ADS1256 - Reading a single conversion result using RDATA

UPDATE:
Since this video, I created my own custom library for the ADS1256. Please visit my website for the library files and for a very detailed documentation:
https://curiousscientist.tech/ads1256-custom-library

In this video I show you how to read a single conversion result from the ADS1256 via SPI communication using an Arduino. I explain a few things in more details such as shifting out the three bytes (MSB, Mid-byte, and LSB) and constructing the 24-bit conversion result. I also talk about the representation of the negative sign and how the conversion result is converted into voltage.

In the beginning of the explanation I made a mistake. The writeRegister(0x01, B00101000); is selecting the [AIN2] as the positive input pin. In order to select the [AIN0 + AINCOM] combination, you have to use writeRegister(0x01, B00001000);
