ADS1232 verification board

Overview

This is a 24-bit differential input ADC solution verification board. The chip uses TI (Texas Instruments) ADS1232. This is a 24-bit differential input analog-to-digital converter. Features:

Low noise, 17nV when working at 10SPS, 44nV when working at 80SPS
Built-in low-drift oscillator, 3% error, optional external oscillator
Optional gain is 1, 2, 64, 128 times
External reference voltage up to 5V
Built-in 2 differential inputs with temperature sensor
Simple digital serial interface
The supply voltage is 2.7-5.3V
Temperature range -40°C to 105°C

Typical applications: weight scale, strain measurement, pressure sensor Typical application example circuit: For the weight scale Weight scale application.png test, I used the STM32F103 development board, and the wiring method is as follows:

SCLK=====PA6
PDWN=====PA5
DOUT=====PA4

I want to make an automatic tracking smart car with black lead wire. Should I use a three-way infrared pair tube or RPR220?
I want to make an automatic tracking smart car with black lead wires. Is it better to use a three-way infrared tube or a photoelectric sensor chip RPR220? I initially plan to use C51 to write it. Whic

Can anyone give me a program to measure the voltage of MSP430G2553 through AD external and send it through the serial port?
As the title says. Thank you.
