iMXRT1170 LPADC Calibration.

[Naveed]

Hi,

I am using iMXRT1170 EVK board and tried the LPADC example code "evkmimxrt1170_lpadc_polling_cm7" in the SDK package. In the driver file fsl_lpadc.c I noticed that the calibration functions are greyout/disabled. In the example code also these functions are disabled as shared below.

1. What is the reason for not calling the calibration function in the example code?

2. How to enable the calibration function to run the ADC calibration?

3. What is the sequence of calling the calibration function? Do we need to call all the three function highlighted in the snippet or it will work for anyone function(if called directly)?

Thanks in advance.

Hi,

Thank you so much for your interest in our products and for using our community.

The calibration feature is not implemented in the RT1170. You should get close to the typical error specs in the datasheet without calibration.

Hope it helps you.

Have a nice day!
