Thanks for testing this out! Really appreciate it. First thing to try would be to use hardware SPI if you're not already. I'll need to check the Huzzah32 pinout but some ESP32 pins can support much higher SPI transfer rates; APA102's should be capable of 10's of MHz (the ESP32 can transfer SPI at a ...

Hi Zoltán, I haven't got a lot to offer right now but I'm super interested in your work! I've been experimenting with rendering to displays in MicroPython - including fonts - for a while now. Designing the right levels of abstraction is not easy; I'll try and provide some feedback when I have a chan...

I've just published the MicroPython DotStar library. It's a straightforward port of Adafruit's CircuitPython DotStar library. Which was originally a port of a MicroPython Neopixel library - it's come full circle! Previously APA102 control was only supported via a port-specific module on the ESP8266 ...

mattyt , are you sure you knock on the right door? Did you read the post above at all? Did you read the links in it? Yes, I had read the entire sordid mess. I'm well aware that I'm "knocking on the door" of the person who just willfully broke mainline MicroPython. Again. I'm going to have to take a...

Hi Larry, I'd suggest porting; the only difference is in the I2C driver. Take a look at MicroPython's I2C interface . Typically you should expect the I2C device to be created and passed in to your class, then just use the 'Standard bus operations' to read/write. The context managers (with device as ...

Heya Daks, Most of your questions can be answered if you take a look at Deshipu's code . It's only around 100 lines and very readable (I especially like the use of the partial functions Deshipu!). The example in the docstring should be particularly useful to you: import bno055 from machine import I2...

Currently upip can only install the latest version of a package. See upip.py:175.

I'll try and raise a pull request to allow different versions to be installed.

In the meantime the workaround is to simply download the library you require and copy the files to your device.

The documentation about that for ESP32 is pretty sparse. Tangentially...Note that I've made a start on the ESP32 documentation. You can view it or contribute via a pull request. I've just created an issue: Need to improve ADC documentation . If someone could submit a PR that'd be great! Otherwise I...

RMT transmit is coming along (I've started some very rough testing locally but am not happy with the API yet) but I haven't started on the receive side. I ought to have something good enough to share in the next couple of days for transmit. It should be possible to do some quite accurate pulse measu...

I agree that it should be consistent @OutoftheBOTS_ and have raised #4379 to cover the issue.

I'll add it to my list...
