Stewart Russell<p>I forked this excellent multi-precision maths library to give it explicit support for CircuitPython:</p><p><a href="https://github.com/scruss/micropython-decimal-number" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/scruss/micropython-</span><span class="invisible">decimal-number</span></a></p><p>So it you're finding single-precision a bit cramped, give it a shot.</p><p><a href="https://xoxo.zone/tags/CircuitPython" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CircuitPython</span></a> <a href="https://xoxo.zone/tags/MicroPython" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MicroPython</span></a></p>

I have an #ESP32 programmed in #micropython that wakes every five minutes to check the temperature of a water tank.

If the temperature (or it's battery voltage) drop below certain level, it texts me. Otherwise it goes into deepsleep for another five minutes.

All this is powered by a 3.3V 400mAh Lipo battery. I set it going on Aug 1st, and I've just had a text to say it's battery is low - 50 days!

It was challenging to design such a small modular #3Dprinted #robot for #PiWars in 2024. I have started to work on the code again as so much was unfinished for the competition. This was my first robot using a #RaspberryPi 5 and my first robot with encoder motors. I wrote mechanum mixing with IMU support in #Micropython for the Motor2040 board, which the Pi5 talks to over the USB lead. After some work to better comment the code I have finally published it on github.com/Footleg/PiWars2024

anecdata

It would be nice to throw an RM2 onto any of the WIZnet EVB-Pico2 (W5100s, W5500, W6100), but the standard Pico pinout doesn't expose the pins that are baked in for Wi-Fi.

I think there's now support for alternate wifi pins in #micropython

There's an enhancement issue filed for CircuitPython: github.com/adafruit/circuitpython/issues/9777

Another thing I'm a big fan of is MicroPython! ManT1S will ship with an OTA-capable #MicroPython runtime pre-installed, with WebREPL enabled out of the box. This means that you can load files and get a console over the network when you use the ManT1S-Bridge! It's hard to beat the convenience of connecting your device, popping into a #shell and interactively playing with the #hardware to get started.

In a Linux shell, the following command is executed: ./webrepl_cli.py mant1s-678756 After password prompt and typing in the password, a MicroPython shell appears. Then the commands: import sys sys.version Respond with: '3.4.0; MicroPython v1.26.0-preview.158.g5cfafb73d on 2025-05-28'

Quickly adds another slide to his presentation showing teachers how to downgrade an Arduino Nano ESP32 #MicroPython image using the Arduino Labs MicroPython Installer. 🤣

Here's how:

Get the app-bin firmware from: micropython.org/download/ARDUI

Next:
1. Tap-tap the on-board button (at about the speed you read tap-tap). The RGB LED colour cycles.
2. Tap the on-board button again. The RGB LED pulses green.
3. Drag and drop the app-bin file (not .uf2 like RP2) into the Installer. 😊

So, I'm presenting a workshop for teachers on the Arduino Nano ESP32 at the CEMC conference on Wednesday, and the fresh new #MicroPython 1.26 breaks simple example code. 🤷

This works just fine in 1.25. Has anyone else had problems with 1.26 and this (or other) microcontrollers?

A screenshot of a short, 15-line MicroPython program designed to configure Arduino Nano ESP32's built-in LEDs and blink one of them. When run, it fails at line 19! I did not choose the randomly-generated file name assigned by the Arduino Lab for MicroPython IDE, but I'm certainly enjoying its prescience. ;)
