Is there a particular reason for dsPIC33? Wouldn't a PIC32MX (even available in DIP package) or the newer PIC32ZX be better suited?

This issue seems to be fixed in recent Micro Python versions.

It's an open bug:

Just for completeness, here is the code without the big string concatenation. However, it still runs 2.5 times faster with the explicit call to gc.collect() in place. # MicroPython example for controlling one WS2812 LED. # Method similar to http://www.espruino.com/WS2811 import pyb from pyb import S...

nice.

In the video there seems to be an irregular refresh rate. Maybe you can try adding
in the loop somewhere. It solved my issue with random garbage collector related delays (http://forum.micropython.org/viewtopic. ... t=108#p580)

@fma: Are you going to share your modified code or not?

Please attach the code.

Hi,

will the PYBv1.0 EAGLE files be uploaded to the pyboard repository on github?
