Due to the fact that the power supply voltage of ADS1256 is 5V, and the measured voltage should be 2V lower than the power supply voltage, the module is only suitable for measuring analog voltages within 3V 
The module provides reference programs for STC15W&&STM32 microcontroller 8-channel serial port display and STC89C52 microcontroller 4-channel 1602-LCD display. The simple testing method for STC89C52 microcontroller+1602LCD LCD is as follows: 
5V and GND are connected to a DC 5V power supply. SCLK, DIN, DOUT, DRDY, and CS are respectively connected to P1.2, P1.3, P1.4, P1.5, and P1.6 of the microcontroller. AIN0, AIN1, AIN2, and AIN3 are respectively connected to 2.5V, 2.5V, 2.5V, and 2.5V (the measured voltage should be grounded with ADS1256)
Four sets of voltage values will be displayed on the 1602 LCD, with the first, second, and fourth sets being the single ended input voltage values of AIN0, AIN1, and AIN3, and the third set being the difference between AIN2-AIN3. The four voltage values are approximately 2.5V, 2.5V, 0V, and 2.5V, respectively

==Precautions==
Due to the fact that the power supply voltage of ADS1256 is 5V, and the measured voltage should be 2V lower than the power supply voltage, the module is only suitable for measuring analog voltages within 3V.
