#53591 Maybe people should start testing their code and see if anyone can get good performance with latency on I/O reads!!!!

If you do any tests post them in this thread.

#53598 I don't think it fruitful to continue to seek this path since the combination of the GPIO being behind the AHB? bus and there being no mechanism in the LX106 to continue issuing instructions while the read is going is a pretty conclusive "NO."

Perhaps there may be some other side-channel. vinouz on Twitter suggested multi-wire SDIO, but even that is awkward. Espressif have been very, very helpful! I don't think we should continue to badge them on this front.

Perhaps on the ESP32?

#53613 So as it sits now with the large delay, would it work at all?? would you just get 3mbps instead of 12mbps, this is still better than zero :-)

And "YES" Espressif has been very helpful! Thanks!

#53622 It is all or nothing. If you even have a small hiccup, or anything, gotta ditch the whole packet. It is quite annoying. But, who knows, maybe someone will yet find a way. Just doesn't sound likely at this point.

I still super have my fingers crossed for the '32!
