ATT7022的采集，校准，纯软件实现。适合与多功能电表的开发！(ATT7022 acquisition, calibration, pure software implementation. Suitable for development with multi-meter!)

单片机初学者资料 51单片机C语言编程入门(详讲版)(Singlechip beginners )

说明：  一本较好的VB教程，主讲上位机编程，相信大家会喜欢的。(A better VB tutorials, keynote host computer programming, I believe you will like.)

说明：  郭天祥TX-1C版的Proteus仿真 三个版本(Guo Tianxiang TX-1C Version of Proeus Simulation Three Versions)

ATT7022电力计量芯片模拟SPI驱动(ATT7022 Electric power measurement chip SPI simulation drive )

This class can create DataEntryWriter instances based on class paths. The writers will wrap the output in the proper jars, wars, ears, and zips.

STM32红外发射源码，帮助新手学习，理解简单实用(STM32 infrared emission source, help novices learn to understand simple and practical)

说明：  数字滤波器，AD采样的值进行数字滤波，得到较理想的值(Digital filters, AD sampling the value of the digital filter, to be more ideal value)

说明：  STM32单片机6路ADC采样文件，并实现DMA传输，相当有参考价值(Bit Band of STM32 Single Chip Microcomputer)

这是一款数字电压表，ad转换之后显示出来，一个简单的例程(For robots, most of the information is obtained from visual sensors and tactile sensors (including slide tactile sensor). The visibility in the seawater of China is very low except Nanhai. Even in the water of high visibility, the water will be turbid and the visibility will become very low when the robot is working.)
