I'm designing a PCB for a project for massive amounts of I/O for a T3.5 and was wondering about secondary ports. For instance, the pinout I have says D26 can be used as an alternate for TX1. Does that mean if I do Serial1.println("hi'); in my code, will D26 output a waveform by default?
If not, how can I configure the Teensy to output on the alternate pins and not the primary pins?
If so, how can I configure the Teensy to only output on the primary pins? For instance, if I have a device connected to the primary Serial1 pins but want to attach a servo signal wire to D26, what do I have to do to make sure I don't accidentally send a serial command to my PWM servo?
