MSP430F149控制SD卡读写操作，支持FAT16文件系统(The MSP430F149 Control SD card read and write operations to support the FAT16 file system)

基于新唐M453的串口1数据收发和对led灯的控制，可以通过串口助手来监听看到数据变化。(Based on the new Tang serial 1 data transceiver and control of the LED light, you can monitor through the serial assistant to see data changes.)

说明：  stm32直流电机电机编码器 定时器编码器模式(timer encoder mode........)

240128演示程序 采用t6963演示汉字(unsigned int i,j CmdWrite(0x5c) DataWrite(0x00) DataWrite(0x00) CmdWrite(0x46) DataWrite(0x00) DataWrite(0x04) //csr=0x0400 字摸地址80H CmdWrite(0x4c) CmdWrite(0x42) )

STM32控制24位ADC实现模数转换功能，并利用OLED显示。(STM32 controls the 24 bit ADC to realize the analog-to-digital conversion function and displays it by OLED.)

搞了十几天，终于实现了无线模块NRF24L01可以发送和接收到一串字符了，本程序含发送程序，和接收程序，单片机用AT89S52,把显示的字符串显示在1602上(Out of the 10 days, finally achieving a wireless module NRF24L01 can send and receive a string of characters, and this procedure with sending program, and receive program, microcontroller use AT89S52, the display on the string displayed in the 1602)

说明：  I2C_SHT21 温湿度传感器测量 I2C 读取SHT21 温湿度传感器 SHT21驱动库有两种操作模式，适合不同操作 自动转换测量模式： 1：启动任意一个测量指令,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值, autoMeasure(float * th); 该函数读取测量得出的数据，并根据数据的类型进行转化，再自动启动下一个类型的测量 指定转换测量模式： 1：先启动一次测量,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值,例如读取温度执行readT();(2C_ SHT21 temperature and humidity sensor measurement I2C read SHT21 temperature and humidity sensor SHT21 driver library has two operation modes, which are suitable for different operations Automatic conversion of measurement mode: 1: Start any measurement command, for example, measure the temperature and execute measure(); 2: Delay 200ms 3: Read the measured value and Automeasure (float * th); This function reads the measured data, converts it according to the data type, and then automatically starts the next type of measurement Specify the conversion measurement mode: 1: Start a measurement first, for example, measure the temperature; 2: Delay 200ms 3: Read the measured value, for example, read the temperature and execute readt();)

说明：  华大HC32L136额温枪方案，包含模拟传感器使用方式，源代码，硬件原理图等一整套方案。(Huada hc32l136 frontal temperature gun program, including a whole set of programs such as analog sensor use mode, source code, hardware schematic diagram, etc.)

ATmega16数码管实验基数显示，数码管选通输出在前避免了字码在前产生的乱码，Proteus图(ATmega16 base of digital tube experiments showed that the digital control of strobe output of the former to avoid the code generated by the previous garbled, Proteus map)
