I'm trying to implement a simple software SPI for the Teensy 4.0 and I am looking for a way to get a very short delay of at least 25ns but optimally less than 100ns with something similar to delayMicroseconds. Is this possible, or is there a better software SPI solution already available.
I can't use the hardware SPI pins because of the way my project is already laid out.
