If you are confident in understanding how MP works you could implement the Neoplixel driver I made using a timer interupt to send the data. See here https://github.com/OutOfTheBots/STM32_NEOpixels_timer It has been tested on a STM32F407 there might be a few small tweeks for it to do eactly what you ...

From the googling that I have done this seems to be the most common method for creating neopixle timings. basically work out how many NOPs are needed to get correct timings. Although it gets the job done it isn't very flexible to be able change the timings or running on different CPU freq MCUs. You...

I have build an omni directional robot that can move with 3 DOF (x linear, y linear and w rotation). I do have another video (on my youtube channel) where I explain how I work out what speed to drive which motor to give me the desired x, y, w speeds. I have now worked out how to keep an accurate dea...

There has been a few times where people have asked about functionality for using steppers in MicroPython. Atm there isn't any real way to do this because speed at which the ramp up and ramp down step pulses need to be generated at. I have made public my basic C code for being able to generate steppe...

I use dfusedemo from ST to flash .DFU files to STM32 boards under windows

I do believe some people have started some support for these boards too https://www.aliexpress.com/item/4000300005466.html?spm=a2g0o.productlist.0.0.78504a2b7ZvFMi&algo_pvid=c6eab1dd-8940-4c9f-a358-6b1a58a69915&algo_expid=c6eab1dd-8940-4c9f-a358-6b1a58a69915-1&btsid=0ab50f6115945021843615388e8d7d&ws...

It is certainly a nice direction for Lego to be moving in.

Thanks for both your work and for posting here. I for 1 have been very excited about Lego move into MP as I own 4 EV3s and my older kids used them to learn robotics and compete at robotics comps but ended up moving away from Lego because having to use the Labview programming environment. I did insta...

I put a schmitt trigger in front of every button and encoder signal I have. So for me it's the perfect solution now. It's maybe a good idea to put a example code into the wiki? I am curious if a schmitt trigger will work to remove switch bounce as the signal bounces all the way from total open to t...

Ok, we're talking about different encoders and different uses here. My experience is with using encoders for controlling user interfaces, e.g. in place of a potentiometer. These are encoders that come for 5-8 bucks for 10 pieces. Ahh yes those use mechanical switches that bounce a lot but only turn...
