adc16_config_t has no member named 'hardwareAverageMode'

I'm using MCUXpresso v11.5.0, and SDK_2.x_FRDM-K66F 2.11.0. My board is a FRDM-K66F.

For ADC0 and ADC1, both of which have "hardware averaging disabled" in the Peripherals configuration screen, I get:

.hardwareAverageMode = kADC16_HardwareAverageDisabled,

in the generated "peripherals.c" file. However, that gives me a compiler error:

../board/peripherals.c:400:4: error: 'adc16_config_t' {aka 'const struct _adc16_config'} has no member named 'hardwareAverageMode'

  400 |   .hardwareAverageMode = kADC16_HardwareAverageDisabled,

      |    ^~~~~~~~~~~~~~~~~~~

I've commented it out so I can compile, but I'm perplexed that I'm getting this error at all in a MCUXpresso-generated file. It also risks breaking the XML needed by the Peripherals page.

Any suggestion for why this is happening, and how to fix it?

Thanks, Aaron

Hi @aaronminner

I would like to apologize for the delay, we are experiencing a high volume of questions these days. I really appreciate your patience.

Regarding your issue, I see that you probably are missing to add the pointer to the structure with the operator -> in order to avoid the error as shown as below:

Hope this helps, please let me know if you have more questions.

Best Regards.
Pablo Avalos.

Thanks for getting back to me, Pablo. Actually, it turns out it's more related to this:

/*! * @brief ADC16 converter configuration. */ typedef struct _adc16_config { adc16_reference_voltage_source_t referenceVoltageSource; /*!< Select the reference voltage source. */ adc16_clock_source_t clockSource; /*!< Select the input clock source to converter. */ bool enableAsynchronousClock; /*!< Enable the asynchronous clock output. */ adc16_clock_divider_t clockDivider; /*!< Select the divider of input clock source. */ adc16_resolution_t resolution; /*!< Select the sample resolution mode. */ adc16_long_sample_mode_t longSampleMode; /*!< Select the long sample mode. */ bool enableHighSpeed; /*!< Enable the high-speed mode. */ bool enableLowPower; /*!< Enable low power. */ bool enableContinuousConversion; /*!< Enable continuous conversion mode. */ #if defined(FSL_FEATURE_ADC16_HAS_HW_AVERAGE) && FSL_FEATURE_ADC16_HAS_HW_AVERAGE adc16_hardware_average_mode_t hardwareAverageMode; /*!< Set hardware average mode. */ #endif /* FSL_FEATURE_ADC16_HAS_HW_AVERAGE */ } adc16_config_t;

This is in fsl_adc16.h. I don't recall doing anything in particular to make FSL_FEATURE_ADC16_HAS_HW_AVERAGE defined, but my project is now compiling without any work-arounds for this particular aspect. It might have been when I tried to clone a 2.8 SDK project - which worked as expected - and then updated the SDK to 2.11. At some point, I stopped trying to do that - it was too much hassle and never worked correctly - and just created a 2.11 project, instead. At any rate, yeah, I'll close this issue, now.
