manage 32 bits

hello everybody,
I need an advice for an application, from a sensor with SPI output I have to read 4 registers in 32 bits, from which I then have to get measures and alarms of operation, which is the correct approach to manage 32 bits?
use array? circular buffer? or other?
Thanks for your help

Hi maxtisc,
Attached is a Flowcode 8 macro that reads 32bits (4 lots of 8 bit registers) of FT810.
I believe your device would be read similar to FT810 as that too has only 8 bit words.

Hi Martin
thank you very much for your answer, I uploaded the file, it seems very complicated to me, I ask you if you can explain the various steps to better understand how the macro works.
thank you

Hi maxtisc,
it was Ben Who created the macro, so I will see it I can help.
That was just an example.
What is the address you need to read from?

Hi Martin
thanks for your interest, attached the table for reading the registers, while I try to do something
thank's for your job

Hi maxtisc,
It would be more helpful If i know what the component is so I can access the full datasheet.
