摘　　要：本文设计的基于MSP430和HX711的自制电子称,是以MSP430F149单片机为控制核心,采用电阻应变片作为压力传感器,24位电子秤专用AD转换芯片HX711对传感器采集到的模拟量进行AD转换,转换后的数据送到单片机进行计算和滤波处理,矩阵键盘进行功能控制,用12864点阵液晶输出显示。The self made electronic weighing instrument based on MSP430 and HX711 is designed in this paper. It takes the MSP430 F149 as the control core, uses the resistance strain gauge as the pressure sensor. The 24 bits ADC HX711 makes AD conversion to the analog amount collected by the sensor. The converted data is sent to the MCU for calculation and filtering. Matrix keyboard controls the function and LCD12864 shows the data.
