VirtualBox how to: automatically capture USB devices for use in a virtual machine

A USB filter in VirtualBox allows you to automatically capture USB devices for use in a virtual machine (VM). This ensures that the device is passed directly to the guest OS when connected, bypassing the host system. Steps to Add a USB Filter 1. Install VirtualBox Extension Pack      Ensure the Extension Pack is installed on the host. It adds support for USB 2.0/3.0. Download and install it from the VirtualBox website . 2. Enable USB Controller in VM Settings      Open VirtualBox and select your VM. Go to Settings > USB. Enable USB 2.0 (EHCI) or USB 3.0 (xHCI) depending on your guest OS support. 3. Create a USB Filter      While the USB device is connected to the host, click Add Filter (+) in the USB settings of your VM. A new filter will be created with details like Vendor ID, Product ID, etc., pre-filled for the connected device. You can edit these fields if needed (e.g., leave fields blank for broader matching). 4. Start the VM and Conn...

Downloading and Displaying JPG Images via WiFi on ESP32-C5 with ST7789 SPI TFT LCD

Image
In this exercise, I demonstrate how to download a JPG image over Wi-Fi, decode it using the JPEGDEC library, and display it on a 3.2-inch 240×320 ST7789 TFT LCD (4-wire SPI) . The project uses the Arduino_GFX_Library together with the Waveshare ESP32-C5-WIFI6-KIT-N16R8 , running in the Arduino framework.

ESP32-xx to use 16MB Flash with LittleFS.

Image
In my understanding: To use 16MB Flash with LittleFS, have to select Partition Scheme of 16M Flash (2MB APP/12.5MB FATFS) or 16M Flash (3MB APP/9.9MB FATFS). Tested on  Waveshare ESP32-C5-WIFI6-KIT-N16R8 . ESP32-xx_LittleLS_16M.ino /* Exercise on ESP32-xx to use 16MB Flash with LittleFS.
