基于FM芯片RDA5807的51单片机的FM收音机，通过IIC协议控制芯片实现调台、调音量功能。(Based on FM 51 MCU chip RDA5807 FM radio, through the IIC protocol control chip to realize the radio, the tuning function.)

说明：  基于单片机的信号发生器的设计，有具体的硬件图和源码(Signal generator based on single chip design, there are specific hardware diagram and source code)

ist3931 spi driver for ist3931 ic(ist3931 spi driver for ist3931)

IDC3516-4-20mA电流环隔离接口芯片的应用(IDC3516-4-20mA current loop isolation Application Interface Chip)

mipi传输，用于新型图像传感器的传输问题(MIPI transmission, new image sensors for the transmission problem)

是我买的c8051f020送的光盘！上面东西很齐全，用于c8051f020的学习！很多源程序（C语言），便于学习和参加全国电子设计大赛的培训(I bought the CD c8051f020 sent! The above things are complete, for c8051f020 learning! Many source code (C language), easy to learn and participate in the training of the National Electronic Design Contest)

说明：  由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)

基于stm32的速度闭环，直流无刷电机驱动程序。(Based stm32 speed closed loop brushless DC motor driver.)

说明：  轮流点亮P1口所接LED并循环显示，间隔0.5s(Turn on the LED connected to P1 port in turn and display circularly, with an interval of 0.5s)

可以在液晶显示两个数计算结果，只能进行两个数的计算(The results can be calculated by two numbers in the liquid crystal display)
