The purpose of this exercise is to test the behavior of MicroPython _thread, specifically for Raspberry Pi Pico series, whether _thread.start_new_thread() can provide real multi-core parallel speedup for pure Python CPU-bound work.  mpy_thread_smp_bench.py # mpy_thread_smp_bench.py # # Purpose: # Simple MicroPython benchmark to test whether _thread.start_new_thread() # can provide real multi-core parallel speedup for pure Python CPU-bound work. # # Method: # 1. Run a CPU-bound loop in the main thread and measure the duration. # This is the single-thread baseline. # # 2. Run the same CPU-bound loop in two threads: # - one in the main thread # - one in a newly created _thread # # 3. Measure: # - duration of thread 0 # - duration of thread 1 # - total wall-clock time from starting both threads until both finish # # Interpretation: # Let single-thread duration be T. # # If the two CPU jobs run fully in parallel on two cores: # ...

In this post, we build a small desktop slideshow application with Python and PyQt6. The app lets you pick any folder through a built-in file explorer, then plays its contents as a slideshow — each image is displayed for 5 seconds, each video plays once, and a mouse click or touch tap skips to the next item. The walkthrough covers the full real-world workflow on Windows: create an isolated virtual environment, install PyQt6, run the app from source, and finally package everything into a single standalone .exe with PyInstaller — so the finished slideshow can run on any Windows PC, even one without Python installed. To create a Python virtual environment , enter in Command Prompt: python -m venv .venv Creates an isolated Python environment in a .venv folder, keeping this project's dependencies separate from the system-wide Python. (.venv is just a naming convention — any folder name works.) To activate it, enter: .venv\Scripts\activate.bat or .venv\Scri...

In this post, we will look at how to interface and display data on a 0.96-inch 128x64 SSD1315 I2C OLED display using ESP32-C5_MINI and MicroPython. For these exercises, we will use the official micropython-ssd1306 driver. Because the SSD1315 shares the exact same command structure for basic operations as the classic SSD1306, this library works flawlessly out of the box. Getting the Library There are two easy ways to install the driver on your board: Via Thonny IDE: Go to Tools ➔ Manage packages..., search for micropython-ssd1306, and click Install. Manual Installation: Download ssd1306.py directly from the official MicroPython-lib repository and save it onto your ESP32-C5 file system. Connection SDA - IO3 SCL - IO4 VCC - 3V3 GND - GND Exercise Code mpy_C5_ssd1306.py , basic setup and test.

This post walks you through the step-by-step process of flashing MicroPython firmware onto the ESP32-C5_MINI . 1. Download the MicroPython Firmware First, grab the correct binary for your chip: Visit the official MicroPython Download Page . Search or scroll down to the ESP32 section and locate the ESP32-C5 targets. Select ESP32-C5 by Espressif and download your preferred .bin file version. 2. Flash the Firmware (The 0x2000 Offset) To flash the firmware, connect your board to your computer and run the following esptool command. ⚠️ Crucial Note: Unlike older ESP32 chips (like the S3) which often start flashing at 0x0 , the ESP32-C5 requires you to write the flash starting exactly at address 0x2000 . Run this command in your terminal (replace PORTNAME and the .bin filename with your actual values): esptool --port PORTNAME ...
