Dear Sirs,
a few months ago you valuable Bob Benjamin gave me some hints for designing a 4x RTD (PT1000) interface using the ADS1248. Now the hardware is ready and our s/w engineers need some hel to make system firmware development faster. In order to avoid as possible - like we say - to "discover hot water".
The final schgematic of the interface is in the file (attached).
I'm not asking for the code, but just for the correct sequence of actions to do: i.e.: registers to be programmed and suggested values, and suggestions to avoid critical issues, to make ADS1248 management (connected as from the image) almost instantly working in the best way.
The temperature reading process hasn't to be fast. 20 readings/second could be ok.
Any suggestion and contribution is welcome.
My best regards
Paolo Bozzola
