📟 ESP32/ESP8266 MicroPython Web Server – Control Outputs

Learn how to build a web server to control the ESP32 or ESP8266 outputs using MicroPython framework. As an example we’ll build a web server with ON and OFF buttons to control the on-board LED of the ESP32/ESP8266. We’ll use sockets and the Python socket API.

💻 CanoPy

Canopy is a visualization tool for plotting CAN bus message payloads

A basic PC CAN interface simply dumps the bus’s message traffic into the terminal, while more sophisticated tools organize messages by the address of their intended recipients. Both of these approaches digitally lift the hood and let you examine what your car is thinking, but the wall-of-numbers approach makes finding the patterns that hold the keys to reverse engineering difficult.

Automatically plotting the data with CanoPy makes finding correlations much easier, after which the text-based tools can be used to focus in on a few specific addresses.

🤖 An Introductory Robot Programming Tutorial

In this article, I’m going to show how to use a Python robot framework to develop control software, describe the control scheme I developed for my simulated robot, illustrate how it interacts with its environment and achieves its goals, and discuss some of the fundamental challenges of robotics programming that I encountered along the way.

In order to follow this tutorial on robotics programming for beginners, you should have a basic knowledge of two things:
▫️ Mathematics—we will use some trigonometric functions and vectors.
▫️ Python—since Python is among the more popular basic robot programming languages—we will make use of basic Python libraries and functions.

The snippets of code shown here are just a part of the entire simulator, which relies on classes and interfaces, so in order to read the code directly, you may need some experience in Python and object oriented programming.

💻 MicroPython: An Intro to Programming Hardware in Python

Are you interested in the Internet of Things, home automation, and connected devices? Have you ever wondered what it would be like to build a blaster, a laser sword, or even your own robot? If so, then you’re in luck! MicroPython can help you do all of those things and more.

In this tutorial, you’ll learn about:
▫️ The history of MicroPython
▫️ The differences between MicroPython and other programming languages
▫️ The hardware you’ll use to build devices
▫️ The process to set up, code, and deploy your own MicroPython project

🧠 Popular ML algorithms (MATLAB, Octave, Python)

A perfect compilation of code examples of the most popular ML algorithms for understanding its work.

The purpose of these repositories was not to implement machine learning algorithms using 3rd party libraries "one-liners" but rather to practice and to better understand the mathematics behind each algorithm.

🧠 Neural Network From Scratch

Neural nets are increasingly dominating the field of machine learning / artificial intelligence: the most sophisticated models for computer vision, natural language processing, translation, and more are based on neural nets.

How do they work? Why are they so good? Why are they so slow? Why are GPUs/TPUs used to speed them up? Why do the biggest models have more neurons than humans, yet still perform worse than the human brain?

The best course of action to answer those questions is by implementing a simple neural net from scratch.

📃 Top 5 MicroPython IDEs for ESP32 and ESP8266

IDEs compatible with MicroPython that you can use to program your ESP boards. You should choose the IDE that best suits your needs:

▫️ Mu Editor is a simple Python editor for beginner programmers. It works pretty well, comes with a simple and intuitive interface, and provides a menu to burn MicroPython firmware to your boards quickly, so you don’t need to use esptool to burn firmware.

▫️ uPyCraft IDE was specifically designed to be used with MicroPython. With this IDE it is pretty easy to establish communication with the board once you select the right COM port.

▫️ Thonny IDE is a simple IDE for Python with MicroPython support. Intuitive, simple, and easy to use.

▫️ VS Code + Pymakr Extension is an excellent choice for those who are used to VS Code.

▫️ PyCharm is an advanced Python IDE with cool features like code completion, debugging, error highlights, and it helps you write better Python code by providing tips and tricks.

📟 ESP32/ESP8266: MicroPython OTA Updates via PHP Server

OTA (Over-the-Air) update is the process of loading new firmware to the ESP32 or ESP8266 board using a Wi-Fi connection rather than a serial communication. This functionality is extremely useful in case of no physical access to the board.

In this project, we’ll show you an example of how you can do OTA updates to your ESP32/ESP8266 boards running MicroPython code via a PHP server.

In summary, you’ll create a PHP server in which you can submit a new code that you want to run on the ESP. When there is a new code/update available, the ESP downloads the new code, reboots, and starts running the newly downloaded code.

💻 PikaScript – ultra-lightweight Python engine

PikaScript is an ultra-lightweight Python engine that can run on microcontrollers with as little as 4KB of RAM and 32KB of Flash, while the more popular MicroPython requires at least 256kB of code space and 16kB of RAM.

PikaScript was initially developed to run on STM32G030C8 and STM32F103C8 MCUs, meaning, for example, it works on the BluePill board, but it has also been ported to other platforms like WCH CH582 RISC-V MCU, WinnerMicro W806 C-Sky microcontroller.

PikaScript also permits the binding C function to a Python module through Pika Pre-compiler. PikaScript can run bare metal on the microcontroller, but also supports real-time operating systems such as RT-Thread and VSF (Versaloon Software Framework), as well as Linux.

💻 MIT Turbocharges Python’s Notoriously Slow Compiler

Python has long been one of—if not the—top programming languages in use. Yet while the high-level language’s simplified syntax makes it easy to learn and use, it can be slower compared to lower-level languages such as C or C++.

Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) hope to change that through Codon, a Python-based compiler that allows users to write Python code that runs as efficiently as a program in C or C++.

In terms of what’s next for Codon, researchers are currently working on native implementations of widely used Python libraries, as well as library-specific optimizations to get much better performance out of these libraries.
