voltage measurment using stm32f207vc ADC

[rukmal1992]

how can i find the exact analog pin of stm32f207vc... since the analog pins are not specifically noted in the data sheet..

plz help me..

In the "Other Functions" Box on the right it states ADCx_INx.
Then look under "PIN NAME" and find the name that corresponds.
Find a picture of the chip like so: http://www.wvshare.com/img/pinout/STM32F205-207VxT_l.jpg
Then find the pin on it and use it. Trace tracks if you don't know your board.
