ADC INIT MK02

Hi there,

I can init most adc channel like the following

   ADC16_GetDefaultConfig(&adc16ConfigStruct);
   ADC16_Init(DEMO_ADC16_BASE, &adc16ConfigStruct);
   ADC16_EnableHardwareTrigger(DEMO_ADC16_BASE, false);                /* Make sure the software trigger is used. */
#if defined(FSL_FEATURE_ADC16_HAS_CALIBRATION) && FSL_FEATURE_ADC16_HAS_CALIBRATION
   if (kStatus_Success == ADC16_DoAutoCalibration(DEMO_ADC16_BASE))
   {
        PRINTF("ADC16_DoAutoCalibration() Done.\r\n");
   }
   else
   {
      PRINTF("ADC16_DoAutoCalibration() Failed.\r\n");
   }
#endif /* FSL_FEATURE_ADC16_HAS_CALIBRATION */
   adc16ChannelConfigStruct.channelNumber = DEMO_ADC16_USER_CHANNEL;
   adc16ChannelConfigStruct.enableInterruptOnConversionCompleted = false;
#if defined(FSL_FEATURE_ADC16_HAS_DIFF_MODE) && FSL_FEATURE_ADC16_HAS_DIFF_MODE
   adc16ChannelConfigStruct.enableDifferentialConversion = false;
#endif /* FSL_FEATURE_ADC16_HAS_DIFF_MODE */

but how to init the channel se4a, channel 4b,channel se5a, channel se5b etc

how to init the channel DM0, channel DP0 etc (the same using as channel se0)

or how to init the temp sensor?

Thanks in advance!

Hi, Jack,

I think You can call the following function in this way:

ADC16_SetChannelMuxMode(ADC0,kADC16_ChannelMuxA); or ADC16_SetChannelMuxMode(ADC0,kADC16_ChannelMuxB);

Hope it can help you.

void ADC16_SetChannelMuxMode(ADC_Type *base, adc16_channel_mux_mode_t mode)
{
    if (kADC16_ChannelMuxA == mode)
    {
        base->CFG2 &= ~ADC_CFG2_MUXSEL_MASK;
    }
    else /* kADC16_ChannelMuxB. */
    {
        base->CFG2 |= ADC_CFG2_MUXSEL_MASK;
    }
}
