Same issue here on an ESP01S. What might be of interest is that once I create the problem (by attempting to connect to my wifi network), it persists after physically switching the power off and back on again. Only way I've found to make the problem go away is to re-flash the firmware (this is on μPy...

You might have already seen this, but https://github.com/miketeachman/micropy ... s-examples seems like a good place to start.

I'm wondering if significant changes have happened re: this issue over the past 4 years. My use case is that I have time-critical (pushing data to an I2S amp) and non-time-critical (monitoring gyroscope readings and various switches) coroutines, and I'd like to prioritize the former. What happens wh...

To expand on pythoncoder's answer, I think the real hard part here would be to read "on the fly" or to store in memory 20 mn of non-repeating music, at a reasonably good sounding bitrate. If a lot of the audio is repeated (e.g. mixing single-tone piano notes with short percussion clips and one or mo...

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 ...
