Are the 6 fast channels on an STM32h742 ADC preconfigured by default as fast or I need to configure them as fast?

2021-04-07
I have the package LQFP100, so the Application Note specifies that there are 3 fast channels, but the Reference Manual says that the first 6 input channels are fast channels. How is this? If I have to configure them as fast how can I do it or where c...

Which is the maximum sampling frequency of ADC? STM32H742

2021-04-06
I am trying to configure STM32H742 to convert 3 different input channels (3, 5, 16) in an ADC (1) . I have achieved to convert just one channel with a sampling frequency of 1MHz, seeing that 1 million samples are converted per second. But when I add ...

Using an ADC how can I make the value of Vref- depend on the value of another input on a STM32H742 chip?

2020-10-13
I need to implement an ADC to measure phase voltages, so I want to set the N phase as Vref- and get the values of other 3 phases (comparing with N phase) on the output of the ADC. I am using single-ended mode.Is it possible to do this? How can I do i...
