is applied, the corresponding black or white particles move to the top of the microcapsule, allowing the user to see white or black in that area.
13
+
14
+![](EDP-1.gif)
15
+
16
+Most common e-paper is black and white. Electronic price tags also use a type of three-color e-ink screen, which operates similarly to the two-color system. By applying different voltages, different colored particles move to the top layer, allowing different colors to be seen.

25
+## Advantages and Applications
26
+
27
+E-paper screens are easy to read: e-paper displays rely on reflecting ambient light to show images, giving them a print-like effect similar to paper.
28
+
29
+Lightweight and flexible: Due to their simple structure and the fact that e-paper is based on soft plastic film material, they are naturally flexible and bendable, and can be cut into various shapes as needed.
30
+
31
+Energy-saving: When displaying static images, e-paper consumes no power at all. Even if all power is disconnected, the e-paper display can still retain the last image.
32
+
33
+For example, the smart card below uses e-paper technology and can display the balance.
34
+
35
+![](2025-08-19-15-20-54.png)
36
+
37
+There is also this type of NFC passive smart tag, which can refresh its display content via a mobile phone's NFC. It can be used as an electronic pet tag, electronic luggage tag, to display payment QR codes in stores, or to show a contact number for moving a car.
