Do you happen to be using an ESP32? There's an issue on that port that many Neopixels behave similarly to what you describe unless you pass a 'timing=True' when you instantiate the Neopixel class. See #159 on the old ESP32 port repo for details. So try something like: pixel_strip = neopixel.NeoPixel...

The error is misleading but I've come across it before; I see it when there is no internet connection.

To connect to your wifi:

Code: Select all

import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('YourWifiSsid', 'yourwifipassword')

I've recently been playing with Unexpected Maker's Neo7Segment displays. They're a neat 7-segment module made up of NeoPixels. So now there's a MicroPython driver for the Neo7Segment . :) It's bare-bones at the moment; I intend to improve the encapsulation of the segment mapping, add colour fading a...

@pythoncoder's suggestions are, as always, excellent. In particular, a lot happens under the radar amongst the issues in Github . I'm not one that typically learns well from video's but a few things clicked when Damien George - creator of MicroPython - presented how to Wrap a C module in MicroPython...

`ntptime` is alluded to in the ESP8266 docs but, you're right, it's not been well documented. As best I can tell it's only in the ESP8266 and ESP32 ports (and a different implementation in the Loboris fork as Dave mentioned). Since it's a pure python implementation it could be easily added to any of...

There is primitive NTP support in the ESP32 port (borrowed from the ESP8266 port). In short:

Code: Select all

import ntptime
ntptime.settime()  # Synchronise the system time using NTP

Caveat: There is no timezone support so the system time will be set to UTC.

We recently recorded Damien giving a talk titled Wrap a C module in MicroPython at our June Melbourne MicroPython Meetup. Sounds relevant for what you're asking!

@deshipu also wrote some MicroPython Development Documentation that covered similar ground.

I hadn't - and it looks like a neat addition. Thanks @pythoncoder!

Sounds very much like flow control, as @Roberthh mentioned.

To clarify, Flow Control, in the Connection/Serial category, needs to be set to None:

It looks mostly correct @deshipu. The only point that jumped out was the directories have changed a little (specifically: ports are now in ports ). I raised a quick PR . And although perhaps not finished , it's a valuable resource! As time allows I'll be sure to update it rather than create my own.
