Hi,

   

My first post - so go easy please.  I'm new to PSOC 4 BLE and am looking for an RTD sensing example specifically with the 12bit SAR ADC and IDAC source (op-amp pre-amplifier?)  I'm not expecting great accuracy but I'm hoping for +/- 0.5-1C.  

   

I've started with trying to modify the provided examples for PSOC 3 and 5 but am running into some problems because of the different ADC.

   

Thanks in advance.

   

J.

The PSoC5LP samples use the DelSig ADC, which the PSoC4 misses.

You can look at AN66477 (though its for a thermistor) which shows using the SAR ADC on the PSoC4 for temperature measurement.

Hi Jonathan

   

can you elaborate the difficulties you have a little bit?
I am wondering how different he SAR ADCs between PSoC4 series and PSOC5 series really are.

   

All the Best
Frank
