最近非常流行的STC增强型单片机PDF应用资料(Recently very popular STC-enhanced single-chip application information PDF)

基于430单片机实现的AD9852信号发生器。可以实现键盘输入频率选择，也可实现频率范围内扫频，功能菜单由12864显示(the AD9852 signal productor based on 430 MCU ,the frequency of signal can be controled by 4*4 keyboard .)

说明：  msp430单片机，M5310模组实现NB-Iot通信，对学习NB有帮助(MSp430 MCU and M5310 module realize NB-Iot communication, which is helpful for learning NB)

单片机型号为ATmega8，内有1206LCD控制器、采用恒压跟踪的MPPT算法、横流输出控制(The model of single chip microcomputer is ATmega8, with 1206LCD controller, MPPT algorithm with constant voltage tracking, cross flow output control)

通过51看门狗定时器的使用，了解看门狗定时器的功能(Through the use of the watchdog timer 51, ​ ​ the Watchdog Timer function )

STM32转换ADC值并通过LCD1602进行显示(STM32 converts ADC values and displays them through LCD1602)

本程序会将WIFI模块发送的数据转发到USART1串口，同时将USART1串口接收到的数据转发给WIFI模块。这样客户就可以通过HL-340的USB转RS232串口线来测试WIFI模块的AT指令了。(The data in this program will be forwarded to the WIFI module sending USART1 serial port, while forwards USART1 receive serial data to WIFI module. So customers can be transferred via RS232 serial cable HL-340' s USB WIFI AT command to test the module.)

基于STC89C52单片机实现中断LED数码管显示及处理的程序，适合初学值使用(Based STC89C52 MCU interrupt LED digital display and processing procedures, suitable for beginners to use the value)
