hello all. I need your help on a project that includes the reading of a pressure transducer. To perform the analog-digital conversion acquired the PmodAD5 and I have no idea how to acquire the information to my chipKIT Max32. I have not much experience with microcontrollers for this reason I need help.

Anyone knows of any example using this converter for better idea.

In advance thank you for your help.

According to the manual (you have read it, haven't you?)

The PmodAD5 has a 4-wire SPI communication interface.

So therefore you can use the DSPI library to communicate with it using any of the SPI ports of the MAX32.

The chip is the AD7193, and the data sheet for that is here: [url][/url]

That details the SPI interface for you, including configuring the various registers, etc. Page 21 is where that information starts.

It seems to be a bit cryptic, but I think you send a communication register byte to select the register you want, then send or read the data for that register.
