Two-degree-of-freedom pan-tilt robot control platform

This work, titled "Two Degrees of Freedom Pan-Tilt Robot Control Platform", implements a complete pan-tilt robot control platform. The system uses motion sensors as control handles to control the movement of the robot, and cooperates with the OLED screen to display the system's Current status. Using the control handle, you can control the movement of the vertical axis servo through forward and backward movements, and control the movement of the horizontal axis servo through rotation operations, thereby realizing two degrees of freedom control of the robot.

BLDC driver based on GD32

A brushless motor may seem like a simple thing, but it can be very complex to drive. As an electronics enthusiast, I just tried it with the spirit of a newborn calf who is not afraid of tigers. It doesn't take long either. So the things I make only have one look, and I hope you won’t criticize them.
