To install the Arduino IDE 2.3.8 on Linux Mint

To install the Arduino IDE 2.3.8 on Linux Mint using the AppImage format, tested on Linux Mint 22.3 Xfce over VirtualBox on Windows 11. Step 1: Download the AppImage - Go to the official Arduino Software page . - Look for Arduino IDE 2.3.8 (or the latest version). - Click on the "Linux AppImage 64 bits" link to download the file. - You can move the downloaded file to other folder you want. Step 2: Grant Execution Permission By default, Linux treats downloaded AppImages as non-executable files for security. You must enable execution rights. Option A: Using the Terminal (Recommended) Open your terminal and navigate to the folder contain the downloaded file: chmod +x arduino-ide_2.3.8_Linux_64bit.AppImage Option B: Using the GUI - Right-click the downloaded .AppImage file. - Select Properties. - Go to the Permissions tab. - Check the box that says "Allow executing file as program". Step 3: Configure Serial Port Permissions (dialout) In Linux, your user account needs...

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.
