Nuvoton M487 ADC Accuracy using AnalogIn() about mbed-os HOT 4 CLOSED

To extend M487 EADC sampling time like below,

//--------------ADD THIS LINE OF CODE TO IMPROVE ACCURACY---------------------   
EADC_SetExtendSampleTime(eadc_base, chn, 0xF);  //ADC produces much more accurate readings when this line is added. at least 0xF of extended sample time is needed. more is better.
//----------------------------------------------------------------

This can be done through M487 target configuration:

For example, in mbed_app.json, add below to extend EADC sampling time for AudioIn A0/A1 pins.

{
    "target_overrides": {
        "NUMAKER_IOT_M487": {
            "target.eadc-extsmpt-list": "{A0, 20}, {A1, 21}"
        }
}
