Can the microphone input with headset control functions (e.g. play/stop, volume increase and decrease) be connected to both the Codec ADC (MIC input) and normal SAR ADC input pins in the NuMicro® NUC505 series? Can a key or which key is pressed be effectively and accurately determined by a specific voltage level? Datum:2016-11-29
Connect the microphone input with headset control functions (e.g. play/stop, volume increase and decrease) to both the Codec ADC (MIC input) and normal SAR ADC input pins in the NuMicro® NUC505 series. The following figure shows the application circuit connection.
The following table shows the SAR ADC samples that are actually measured when a key or no key is pressed. It is possible to determine whether a key or which key is pressed according to a different SAR ADC value.
