[RT1170] [LPADC] ADC sample project problem

[ZHOU_XIAO]

Hello ,All

I am testing the LPADC sample project for customer.

As Readme shows that the ADC can convert each value for J9-10 and J9-16,.

As far as I have measured ,

But  J9-16 value is always same as that of J9-10(Input voltage to J9-16 is different from J9-10) and can not detect the voltage well.

The J9-10 can detect the value well.

Could you confirm this sample code? Our evaluation condition is as below. [Board] SDK_2.x_MIMXRT1170-EVK [SDK] SDK Version 2.11.1 [Sample Code] driver_examples\adc_etc\adc_etc_hardware_trigger_conv\cm7\lpadc_etc_hardware_trigger_conv.c

Hi @ZHOU_XIAO ,

   We are NXP colleague!

   In fact, if you have any issues, you can create the internal question post here in stead of the public community:

https://community.nxp.com/t5/RT-4-Digit-10xx-11xx-12xx/gh-p/52590

  Then our AE can help us directly.

   To your question, do you connect the J9-10 and J9-16 to the same fixed voltage, which voltage point in the MIMXRT1170-EVK board? About the connection, you also need to make sure the wire connection is good!

  Then, I will assign time to test it.

  If we find any issues, we also can report to our SDK team directly.

Best Regards,

Kerry

Hello,@jerryzhou

 

SDK team member Albort XUE has already sent me the modified C source file to me and

after replacing the C file source, it turns to work well now.

Sorry to post this problem in public community , I will post in internal community next time.

Best regards

Hi @ZHOU_XIAO ,

   Thanks for the updated information, so it is confirmed the SDK bug, and internal side already report it, right?

   As our new SDK will be published in the near future, so, it's better to report to the SDK team to fix it, thanks.

Best Regards,
