基于单片机的智能灯光设计电路，愿与大家共同交流(MCU-based intelligent lighting design circuit, and we would like to exchange)

TM1652 是一款LED（发光二极管、数码管、点阵屏）驱动控制专用芯片，内部集成了数字通讯电路、 解码电路、数据锁存器、震荡器、LED驱动电路。通讯方式采用异步串口通信（UART）协议，因芯片只 接收单片机发来的数据，仅需要单片机的一个TX端口发送数据给芯片即可，实现单线通讯；在显示驱动 方面，芯片采用动态扫描方式，两种显示模式可选，8级段驱动电流可调，16级位占空比可调；TM1652 内置消隐处理优化电路。(TM1652 is an LED (light-emitting diode, LED, dot-matrix screen) driver control ASIC, integrated digital communications circuits, Decoding circuit, data latch, oscillator, LED driver circuit. Communication using asynchronous serial communication (UART) protocol, because the chip only MCU receives data sent only need a microcontroller TX port to send data to the chip can achieve single-wire communication the display driver Aspects, chip dynamic scan mode, two display modes, 8 segment drive current is adjustable, 16-bit adjustable duty cycle TM1652 Built-in blanking processing optimization circuit.)

官方的卡尔曼滤波算法，二维,角度融合算法(The official Kalman filter, two-dimensional)

利用STM32F103的两个通用定时器产生SPWM波输出。(Two universal timers of STM32F103 are used to generate SPWM wave output.)

假设P1.0口为发光二极管（共阴），其通过按键来控制是否开启(Suppose that the P1.0 port is a light emitting diode (common negative), which controls whether to turn on or not by pressing a button.)
