Sorry not to be clear. I would love to provide a minimal example, but the problem is I can't trace the exception to the line it originates from, so I can't recreate a simple example from the problematic code. Any ideas?

Hi all, The medea low-memory JSON parser I developed in Micropython for ESP8266 has stopped working since v1.10. I'm struggling to know how to modify the library to satisfy the requirements of PEP479 which was brought in by 1.10. This means all cases where I use nested generators now terminate in a ...

Have you tried running each of these commands or code blocks through the REPL? This means you can interactively see any errors or blocking statements (which don't return to the REPL prompt) and figure out what is behind the error. Another thing I do within the boards I use is connect over serial, th...

And take a look at https://youtu.be/-MrqCmq3Z5k?t=18m4s for a walkthrough in answer to your question "understanding how the C source get converted in to Python libraries. Where can I look to get a better understanding of this?" which starts by looking at the modmachine.c source

What kind of editor are you trying to use, for which pylint is a plugin? There are editors like Thonny and Mu, and a plugin for PyCharm which are all cross-platform, free to download and install, which I would expect should recognise Micropython libraries, as they target Micropython specifically. I ...

According to https://forum.micropython.org/viewtopic.php?f=6&t=4410&p=25630&hilit=deque#p25630 there is a deque implementation which may be useful for managing a queue where you are putting values in one end and removing on the other.
