I am using nucleo-g491re and i was unable to use prescale of 1 asynchronous for my ADC. the solution, on this site, was to change VSO0 to VSO1 but it seems my board has no such option. only to boost (whatever that means). So how can i get the maximum possible 170Mhz for my adc (if possible). Its not strictly required as the ADC sampling needs to be done and transmitted at 10 kHz only roughly. (actually now that i think of it, i think its not needed to sample at high frequencies because i also need to send to another device as well, and that has a very much lower frequency for sending data)
1. So you have vso1 now anyway - whats the problem then ?
2. > get the maximum possible 170Mhz for my adc
see ds, whats max frequ for adc...
(here from G474 / 170MHz core )
3. >transmitted at 10 kHz only roughly.
So you need faster than - lets say : 10us conversion, whats no problem for this adc.
see ds for conversion time vs adc-clock .
