Tourist Info Display

​Hardware components used:
* ESP32 (Lolin32) with 4BM Flash memory
* Tourist Information: 0.96" 80x160 RGB IPS display with ST7735 driver (only the top 80x80 pixels are used and visible)
  
  Connections:
  DISPLAY      ESP32
  --------------------
  GND            GND
  VCC             V3
  SCL             SCL       (SPI Clock)
  SDA            MOSI     (SPI Data (to slave))
  RES            GPIO4    (Reset)
  DC              GPIO2    (Data/Command)
  CS              SS/5      (Chip Select)
  BLK            GPIO15

Uploading files to the ESP32 flash:
Install ESP32 Filesystem Uploader in Arduino IDE
https://randomnerdtutorials.com/install-esp32-filesystem-uploader-arduino-ide/
https://github.com/me-no-dev/arduino-esp32fs-plugin/releases/

The size of the ESP32 SPIFFS partition can be set in the IDE as 1Mbyte or 3Mbytes.

Place the video/image files inside the sketch folder, in a folder called "Data".  Then upload all the files in the folder using the Arduino IDE "ESP32 Sketch Data Upload" option in the "Tools" menu.
​
The sketch loads
- an 80x80 pixel background image (back.jpeg) once at the beginning
- a sequence of up to one thousand 40x80 images (videoNNN.jpeg) stored in the built-in flash memory.
  
The videoNNN.jpeg files are built as follows:
- Scale and crop the source video to 40x80 (portrait) with Handbrake
- Extract the .jpeg files with ffmpeg:
    ./ffmpeg -i video.mp4 -s 40x80 -r 10 video%03d.jpeg
