AnalogIn Diff on the FRDMK64F ?

Hello

how to use SIM_HAL_EnableAdcClock () function?

how to use BW_SIM_SCGC3_ADC1() macro ?

Thank you.

my code

AnalogIn_Diff::AnalogIn_Diff(int a2d_number) : ch(a2d_number)
{
    SIM_HAL_EnableAdcClock(SIM_BASE,ch);

    BW_ADC_SC1n_DIFF(ch, 0, 1);     //  Differential Mode
    BW_ADC_CFG1_ADICLK(ch, 0);      //  Bus Clock
    BW_ADC_CFG1_MODE(ch, 3);        //  16Bit differential mode
    BW_ADC_CFG1_ADLSMP(ch, 0);      //  Short Sample Window
    BW_ADC_CFG1_ADIV(ch, 3);        //  Clock / 8
    BW_ADC_CFG1_ADLPC(ch, 0);       //  Normal Power Mode
    //modif
    // BW_ADC_SC2_REFSEL(ch, 1);//internal sources depending on the MCU
}
