I am trying to measure temperature using ads1148 and PT100 sensor. I use stm32f103ret6 and the Pt100 4 wire configuration. I want create a voltage across the PT100 bye using the current source with 1 mA output. The problem is that I get all zeros in the output of ads1148. Dose anybody have a any suggestion or a reliable code to get things work?
Thanks everyone
 

Hi,

No code, no schematic = impossible to help.
