Modbus_4

说明：  通过STM32的spi接口读取陀螺数据和加计数据，并对寄存器数据进行温补(Through the SPI interface of STM32, the data of gyro and add-on are read, and the data of register are compensated)

stc12c5a60s2读取mpu6050六轴原始数据(stc12c5a60s2 read mpu6050 six-axis raw data)

电子称重的实现首先是通过压力传感器采集到被测物体的重量并将其转换成电压信号。输出电压信号通常很小，需要通过前级信号处理电路进行准确的线性放大。放大后的模拟电压信号经AD转换进入主控单片机中，再将结果显示在人机界面。(The realization of electronic weighing is firstly to collect the weight of the measured object through a pressure sensor and convert it into a voltage signal. The output voltage signal is usually very small, which requires accurate linear amplification through the front signal processing circuit. The amplified analog voltage signal is converted into the main MCU by AD, and the results are displayed in the man-machine interface.)
