Downloading Bitmap via WiFi with CircuitPython, Saving to Local File System, and Displaying on LCD using OnDiskBitmap.

In my previous post , I demonstrated basic exercises running on the Raspberry Pi Pico 2 W with CircuitPython 10.0.3, displaying graphics on a 1.28‑inch IPS module (GC9A01 + CST816S, 240×240 round, 4‑wire SPI) . In this post, I present exercises using CircuitPython 10.0.3 on the Raspberry Pi Pico 2 W to download a bitmap via WiFi, save it to the local file system, and display it on the GC9A01 LCD using OnDiskBitmap. The BMP in my test was resized and converted from JPG to BMP(240*240 RGB888) using FFmpeg . cpy_rpPicoW_gc9a01_OnDiskBitmap_wifi.py """ Raspberry Pi Pico 2 W/CircuitPython 10.0.3 with 1.28" 240x240 Round GC9A01 SPI IPS LCD Download bmp to local file system and display it using OnDiskBitmap ~ Single bmp. In this exercise, Pico 2 W download image from web server, save it on CircuitPython local filesystem, named "image.bmp, then display it on 1.28" 240x240 Round GC9A01 SPI IPS LCD using OnDiskBitmap. https://coxxect.blogspot.com/2026/01/downloa...

Python exercises to auto-play jpg and mp4

Image
The Python code listed below auto-play jpg and mp4 in "files" sub-folder, run on Windows 11.  Remark: These Python programs require OpenCV and ffpyplayer. Since I encountered some issues installing OpenCV on the latest Python 3.14, I created a Python 3.12 virtual environment to install OpenCV and ffpyplayer. Related:  Create Python virtual environment in Windows 11 play_jpg.py """ Python to auto play all jpg in "files" sub-folder.
