MicroPython Forum

Excellent question: as the parent of a 9-year-old I've been curious about these lego/micropython bricks for a while now, but from reading official descriptions it was never entirely clear how this differs (or not) from a lego-less microcontroller. So I'm also interested in a good place to learn more...

I've always been amazed that it's possible to align the wbus connectors with the required degree of precision. Two comments: first, the WBUS pads are only 200 microns wide, so a reasonable visual alignment (using a binocular scope) is likely to be good to 20 microns or better, which is really not t...

Hi all, I understand Peter's reluctance to design a DIP32 based on the WBUS connectors, but in case someone finds it useful, here's my attempt at something like that: https://github.com/mdaeron/pybd-breakout . The soldering wasn't too hard using low-temperature solder paste, an adjustable heating pl...

This is a very non-specific answer, but you could look at pyb.USB_VCP() and set up some flavor of two-way communication between the host computer and the pyboard.

This won't give you an error, however it doesn't function properly. I think there may be a bug in the .tobytes() file as the lenght of the array is off by a factor of 8 (the size of float object).

You could try again, this bug was just fixed a couple of hours ago.

By the way, I've been playing with the EasyDriver recently (but managed to fry one), as well as this one: https://www.pololu.com/product/2966 . Does anybody have an idea of what differences exist between these two options? The second one is cheaper and smaller, what would I be getting by opting for ...

Did you try replacing by or something like that?

Thanks again Peter. I only very recently started to experiment with at asynchronous coding, so this is helpful. I'll be trying to implement all I need without timers, if only as a learning experience. In case anybody is interested, I'm a stable isotope geochemist and this project aims to design from...

Thanks Peter for pointing me to that. I'm trying to make this work but my UART device (MKS 910 pressure/vacuum gauge) seems to communicate without ever using newlines: all communications are of the form "@254_;FF", with the underscore replaced with the actual content of the message. I tried calling ...

I have prior experience with pyboard Timers and I'm currently learning my way around the uasyncio library. Are there general recommendations as to how these two things work well (or not) together? For example, suppose I wanted to repeatedly write to a UART device, wait for a fixed delay and read fro...
