Hi All
I am new to Arduino and Electronics so please bare with me and try not to laugh at my basic errors and attempts now that out of the way.
is there a library available for ADS1244 ?
is there wiring diagram for ADS1244 ?
is there front end ready board available for ADS1244?
and lastly any help and advice regarding making front end PCB i have started and already think if fer things that can be added like opamp . variable voltage devider and one more voltage regulator for vrefn with variable resister to be able to use full range of ADC
Please see attached.
IC1=ADS1244 (24bit ADC)
IC2=LM317T (voltage regulator for AVDD and may be able add divider for DVDD)
i am sure there is better options i just added these as i have few laying round form what i ordered to wire my dashcam in car.
IC3=LM317 (voltage regulator for VREFP may be able to add var resistor for changing the ADC range)
missing
one more voltage divider for VREFN
variable divider for scaling down the signals outside max range
opamp for scaling up the signals too low (might not need as i have not studied datasheet in detail and again I am just armature and dont have good knowledge of electronics

Is there an online search engine available that scans through billions of web pages to get you the answers you need?
What is a "front end ready board"?

How are you ever going to get a good knowledge of electronics if you don't study the datasheets of parts you use? You might not understand everything the first time you read it, but that doesn't matter, that's part of the learning process.
What kind of signals do you want to measure?
My Idea of Front end board is to have a ADC board that can be configured to use full range

you are absolutely right I will try my best to do so I did read the datasheet but not studied it (was trying to hide my lack of knowledge of electronics and hoping for some help)
I did Came across the thread mentioned above and the code i was hoping for ready to use library (again to make my life easy again apology for not mentioning )
initially I just want to measure 0 to 5V (pressure sensor -100Kpa to 900Kpa)(can be achieved with simpler circuit )
but idea is to make a board to be able to take different types of sensors (some are mV output)
another reason for the effort was to make something that might be useful for others and not just me.
Hope I have not offended or annoyed you guys with silly questions.
