 Hello Forum,

   

I want to measure few milliohms to ohms of resistance. What can be the best option? Is it possible to measure with PSoC3/5. How do I implement one.

Here the link to the EDN article: www.edn.com/design/systems-design/4402904/Complete--low-cost--software-programmable-ohmmeter-measure...

   

It would be interesting which part of this can be done in a PSoC. I could image to use the first IA, and after that directly connect a 24bit ADC.

 I will try to implement one with PSoC and will let you know if this is successful.

Thanks for posting the project. I always wanted to get a hold of thouse files to compare with what I was doing. I asked Dave but never got a reply. How did you manage to get it?
