Probably a stupid question from a software guy:
While driving an optocoupler I have to limit the input below 5mA (or 10mA or even 20mA depending on the teensy), this by adding a current limiting resistor.
Can I combine 2 digital output's with there own current limiting resistor to deliver more mA to the optocoupler?
