Touch Desktop

Overview

The project mainly uses the TTP223 touch chip. When the chip's induction coil senses an object, the chip's 3rd pin will output a signal to control the conduction of the MOS tube, thereby turning on the LED light. The idea of this project can make a touch desktop, but it requires multiple boards to be spliced together, or a large board to be produced. This touch desktop uses two layers of boards. I use an aluminum substrate for the bottom layer to facilitate the heat dissipation of the LED light. The shape of the top layer can also be designed by yourself. The top and bottom plate files are all here, but I don't know how to layout this.

stm32f4discovery serial port garbled code problem
I have changed it according to the instructions in many places, but it is still garbled. The system_stm32f4xx.h, conf.h, and f4xx.h have all been changed to 8M. I don't know why it still doesn't work.
Can the bkp register be used as data storage?
If I don't have much data, can I save it to the bkp register (keep its data through the battery)?Because the bkp space of the large-capacity device has 42 16-bit spaces, that is, 84B
What is the impedance shown to the outside during resonance?
What is the impedance shown to the outside during resonance? How to calculate it? Is it related to the Q value?
What does this mean? Thank you.
