• no texts available
• IP address

The hardware will ask for texts. Show the last sent text as 'active' in the editor environment

Create a basic homepage with:

• button to create new text
• some simple explanation text
• link to another page to view the texts

Different colors per letter. Every letter may have a specific color out of 7 options.

1. Blue (0, 0, 255)
2. Green (0, 255, 0)
3. Red (255, 0, 0)
4. Cyan (0, 255, 255)
5. Magenta (255, 0, 255)
6. Yellow (255, 255, 0)
7. White (255, 255, 255)

Requires https://hexdocs.pm/elixir_ale/api-reference.html

Assume every 10 seconds or so. And see #6 for the actual interrupt

Header
Byte 1 - 0xFE (start byte)
Byte 2 - background color (see #14)
Byte 3 - speed (see #24)
Byte 4 - font number (see #11)
Byte 5 - spare (0x00)
Byte 6 - spare (0x00)

Content
Byte 6 - letter 1
Byte 7 - color (see #9)
Byte 8 - letter 2
Byte 9 - color
...

End
Byte x - 0xFF (stop byte)

Bold, cursive, underlined?

For example, when doing something important.

Set GPIO8 (pin 24) to high.

E.g. speed of text

Two bytes:
x = 0xFD
x+1 = 0x00 .. 0xFF
Means that the remaining text will hold for 0 up to 255 seconds.

This replaces a single letter.

• SPI speed
• Amount of LED displays connected together (1-4)
• Interrupt pins?
• On/off times?
  -...

See: https://docs.travis-ci.com/user/languages/python/

Byte 7: 0xFC.
Byte 8: 0x00 .. 0xFF
The text will directly show on the ticker text for 0 up to 255 seconds.

Add extra warning that text should be less than a certain amount of letters.

The background color is set for each text separately. It is not possible to vary the background color per letter. It is sent in the 'header' of the protocol.

1. Blue
2. Green
3. Red
4. Cyan
5. Magenta
6. Yellow
7. White

Byte 3: 0x00 .. 0x0F means the speed of the text. 0x00 is the slowest and 0x0F the fastest.

• controller
• view & template

Listen to GPIO4 (pin 7). When it goes high, send data after 100 milliseconds on SPI.

Only when building tags

• controller

• view (very simple, separate page without any formatting)

• template

• disallow any text formatting in quill editor
