LPC54618 ADC Self calibration using deprecated function

[jared77]

I recently moved from MCUXpresso 11.3 to 11.5.1. I noticed that my ADC isn't reading properly anymore. I have been using LPC54618 sdk 2.9.0 if that matters

I noticed that the auto-generated code in my project before upgrading used ADC_DoOffsetCalibration, and after re-generating my peripherals.c file, ADC_DoSelfCalibration is used. I then noticed that ADC_DoSelfCalibration is deprecated and when I switch back to the old function I'm able to accurately read the microcontroller's internal temperature sensor again.

I won't go into specifics of the combinations but I have tried regenerating my peripherals.c file with various combinations of MCUXpresso including 11.4, 11.5.1, and 11.6. I've also tried SDKs 2.11.1 and 2.12.0 in various IDE versions. All combinations of the SDKs and IDEs so far have resulted in the deprecated function.

Is there anything I can do about this or do I just have to manually edit the generated code each time I generate?

Thanks!

Hello,

You can enable this function as below:

Alice,

I'm already using that to generate the code. The issue is that the generated code is using a deprecated function that doesn't work. Old versions of MCUXpresso generate code with the correct function while new versions use the deprecated function.

Hello,

 Does the "old version" is SDK v2.9? 

[jared77]

Yes, the old version was SDK v2.9 and IDE version 11.3.0. I think that the config tools are to blame as using SDK v2.9 on IDE v11.5.1 still generates with the deprecated function.

Hello,

I compare the function ADC_DoSelfCalibration() between SDK v2.9 and v2.12, there is no difference.

Could you please share the code in  ADC_DoSelfCalibration() from IDE v13?

Alice,

ADC_DoSelfCalibration() is the Deprecated function and has been from SDK 2.9-2.12 and maybe even before then, see my screenshot. I said in the last post the SDK isn't the issue, it's that the config tools are using ADC_DoSelfCalibration() which is deprecated rather than ADC_DoOffsetCalibration(). IDE v13 config tools generated code using ADC_DoOffsetCalibration() which was correct.

Hi jared77,

sorry for inconvenience, attached is the patch to generate correct function.

Patch is updated to production version.

Have a nice day

jch,

I looked at the patch you sent, I used a diff tool and it's already present in both the mcu_data_v11 and mcu_data_v12 folders on my machine. I applied the update and the code generation in MCUXpresso v11.5.1 is still trying to use the deprecated function. Could there be another newer patch already applied that I might need to remove or something?

Hi jared77,

sorry, now the patch above is updated to the production version and should work.

Have a nice day

Thanks for the updated patch!

I installed it in the mcu_data_v11 folder and the code generates properly now.
