一种高精度恒流源电路的设计与实现

说明：  STM32F103系列模拟USB串口实验，使用KEIL平台(STM32F103 series simulation USB serial port experiment, using keil platform)

说明：  stm32示波器 驱动代码，包括算法，非常有帮助。是在keil5上开发，而且是用的是efm32的芯片。(STM32 oscilloscope driver code, including algorithms, very helpful. It is developed on keil 5, and it uses the chip of efm32.)

ad7991测试程序，需要自己填写控制字(ad7991 testing procedures need to fill their own control word)

取键盘指示灯状态源码，例程程序调用API函数实现取键盘指示灯状态。(Take the keyboard LED status source , routine program calls API functions take keyboard LED status .)

说明：  这段程序是用在一款七彩灯红外遥控解码程序里,单片机使用PIC12F629,软件模拟三路PWM输出驱动红绿蓝LED分八组共24个LED,实现单LED渐明渐暗,两LED一明一暗,七彩等九种花样.有断电记忆功能(This procedure is used in a colorful light infrared remote control decoding procedure, the single-chip using the PIC12F629, the software simulation of three-way PWM RGB LED output driver in eight groups of 24 LED, single LED gradually dimming out, two LED Kazuaki a dark, colorful patterns, such as nine. have power memory function)

linux系统与单片机通过ymodem协议传送文件(linux system send a file to mcu form serial.)

附件为LabVIEW的vi程序和说明文档。描述：利用LabVIEW2012设计PID控制器，利用PID工具包，在LabVIEW仿真工具包中的控件与仿真循环中搭建PID控制器,并实现了闭环控制系统波形图的显示。(Attachments are the LabVIEW vi program and the documentation for PID controller design. The program includes the PID controller constructing and the closed-loop system output display.)

OLED显示屏HGS128321的程序，基于51单片机，主控IC问SSD1305(OLED display :HGS128321 , based on 51 single-chip microcomputer, the controller is SSD1305)
