Setting GPIO pin as output pin

Masaking1904 · October 2017

I am poor at English, so I am writing the following sentences using google translation.

Greetings,

I have the Cyton board with the Daisy module, 16 channels. It is already possible to measure brain waves at 16 places using OpenBCI GUI.

I'd like to use the Cyton board's GPIO pin for output.

Is there a way to output digital output or analog output from GPIO pin while measuring 16 brain waves with 24 bit resolution?

Anyone please advise.

Thank you,

Hi @Masaking1904

There are five digital outputs that you can control. They are controlled using digitalWrite() which is described in detail over at Arduino docs: https://www.arduino.cc/en/Reference/DigitalWrite

You can set the pinMode(OUTPUT) and then specifiy the GPIO pin to control with digitalWrite(17) for example. The possible GPIO pins are 11, 12, 13, 17, and 18 which are visible on the top of the Cyton.
