I have a BananaPi M2 on Bananian 16.04. Before install this, I run on raspbian with BPI-WiringPi. When I’m on raspbian, the GPIO output sent 3.3V. But since I have install bananian, with the same BPI-WiringPi, my GPIO sent 1.6V. Why this change? There is a voltage divider control by software ? How can I configure this ?
I didn’t find the right solution from the internet.
