I was trying to use the sx1509 with esp-32. I make the connections according to I2C and then upload the analogWrite example. However, the innitialiation function
does not work (i.e the expander is not innitialised). I checked in the .cpp file of the library. The
statement returns false.
Note: the board works perfectly with arduino MEGA.
Can anyone please help me solve the issue (or at least give a hint of what the problem could be).
