实现STM32单片机使用RDA5807M型号的芯片收音机，代码通过简单的移植，就可以使用。(Implement STM32 MCU chip radio RDA5807M model code by simply transplant, it can be used.)

ADC0832模数转换与LCD-LED显示，带Protues仿真，keil工程(ADC0832 analog to digital converter and the LCD-LED display, the band Protues simulation, c51 engineering)

通过comm口，读取外部压力或温度传感器的数据，并显示在界面上(Comm port by reading data the external pressure or temperature sensor, and displayed on the screen)

说明：  法国Humirel公司新一代HTU21D温度和湿度传感器驱动(The Humirel HTU21D is a new generation of temperature and humidity sensors)

SI4463的详细英文资料 SI4463 detailed information in English(SI4463 detailed information in English SI4463 detailed information in English)

安富莱这个二代示波器无敌牛，建议下下来学习学习！(Anfulei, the second generation oscilloscope, is invincible. It is suggested that we should learn from it.)

说明：  TCS3200颜色测试,读取RGB值,LCD1602显示R,G,B值(TCS3200 color test, read RGB value, LCD1602 shows R, G, B value.)

使用Jk触发器实现PLL鉴频器电路 还没仿真测试 只作为参考(jk flipflop for PLL frequency discriminator)

很强的射频卡reader源代码，支持ISO14443A、ISO14443B等卡片，支持Mifare卡，desfire 4卡，内嵌入3DES算法(A strong source of RF card reader, support ISO14443A, ISO14443B such as card, Mifare card support, desfire 4 cards, embedded 3DES algorithm)

stm32配置模板，了解 STM32 的标准库文件之后，我们就可以使用它来建立工程了，因为用库新建工程的步骤较多，我们一般是使用库建立一个空的工程，作为工程模板。以后直接复制一份工程模板，在它之上进行开发(Once you understand the standard library file for STM32, we can use it to build the project because of the new library build There are more steps, and we usually use the library to build an empty project as an engineering template. Direct a copy of the work later The process template is developed on top of it)
