MicroPython Forum

No, it doesn't on mainline MicroPython. PR's welcome! I have taken look at the SSH implementation on the Lobo port; effectively libssh2 was embedded inside the Lobo port. I'm not 100% clear on using a 3-clause BSD license inside an MIT project; there may be concerns there. That said the implementati...

"hard to know if such code was/wasn't influenced by GPL code", that's silly. You could say that about any code anywhere. I think it's just a weak excuse for NIH. At the time this was a very legitimate concern. Loboris had claimed his repo was covered under the MIT license yet there were clear uses ...

Has anyone tried Rocky's port enough to give any feedback on it?

Interesting quotes from the forum link: > > They also said at the time they were going to support MicroPython, but not Adafruit's CircuitPython. > Our decision to stick with Micropython is to credit the huge work the MicroPython team has done putting it together and help them grow their project cont...

Provides an average frequency output of 237 kHz for an expected frequency of 250 kHz. Increasing p_size allow you to get closer to the expected frequency, but uses more memory. By analyzing the frequency spectrum, a second frequency appears at high frequency. It is related to the loop and the size ...

Hiya safetyfactorman, Thanks for sharing your thoughts! I think that micropython is headed towards some kind of relationship with the IEC61131-3 world. I think that if micropython becomes an IEC61131-3 language, that it will revolutionize both the IEC61131-3 standard, and micropython. What leads you...

OK now I am super super interested it appears that RMT should be capable of driving steppers very well. It's one of the use cases I hope it will prove useful for. Driving Neopixels is another... OK a python function can simply generate the step timing needed for the acceleration write it to a list ...

I've created a class to drive multiple stepper axis using RMT. https://gitlab.com/olivier.len02/micropython-multiaxis So far, the max frequency I can rich is around 17kHz. Is there a way to improve the step frequency? You're only using RMT to send a single pulse at a time - see where you're sending...

Do you know if the SAMD support will cover the Metro Grand Central? That would be awesome.

The Grand Central M4 Express is a SAMD51 so yes, it will be a goal to make the port work on it! I don't have one so it'll be great if you could test with yours.

I enjoy the SAMD support. It will be possible to upload MicroPython on Feather M0 Express (from Adafruit) instead of CircuitPython. However, it will be necessary to compile the SAMD firmware... I've been able to run the MicroPython SAMD port on a Trinket M0 and an Itsy Bitsy M4. But, to be clear, a...
