hi , i would like to know how to interface AD590 temp sensor with arm, i am not able to calibrate it properly
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
