GL850G

Overview

Expander designed based on GL850G four-way USB2.0.
The input uses a USB male connector (the male connector seems inconvenient in actual use, and can be changed to a female connector later), and the output uses two two-way USB2.0 female connectors stacked.
Most of the entire board is packaged in 0805 (two are packaged in 0603), which is convenient for personal welding.
The board has four M3 slots, so you can design and install the casing yourself.

How to release the first four bytes of ucos memory, but the following data still exists
I would like to ask how to release the first four bytes of ucos memory, but the subsequent data still exists. When waiting to apply for the memory block again to write data, the data length is smaller
The microcontroller reads the USB mouse data and displays the coordinates
I want to use a single chip microcomputer to read the data of the mouse. Has anyone done this before? Can you please let me have a look at the program? Thank you.
Which great god can answer this, I will be very grateful!
