Thanks I knew there was a simple line of code.
Iāve often thought that there should be an API to fetch all the digital pins at one time, on smallish arduinos (nominally 14 bits, and another call to get the 6 analog pins.)
It could get relatively complex when the pin mapping is strange (say, nano every), but you could get away with a lot of strangeness and still be faster than 14 calls to digitalread.
