My use CY8 CKIT-001 kit Measuring temperature(The sensor is pt100).For external hardware connection:RTD_4_0 and RTD_4_1 connection PT100.then Connect the RTD_4_1 to RTD_3_0 .RTD_4_4 and RTD_4_5 connection Reference(100Ω) resistor.in the end Connect the RTD_3_4 to RTD_4_4. I don't know my way such hardware connection is correct, bother everybody to help me have a look, thank you!!!(The following is my project)
Solved! Go to Solution.

After studying Your program it appears that your ADC is only read once and your program never reads the Cal channel or increments the current mux. I am sending you another example for you to study.

RTD_3_0 is nowhere mentioned.

I'm sorry I write wrong。I connection:RTD_4_0 and RTD_4_1 connection PT100.then Connect the RTD_3_1 to RTD_4_0 .RTD_4_4 and RTD_4_5 connection Reference(100Ω) resistor.in the end Connect the RTD_3_4 to RTD_4_4.But didn't read the correct temperature.The LCD has been show -0.01,Adjust the resistance box resistance and no change。

Thank you for your reply.My project files inside the AD sampling reference benchmark will once, but the AD value more than gathering at a time.But when debugging acquisition resistance and temperature.I saw you gave me the thermistor project, I PTC temperature sensor is a bit different, but do you have any RTD course?Thank you very much.
