Re: MLX90621 hardware

Over at OpenMV they have a thermal shield that uses the MLX90621:

with the Micropython code in their GitHub repository:

I've used the MLX90621 with the code and it works well.

Re: Developing MicroPython libraries for different boards

In order to have a common code base across a number of different boards using the SAMD21 processor, Adafruit seems to have decided to make a permanent fork of MicroPython. In this fork they've depreciated the machine module, and implemented two modules for hardware abstraction ( board and microcontr...

Re: Suggested standard approach to font handling

How different is your Python font file format from the format used by Teensy & Adafruit for the ILI9341 font files (in C), if this is a quick question to address? The reason to ask is that there may be fonts already optimized for small screen readability in bit-mapped format, that might just need th...

Re: The state of the community

Another measure of the Micropython community: Of the posts to the micropython.org forum, over 55% have been generated by 15 individuals. Three of those are Damien, Paul, and Pycom. I suspect that there are many other lurkers ('guests') like myself, frequently, trying to get up to speed. For us, thes...

Re: Avoid flash wearing by altering behavior originally introduced by Espressif (the inventor of the ESP8266)

I’m mostly ignorant on the subtleties of the network protocols. After reading through this discussion; reading the FAQ at the top, reading the documentation (docs.micropython.org/en/latest/esp8266/library/network.html) and: also those on Github: EPS8266: No automatic reconnect after WiFi activation ...

Re: DS3231 precision RTC driver

Some feedback on @pythoncoders RTC routines -they are excellent. I compared the calibrated pyboard v1.0 internal RTC (with battery backup) to three versions of DS3231 based boards; a ChronoDot 2.1 and two $3 ebay versions. All have the extended range DS3231SN chip. The DS3231.calibrate(minutes=10) r...

Re: New semantics of utime.ticks_diff

Thank you, @pythoncoder, for noting the change and for providing the code snippet. If you don't mind, would you post the link to the related Github discussion? When I see a reference like yours, I try to find the discussion as a way of practicing my Git-fu. This time I'm unable to make the link... (...
