Hello All,

I am very new to embedded environment, so please bear with me.
I am trying to read the values at all 4 channels of my ADC (ADS131M04EVM) using the EK-TM4C129EXL board. I am trying to do this over SPI.
I found some work from Texas Instruments here: https://github.com/TexasInstruments/precision-adc-examples/tree/main/devices/ads131m08

This work was integrated (or at least an effort was made View attachment 347550) with the Blinky example that comes with TivaWare.

Unfortunately, owing to my limited knowledge in the field, I am a bit stuck and clueless with what to do next.
I tried calling the adcStartup function, but I do not know if it even works, and how can I read the values of the ADC in realtime.

Can someone please help me? You can find my work on Github here: https://github.com/vivianjoshua/TM4C129WithADS131M04
I would immensely appreciate some guidance on this. Looking forward to your responses.

Sincerely,
Vivian
