hi , i would like to know how to interface AD590 temp sensor with arm, i am not able to calibrate it properly
This is reply No 2 in this thread:
How to interface to an arm? You pick up the AD590, then press it hard enough against the skin. Preferably apply some grease to reduce the temperature coefficient.
Oh. You mean interfacing with an ARM processor? Wouldn't that depend very, very, very much on which specific ARM processor? You do think it's the ARM core you interface with, and not the processor-specific peripherial functionality?
You have located the datasheet/user manual for yuor processor? We most definitely have not - we don't even know which processor so are totally unable to.
It states that you need to provide more information before any answer is possible!
Have you studied the Datasheet for whatever ARM processor it is that you're using?
tell for lpc2138
So what do you do if you have a current generator and want to measure the generated current?
Knowing that it's the LPC2138 that is used, you would then also know what peripherial hardware that processor contains. See any suitable hardware for the task? What is the full range currents you may get from the sensor? What is the full range xx that the processor can measure? What would then a suitable method be for maintaining as good a resolution as possible?
Have you read the Datasheet for the LPC2138?
As it's an NXP part, you will also have to study the User Manual
