摘要
介绍了基于HT48R50A-1单片机的电子计价秤的软硬件设计方法.提出了由双积分模拟电路替代价格昂贵的AD转换芯片,在保证测量精度的同时达到降低成本的要求.同时设计了电压检测和复位电路,使系统更加精确、高效、可靠.
The software and hardware design method of electronic balance based on HT48R50A-1 MCU is introduced. The method replaces expensive AD exchange IC by double integral analog circuit, not only assuring measure accuracy, but also meeting the low cost demand. Meanwhile, the voltage checking and reseting circuit function optimize the accuracy system, efficiency and reliability of the system.
