I tried to get A1 pin voltage on my stm32f2xx with ADC.
I have always the same value (3300mV) for temperature sensor, Vbat, VrefInt and A1 Pin ...
I used ADC VBAT_Measurement and ADC3_DMA examples of STM32F2xx_StdPeriph_Lib and I read always the same value.
If someone has a solution to fix this problem.
