Anyone know how to use PTE29 or uC pinout #13 on the Teensy-LC? Just as a simple output digitalwrite type High or Low...
LC uC Pin 13 aka PTE29 as GPIO Output High / Low

But digitalWriteFast(), especially when use with a const parameter, does the same.

Sweet. Thanks.
I think I got it. Was seemingly easiest to "re-map" an unused pin from the same port (port E) to the PTE29 pin.
For me, it was PTE30 to PTE29.
I changed 2 things in core_pins.h and I believe it worked.
Changed #define CORE_PIN26_BIT 30
to #define CORE_PIN26_BIT 29
Changed #define CORE_PIN26_CONFIG PORTE_PCR30
to #define CORE_PIN26_CONFIG PORTE_PCR29
And now PTE29 can be accessed via the name '26' , like digitalWriteFast(26, 1);
