10A four-channel brushless ESC based on STC15 (verified)

Overview

Modified from the ESC example on the STC official website:
Circuit:
1. Increase the number of channels, the circuit board layout is more compact, and it is suitable for the small cabin space of the Flying Drone
2. Replace the 7805 in the original circuit with the LM2596 switching power supply circuit, which solves the heating problem at 3S and improves the power efficiency
Software:
1. Improved the response speed
2. Added power-on music and protection of the throttle not being 0 when powering on
Provided an improved Keil C program

Please ask the master, is my design idea correct?
Now I want to use msp430 g2553 to control 3 servos (the kind used for robotic arms). The parameters of the servos are 900usec~2100usec for the rotation angle and 700~2300usec for the pwm width. I need
