I am trying to get the temperature from the internal temperature sensor in mcbstm32f400 having stm32f407ig. i read the manual too which i found where its configuration is mentioned but not in detail like the temperature sensor is connected to adc1 ch16 but how to enable ch16 is it connected to some gpio pin or directly connected internally to adc in that case we dont have to configure ports , how to give clock to it and what frequency of clock .Please provide some detailed guide or reference or example code(i dont want the whole code but some guidance)
None of this has anything to do with Keil - it is all ST-specific hardware details.
Look to ST for examples of how to use their parts ...
"how to enable ch16"
Exactly the same as enabling any other channel?
