[Schrödinger’s Rabbit Paper] ESC based on EFM8 microcontroller

Overview

! ! ! This board does not have a bus filter capacitor. Be sure to add an electrolytic capacitor when using it, otherwise the tube will explode! ! !

This solution comes from https://oshwhub.com/CLZ1/ji-yublheli-diesc.
Using the open source BLHeli firmware
ESC principle and firmware flashing method, you can refer to the above project.

I drew the PCB with the following three purposes:
1. [Be cute and cute] [Guotian]: It means that the size of the PCB should be as small as possible
2. [Obsessive-compulsive disorder friendly]: Align and align! If not aligned, you will die!
3. [The Stubbornness of 0805]: I am blind and only solder devices above 0805 (the
design goal is to make a small-sized, low-power 12V ESC with single-sided components
and finally achieve a PCB area of 26*28mm. If it is opened in half holes, and remove the upper and lower redundancy, it can be reduced to 25*25mm, which is suitable for the module to be attached to other PCBs. For

How to make the cursor return to its original position after input?
In WinCE 5.0, I made a scanning program. After scanning, the result is output to the text editing position where the cursor is located. Input can be made in the position outside this program. How can
What's wrong with the initialization routine of the serial port TX0 interrupt?
Programming goal: Use the AVR128 microcontroller to let TX0 continuously send data 0X33 at a baud rate of 9600. The current problem is that the sentence UDR0 = 0x00 must be added to the initialization
Please tell me how to do it...
The A/D is sampled at a sampling frequency of 1KHz, and the sampling channel number and sampling results are displayed on the LCD screen. Use the K1 and K2 buttons to switch the sampling channels. Pre
