BUT: i want some fast ADC data, so the arduino "analogRead(A5)" is much too slow. (about 10 ks , i want 800 ks , what should be really no problem for 5 Ms ADC.)
now...tried to do a call to HAL functions , to get fast data from adc....but this i didnt get to any working output.
so: how to do a HAL call , working (!!!) (yes, the "Correct usage of HAL functions in Arduino code" and others i was reading - but there is no working example !! more discussion about sense or nonsense of 32bit cpu in arduino...not very helpful. )
so please, can anybody show me, how to get some working HAL calls to arduino?
here is, what i tried in arduino:

HAL_ADC_Start(&AdcHandle);
while ((HAL_ADC_GetState(&AdcHandle), HAL_ADC_STATE_READY) == 0);
adval = HAL_ADC_GetValue(&AdcHandle);
