analogin EFM32HG-STK

Hi,

I try to use PE11 on the Happy Gecko STK as an analog input. According to the web description: https://developer.mbed.org/platforms/EFM32-Happy-Gecko/ PE11 is an analog pin, but this is not the case in reality, so it will end up in an error.

So this is not a bug in mbed, but in the web description. Please update this so others won't develop hardware with wrong connection as well.

Cheers.

Hi again,

According to the data sheet of the MCU, PE12 and PE13 are ADC channels. However, mbed still throws an error if configuring these pins as AnalogIn. Why is that? Are they internally configured as something else? Can I somehow get them to be an AnalogIn pin?
