Re: Fast RGB to HSV (And vice versa) calculations?

According to the forum post native and viper decorators on the ESP32 neither decorators are available for the ESP32.

It's possible that it has been added to the ESP32 port since that post but I couldn't find anything obvious in the codebase that made it clear...

Re: Fast RGB to HSV (And vice versa) calculations?

Viper is great - unless you want it to work on multiple ports. Most of my development is on the ESP32 right now where there is no Viper implementation...

Re: Fast RGB to HSV (And vice versa) calculations?

Completely understand; so perhaps start with trying to apply the MicroPython performance suggestions. I'd like to tackle implementing it as C module but spare time is currently in desperately short supply! I'll bump it up the priority list and try to get to it... In the meantime, please keep us post...

Re: Fast RGB to HSV (And vice versa) calculations?

I suggest first taking a look at Maximising MicroPython Speed to determine if you can apply any of the techniques there to improve the performance in MicroPython. Damien's PyCon AU talk on Writing fast and efficient MicroPython is full of useful tips too. Some of those may help get performance to an...

Introducing the TinyPICO

Hi folks, Way back in September I posted that Seon ( @seonr ) and I had begun development on a small ESP32 board that was breadboard - and MicroPython! - friendly. The design has been improved and refined over a number of revisions - in no small part due to the excellent feedback we received from th...

Re: Something like Threading/Queue in MicroPython?

Without knowing your use case, it's hard to say what the right solution is - but asyncio is a fair bet. ;) Peter Hinch has implemented Queue for asyncio. Check it out and see if it fits. Threads are possible but they come with added complexity and a less mature implementation (no threading library o...

One of the people in the meetup was super interested in this library as they are looking to use the ATECC508A... @OutoftheBOTS_ a like button wou...

Re: fastest way to fill large bytearrays? (Neopixel, APA102 et al)

Also, if you are using APA102's you might want to take a look at my micropython-dotstar library. As discussed in this forum post, @bill-e was able to update 3000 APA102's in about a second using it. Hope that helps!
