Arduino单片机开发笔记2-7,希望大家都看看(Arduino microcontroller development notes 2-7, we want everyone to see)

在下的毕业设计，　　　本题要求设计一个直流电机控制系统。在设计中，采用国产单片机中目前比较新式的STC12C5A60S2作为整个控制系统的控制电路的核心，因为STC12C5A60S2内部有PCA模块，可以产生PWM波形；采用带中断的独立式键盘作为命令的输入，每当按键时蜂鸣器响；配以LCD12864显示实现对带光码盘的直流电动机转速参数的测量、显示和控制。LMD18200驱动模块内部是H型驱动电路，驱动能力较强，完成电机正反转以及速度的控制。为优化直流电机的响应，采用PID反馈，实现闭环控制。(Graduation in the next, and that the requirements to design a DC motor control system. In the design, the use of the relatively new domestic microcontroller as a control circuit of STC12C5A60S2 entire control system core, because STC12C5A60S2 internal PCA module can generate PWM waveforms using a separate keyboard with interrupt input as a command, whenever the button When the buzzer sounds accompanied LCD12864 display realize the measurement of the optical encoder with DC motor speed parameters, display and control. LMD18200 internal drive module is H-drive circuit, driving ability, and the speed of completion of the motor reversing control. In order to optimize the response of DC motor, using PID feedback, closed loop control.)

树莓派SPI转CAN，利用MCP2515模块，进行CAN通讯，分开两个.py代码：TX（发送）和RX（接收）的，具体的GPIO口要在代码里自行修改为实际的PI通讯引脚。(Raspberry Pi SPI to CAN, using MCP2515 module, for CAN communication, separate two .py codes: TX (send) and RX (receive), the specific GPIO port should be modified in the code to the actual PI communication pin.)

说明：  使用SONIX的IC來驅動PWM功能、T0T1的計數器(Using SONIX IC to drive PWM function and T0T1 counter)

说明：  测脉宽，基于STC15W单片机的测试要在1.3管脚加一个脉冲然后通过OLED 屏幕显示(Pulse width measurement)
