Is there a way to configure a Teensy 3.2 A/D 'x' pin to become a switchable ground without adding an external transistor (ex 3904)?
For example:
If I have a sound board that needs pin x grounded to trigger a file play, is it possible to configure the Teensy 3.2 to use say pin 18 to switch to ground when 'activated?' (it would go from neutral to ground) I do not know if there are any built in transistors on the Teensy that can be configured to work with the specific pin like this.....(this is different than pull up or pull down resistors)
Thx
