UncannyEyesESP32

This is a ESP32 compatible redo of Adafruit https://github.com/adafruit/Uncanny_Eyes for ESP32 using default Adafruit_GFX library. For halloween decorations, raves, etc

Components used

• 2 x 128x128 RGB565 16-bit SSD1351 OLED display
• 1 x ESP32 38 pin dev board
• [Optional] Use some kind of plano convex lens in front of this to make it more like an eye than a display.

Connections

ESP32 has 2 SPI buses called VSPI and HSPI. Connect the 2 displays to them. (DIN on display <-> MOSI on ESP32, others should be self explanatory)

	DIN	CLK	CS	DC	RST
Left Display	13	14	27	26	25
Right Display	23	18	0	17	16

Compiling software

• Get arduino IDE
• Install the following libraries
  • Adafruit-GFX-Library
  • Adafruit-SSD1351-library
• Open AppaEyes.ino , compile and upload to your ESP32

Notes

• I was able to drive the display at SPI_FREQUENCY 30000000 and gave consistent 30FPS driving 2 displays with 1 ESP32 or at 60 FPS for 1 display on 1 ESP32 (you can also try assiging 1 core each to the displays on dual core ESP32 for higher performance) . Try lowering this frequency if the display looks corrupted
• You can change the asset data.h to any RGB565 image. Just make sure you maintain the dimentions of the image. Refer data.h on tools to convert
