用于STM32 的简单MODBUS从协议(MODBUS for STM32MCU,very usefull)

说明：  非编码键盘是利用MCS—51单片机内部的定时/计数器、中断系统、以及外围的按键和LED数码管显示等部件，设计一个单片机非编码矩阵键盘。并能通过按键实现显示0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F。(The keyboard is used non-coding MCS-51 microcontroller internal timer/counter, interrupt system and the external buttons and LED digital display and other components, to design a single chip non-coding matrix keyboard. And pass the key to achieve display 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F.)

stm32液晶屏代码，通过按键使液晶屏显示的内容上下左右移动(Stm32 LCD code, through the buttons to make the content of the LCD display top to bottom and move around)

通过定时器控制pwm输出，进而控制电机舵机的转动。(The output of PWM is controlled by a timer, and then the rotation of the motor steering gear is controlled.)

CCS所有功能例程,实现AD采样、pwm产生等功能(CCS all functional routines, realize AD sampling, PWM generation and other functions)

说明：  STM32通过模拟IIC读PCF8574(STM32 reading pcf8574 through analog IIC)

采用四端法测试欧姆电阻，并把结果显示在lcd上，采用c8051(Four-terminal method using ohm resistors, and the results displayed in the lcd, using C8051)

这是基于飞思卡尔十六位单片机的RS485通信的例程(freescale RS485 routine)
