OLED Guides, Tutorials & Diagnostics
Practical, hardware-tested guides for displaying graphics and animations on SSD1306, SH1106, SH1107, and SSD1327 OLED screens with Arduino, ESP32, and RP2040.
OLED Troubleshooting: Scrambled, Mirrored, Shifted or Blank Displays
Diagnostic symptom-cause-fix table covering MSB vs LSB bit order, SH1106 2-pixel column shift, I2C address detection, and Arduino Uno RAM exhaustion fixes.
How to Display an Image on an SSD1306 OLED with Arduino
Complete wiring schematic (A4/A5, 0x3C), library installation, byte conversion workflow, and a ready-to-upload Arduino sketch combining graphics with text.
image2cpp Alternative, Compared Honestly
Side-by-side feature comparison between image2cpp and OLED Bitmap Converter: GIF animation timing, vector flash compression, U8g2 XBM handling, and when to use each tool.
Smaller Than a Bitmap: Vector Code Shrinks OLED Flash
Measured memory benchmarks: how converting outlines, logos, and badges into fillRect and drawLine primitives saves 40% to 70% of Arduino PROGMEM compared to raw 1,024-byte bitmaps.
