28335实现电量的采集、处理、12864液晶显示。试验箱上验证通过。(28335 the realization of power acquisition, processing, 12864 liquid crystal display. Verified by test box.)

电子爱好者们经常希望测试自己的音频设备如声卡、碟机、功放、音箱等的性能指标，却苦于没有价格高昂的专业测试设备而无从下手，设计制作时也无法进行必要的测试指导。有些CD碟提供了测试信号，如著名的“雨果发烧碟（一）”、“My Disk”等，《无线电》也曾推出音频测试CD。但CD信号的精度有限，而且没有操作系统的配合，测量、记录和分析都很不方便。(Electronic fans often want to test their audio devices such as sound cards, CD, amplifier, speakers and other performance indicators, but have no specialized test equipment without the high price the start, can not carry out the necessary tests to guide the design of production. Some CD discs provide a test signal, such as the famous Hugo Audiophile CD (a) , My Disk and so on, Radio has launched an audio test CD. CD signal but the accuracy is limited, and there is no tie, measurement, recording and analysis of the operating system is very inconvenient.)

51单片机控制ADC和DAC转换的程序，仅供参考(51 MCU control ADC and DAC conversion process, for reference only)

说明：  sd卡初始，由于SD卡使用SPI模式，并且是块读取(512Byte),所以需要单片机提供大于512的可用RAM，以供缓冲使用 这里可以选择STC89c52RD+、STC89C58RD+、STC89C516RD+，后缀RD+表明扩展RAM是1024字节，RC表明扩展RAM256字节(sd card original, because the SD card using SPI mode, and is a block read (512Byte), so they need the microcontroller to provide more than 512 of the available RAM, for buffer used here can choose STC89c52RD+, STC89C58RD+, STC89C516RD+, the suffix RD+ that extended RAM is 1024 bytes, RC that extended RAM256 byte)
