Using QN9080 part.
PA06 labeled ADC_EXT_CAP..implies I need to place a cap on this to use internal ADC, yet there is no explanantion in data sheet or user's manual for this..so DO I need a cap or Can I use this as a GPIO and still use ADC?
Could you please share with me where are you seeing this label? I was not able to locate any reference to it
QN908X data sheet rev 1.2
page 11. pin description
PA06 in Alternate function col. ADC_EX_CAP
also look at Dev kit schematics and you will see a cap on this pin.
