Measuring Temperature without Vref external!

Question asked by disperse on Jul 12, 2012
Hi All,

I'm using STM8L152R8 for an application and I need to measure the temperature by ADC but the problem is the external reference voltage has to be off for some cases and in these times I need to get temperature without using external reference voltage for conversion. Is there any proper way to use internal reference voltage as a reference for ADC? Apparently, This MCU doesn't have such a feature but I'm wondering any other way might be possible?
Any help will be appreciated.

Thanks in advance,
