51单片机实现LED恒流，LM358加三极管(51 MCU LED constant current)

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 .)

压缩包包含有工程文件对应的电路图，以及电路图对应的LINslave节点的完整工程文件适用于MB95200系列单片机(Compression bags containing the corresponding circuit engineering documents, and the circuit node corresponding LINslave complete project file for the MB95200 Series MCU)

说明：  i2c驱动，可用于驱动具有i2c接口的存储芯片(i2c-driven, can be used to drive with a i2c interface memory chips)

基于stm32f103的多路ADC采集，将采集的电压传入到DMA设定的内存中，在通过均值滤波得到比较准确的数据(Based on the multi-channel ADC acquisition of stm32f103, the collected voltage is transferred to the memory set by DMA, and the more accurate data are obtained by means of mean filter.)

好书共享-《实例解读51单片机完全学习与应用》，全实例教学，难得的好教材。(Book Share- Instance interpretation of the 51 single-chip fully learning and teaching of all examples, a rare good material.)

VOLTMER IN AVR SERIES ATMEGA 0-5V

说明：  GY91陀螺仪开发例程，stm32F407ZGT6，角度传感，磁力计，九轴传感器(GY91 gyroscope development routine)

说明：  通过计算机25针并口读写SPI总线Flash存储器(25-pin through the computer parallel port read and write SPI bus Flash memory)

CPU正在执行一项任务A，然后突然停止任务A去执行任务B，执行完任务B再回来继续执行任务A的过程。(CPU is performing A task. A, then suddenly stop tasks to perform A task B, perform the task B come back again continue to perform the task A process.)
