Hi guys,

     I am a beginner and just start playing around with the board. I need some help on configuring 2 analog inputs for adc3. I already looked at the peripheral example. It seems like it is only configured for 1 pin. Also, I have a question regarding to the adc dma example. In the example, PC2 is configured as an analog input. How do you know that PC2 is connected to ADC3 channel12? If i have 2 analog inputs, do I just pick random 2 pins and hook it up 2 random channels? By the way, I am using stm32f4discovery. Please advice. Thank you.
