SDN Pin missing from initialization #12

Closed harpekar closed 6 years ago

The SDN pin must be pulled high in order for the board to not be put into Shutdown mode, as stated in the datasheet on page 19.

Recommend adding 

pinMode(SDNBAR, INPUT);
digitalWrite(SDNBAR, HIGH);

in setup(), with SDNBAR being the Arduino pin that indexes SDN.

The SDN pin has been already pulled up with R15 so there's no need to pull up in code.

Thank you for your suggestion. This does not seem to affect the functionality of the circuit described in the hookup guide. If you are still having issues with this and have further questions, please contact our Technical Support Team.
