Interfacing with 24-BIT ADC ADS1232/1234 for weight measurement

Hi, I'm having a hard time interfacing with ADS1234 (which is a 24-bit ADC with SPI), simply because I have no experience. I am using the configuration suggested in figure 42 of the Datasheet. http://www.ti.com/lit/ds/symlink/ads1234.pdf

I'm using an Arduino Uno and the goal is to simply read a voltage signal (5mV max) from a load cell, and convert to mass. The ADC has 4-channels but I'm only using one.

Can anyone share example code?

Thank you very much
