  • Show a message (Unicode supported)
ledMatrix.ShowMessage(string message, Color? foreColor = null, Color? backColor = null, Rotation textRotation = Rotation.Rotate0, Direction scrollDirection = Direction.Left, int speedInMs = 90)
  • Show a series of values (Unicode supported)
ledMatrix.ShowSeriesValues(float[] values, Color? foreColor = null, Color? backColor = null, bool fill = false, Rotation rotation = Rotation.Rotate0, bool forward = true, int speedInMs = 90)

Unicode 8 x 8 Font

Built-in unicode characters

  • U+0000 - U+007F (basic latin)
  • U+00A0 - U+00FF (extended latin)

Add custom characters

See section Encoding for glyph.

Font8x8.AddGlyph(char letter, byte[] glyph)

Encoding

Every character in the font is encoded row-wise in 8 bytes.

The most significant bit of each byte corresponds to the first pixel in a row.

The character 'A' (0x41 / 65) is encoded as { 0x30, 0x78, 0xCC, 0xCC, 0xFC, 0xCC, 0xCC, 0x00 }

0x30 => 0011 0000 => ..XX....
0x78 => 0111 1000 => .XXXX...
0xCC => 1100 1100 => XX..XX..
0xCC => 1100 1100 => XX..XX..
0xFC => 1111 1100 => XXXXXX..
0xCC => 1100 1100 => XX..XX..
0xCC => 1100 1100 => XX..XX..
0x00 => 0000 0000 => ........

To access the nth pixel in a row, right-shift by 7-n.

                     . . X X . . . .
