PowerV_Lite

Project Overview:
 
 This project is a fast-charging voltage regulator board implemented using the STM32G431CBU6 as the main control unit and an external FUSB302 PD Phy interface. It supports protocols such as PD, QC, UFCS, and AFC. Users can write their own code to implement more proprietary protocols.
 
Known Bugs
 
: 1. Incorrect component U22 model: should be ME6239A33MG
. 2. The fuses used on the D+, D-, and CC pins should be 0.05A.
3. The Zener diode used on the CC pin has a large leakage current, which will pull down the CC pin level, causing some adapters to malfunction. Removing the fuse and Zener diode on the CC pin sampling point will solve the problem.
 
Operation Method :
 
This device supports both button and serial port command voltage regulation.
 
1. When using buttons to adjust voltage, long press to enter the corresponding protocol. After entering the protocol, the corresponding indicator light will illuminate. Single-click to adjust the corresponding voltage. Holding down the Shift key and then single-clicking other buttons will perform voltage fine-tuning.
 



Long press to
enter the corresponding protocol, single-click to adjust to the corresponding voltage, Shift + single-click for voltage fine-tuning . 2. When using serial port commands to adjust voltage , the command format must be followed. Specific command documentation is yet to be completed . Host computer: When using the device for serial port voltage adjustment, the provided host computer can be used. The source code and download address are: https://gitee.com/ospanic/PowerView. Select the corresponding serial port and open it. After opening, waveform upload will be enabled. If you can see the waveform, the communication is normal. Clicking the protocol above will enter the corresponding protocol operation page. Under the PD protocol, clicking "handshake" will disconnect the Rd resistor and then reconnect it, receive the Cap sent by the Source, respond with GoodCRC, and request 5V. Double-clicking the corresponding range will adjust the voltage. You can also send any custom PD message. Other protocol operations are similar. ... Indicator lights: The device has a row of voltage indicator lights to indicate the current VBUS voltage. Source code: https://gitee.com/ospanic/PowerV_G4
