说明：  MPU6050是我们常用的六轴空间位置处理芯片，次文档使用卡尔曼滤波的方式使数据更加的准确(MPU6050 is our commonly used six-axis spatial position processing chip. Kalman filter is used in sub-documents to make the data more accurate.)

TFT3.5触摸彩屏 校正,C51单片机程序(TFT3.5 touch color correction, C51 MCU program)

基于stm32的485编程范例，RS-485采用平衡发送和差分接收，因此具有抑制共模干扰的能力。(Based on the 485 programming paradigm of stm32, RS-485 uses balanced transmission and differential reception, so it has the ability to suppress common mode interference.)
