Hi,
I am testing the component Die temperature with the boad CY8CKIT-041-41XX, bur the temperature value is wrong: -30°C at 25°C ambient.
I am using your example code called CE195275 – Sequencing SAR ADC and Die
Temperature Sensor with PSoC 4.
Why is there this difference ?
Best regards

Hi Lube,
The example is generated for PSoC4 devices with internal reference of 1.024V. The one you are using is a PSoC4 with 1.2V internal reference. Modifications must be done in the code to get an accurate result in this case.

Hi LuBe,
Could you please share the project you are using? Kindly share PSoC creator and the die temperature versions you are using too.
Best Regards,

Hi Vasanth,
first test is ok with DIETEMP_VREF_MV_VALUE (1200) and ADC VRef internal setted, but if I change VRef internal in to VDDA (1V9) the value returned is complety wrong.
Best regards
