Doubt about this ADC block
This is the Analog Input block (Embedded→STM32→ADC→Analog Input). The docs says it output between 0 and 1, this doesn't seem to be the case I tried reading a sine signal (0 to 3 ) using the simulated analog channel block. The output of the Analog input block also outputs sine (0 - 3). Why is the block outputting 0 - 3 and…
