By encapsulating the details of the code to communicate with the device, the program becomes extremely simple. Program:
Now in this particular case, pin 24 is reserved because it's the chip select line for the SPI bus. If I read the LINX source code here correctly. I think it should already be using pin 24 as a chip select. So if you specify some unused digital output line to pass in to the SPI Read VI, I think it all might work.

By modifying the sample code provided, I've printed out the converted data and ploted them, which is the figure shown below (y-axis = voltage, x-axis = number of data) figure 1: sine wave plot; Here are the questions: Is this normal phenomenon for this ADC board? If so, am I correct to assume that this ADC can only receive analog inputs above zero?

The ADC on the board is an ADS1256, and I am having trouble finding code libraries to use with it. Previously I was working with an MCP3008 (I am testing this board out because of the increase in precision for voltage measurements) and GPIOZero was a great library for that chip.

All documentation provided by WaveShare was referring to Raspberry Pi running Linux and the source code examples was written in C, so I had to write my own library. The first challenge was to try to understand how the Linux code actually communicated with the board, and it turned out to be quite a detective work.
The code itself doesn't necessarily need to be TIVA 129 specific (that'd be great if it was). I'm just looking for sample code that puts the SPI bytes together that properly configures the ADS1256 to help speed up our development. Thanks!

Is the data clock idle when high or low? Are samples on the rising or falling edge of clock pulses? These modes are controlled by the third parameter in SPISettings. The SPI standard is loose and each device implements it a little differently. This means you have to pay special attention to the device's datasheet when writing your code.
