analogRead() sample rate Cubecell AB01

#1

Greatings,
When i try to visualize the sampling rateof the ADC it looks like is only 100 Samples per second, the theoretical speed is 1MSample per second, so something is wrong, how can i change the sampling speed? i need at least 50KSamples per second.

Have the same problem here, have tried changing the registers of sampling speed but doesn’t seem to work.
