The available GPIO pins are becoming more and more restricted and especially with the changes required by Pi5 they ain’t really the most reliable mechanism.
I’ve had to alter my early zynths twice because pins I’d used were swallowed up by some lower level Pi mechanism…
And once you add the number of buttons that the v5 Zynthian uses it becomes easier to pass off the functionality to something external probably running off 12C… This is how things develop. IT also becomes a little more side stepped as the API develops.
Such is progress.
Here’s some early wyleu GPIO efforts…
