The software for the animated gif frame, consist of 3 parts.<\/p>\n

    \n
  1. code for the Arduino, that reads the sd-card and displays it on\u00a0the ledstrips (main board)<\/em><\/li>\n
  2. code for the Arduino, that runs the LCD menu (menu)<\/em><\/li>\n
  3. code on the PC, which converts a GIF\u00a0into a text file, with the color codes of the GIF.<\/li>\n<\/ol>\n

    Arduino sketch<\/h2>\n

    The two Arduinos communicates via the serial ports.
    \nAt startup the main board, request the menu for the current settings. (it does this\u00a0by sending a request_signal<\/em>)<\/p>\n

    Serial.write(REQUEST_DATA);       \/\/ request for new data    - value is 155\r\n<\/pre>\n
    The menu, then sends the settings in the following format<\/p>\n
    Serial.write(START_SIGNAL);       \/\/ 111\r\nSerial.write(loadNext ? 1 : 0);   \/\/ next                    - values 0 or 1\r\nSerial.write(menu.mode);          \/\/ mode (single\/slideshow) - values 0 or 1\r\nSerial.write(menu.repeat);        \/\/ slideshow duration      - values 1 to 50\r\nSerial.write(menu.speed);         \/\/ speed                   - values 10 to 100\r\nSerial.write(menu.brightness);    \/\/ brightness              - values 10 to 60\r\nSerial.write(END_SIGNAL);         \/\/ 222\r\n<\/pre>\n
    Whenever a change in the menu happens, it will also send this byte array to the main board.
    \nThe menu also,saves the changes to EPROM, so that the settings\u00a0can be restored when power off and on.<\/p>\n

    PC software<\/h2>\n
    On the PC side, I used this Processing sketch, but I think i\u00a0really\u00a0is just Java. Kinda like Arduino sketch is C\/C++.
    \n    https:\/\/github.com\/MeULEDs\/MeU_Square_GIF_Converter_Teensy<\/a><\/p>\n
    I modified the original code, so I only outputs the color codes, and not the Arduino sketch code.
