I program the evaluation board using the Model-Based Design Toolbox from NXP in Simulink. NTC sensors are mounted on the MC33772C, and I need to read the temperatures measured by the evaluation board. However, the temperature conversions are incorrect. The analog voltages from the GPIOs of the MC33772C are correct, so I believe the issue lies with the conversion process. The conversion parameters, such as the NTC fixed resistance and NTC reference resistance, are correctly set. I tried configuring the GPIOs as ratiometric analog inputs, but the temperature conversions are still incorrect. I can't determine the cause of the problem.</SPAN></P> Fri, 10 May 2024 11:01:03 GMT URC 2024-05-10T11:01:03Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Error-conversion-of-voltage-drops-of-NTC-sensors-to-temperature/m-p/1863395#M9075 <P><SPAN>The MC33772C BMS slaves are connected to the S32K144EVB evaluation board via TPL lines.
