Re: Ultra-low latency GPIO interrupts?
Posted: Sat Jul 30, 2016 11:25 pmThat's pretty cool! I wish I saw that before I got all my stuff going. I had to find some of those things on my own. I am trying my best to get usb1.1 full speed working, though - which even if I coded the logic in ASM wouldn't be close to fast enough. I am trying the same trick I did with Ethernet and SO FAR it looks sufficient.
All of everything past usb1.0 (and even usb1.0 if I want it reliable) utterly hinges on low-latency nmi interrupts.
I've been clocking my code with the ccount thing (dude, that is so cool!) Thanks, jcmvbkbc!
