说明：  stm32f103DAC输出两路正弦波600hz 2100hz(STm32f103DAC Outputs Two Sinusoidal Waves 600 Hz 2100 Hz)

首先说明ADS1158命令读写模式，然后解析命令含义及配置顺序等。(First, the ADS1158 command read and write mode, and then parse the command meaning and configuration order and so on.)

说明：  本程序可实现基于51单片机的电子秤数据采集、滤波、显示功能。 称重范围：0-1000g 分辨率： 0.1g 测试精度：0.2g 设计架构：采用弹性悬臂梁贴应变片的传感器结构，应变片采用全桥连接。电桥输出经AD芯片发送给微处理器，微处理器经过数据处理后显示。(This program can realize the functions of data acquisition, filtering and display of electronic scale based on 51 single chip computer. Weighing range: 0-1000g Resolution: 0.1g Testing accuracy: 0.2g Design framework: The sensor structure of elastic cantilever beam with strain gauge is adopted, and the strain gauge is connected by full bridge. The output of the bridge is sent to the microprocessor by AD chip, and the microprocessor is displayed after data processing.)
