C51下液晶显示屏驱动例程。1602液晶和12864液晶。(C51 under the LCD driver routines. 1602 and 12864)

说明：  本文从硬件出发，系统地讲解了文件系统实现的原理，内容详细全面而有条理(Starting from the hardware, this paper systematically explains the principle of file system implementation. The content is detailed, comprehensive and orderly.)

STM32 外部中断程序，用于学习用中断来控制按键(STM32 External Interrupt program)

说明：  利用DHT11采集温湿度，利用中断，每2秒采集一次，并利用串口传输至上位机系统(use DHT11 to get temperature and humidity)

8、可变频率方波发生器 用单片机的定时器设计一个频率可变的方波发生器，输出频率范围1Hz~500Hz，频率输出精度为0.5Hz。要求可以实时显示当前输出的频率，可以用键盘来设定方波发生器的输出频率，具有直接设定或逐渐调节的功能，调节分辨率和显示分辨率均为0.5 Hz，其它电路自由发挥。(8, variable frequency square wave generator with single-chip microcomputer timer design a variable frequency square wave generator, the output 1 Hz ~ 500 Hz frequency range, frequency output precision is 0.5 Hz. Requirements can real-time display current output frequency, can use the keyboard to set the output frequency of square wave generator, has the function of directly set or adjust gradually adjust the resolution and display resolution of 0.5 Hz, free play other circuits.)

用于TI 3S9B96开发板 实现功率转换的功能(Development board for the TI 3S9B96 achieve power conversion function)

说明：  些程序为STM32F103VET6驱动CMOS摄像头OV7670的程序。采用AL422B作为FIFO帧缓冲，显示采用3.5寸TFT ILI9481，单片机FSMC方式驱动TFT，非常好用。(These procedures STM32F103VET6 drive OV7670 CMOS camera program. As the FIFO frame buffer with AL422B display with 3.5-inch TFT ILI9481, are driven SCM FSMC TFT, very easy to use.)

自己编的听觉掩蔽的程序，在程序中有说明。(own addendum to the auditory masking procedures, the process is described.)

For Practice in Electrical Digital Laboratory

说明：  PS2无线手柄资料，带例程 ps2 手柄兼容索尼的 PlayStation2 游戏机的遥控手柄。索尼的 psx 系列游戏主机在全球很是畅销。不知什么时候便有人打起 ps2 手柄的主意，破解了通讯协议，使得手柄可以接在其他器件上遥控使用，比如遥控我们熟悉的机器人。突出的特点是这款手柄性价比极高，按键丰富，方便扩展到其它应用中。(PS2 wireless handle data with routine The PS2 handle is compatible with the remote control handle of Sony's PlayStation 2. Sony's psx series game console is very popular all over the world. I don't know when someone came up with the idea of PS2 handle, cracked the communication protocol, so that the handle can be connected to other devices for remote control, such as remote control of familiar robots. The outstanding feature is that this handle has high cost performance and rich buttons, which is easy to extend to other applications.)
