consist of 5x8 pixels and can be addressed with the index 0-7. To describe

the pixels, the first 5 bits of 8 bytes are used. For example, to make
|
|
a custom character "H", you should transfer the following:
|
|
|
|
* ``character[0] = 0b00010001`` (decimal value 17)
|
|
* ``character[1] = 0b00010001`` (decimal value 17)

* ``character[2] = 0b00010001`` (decimal value 17)
|
|
* ``character[3] = 0b00011111`` (decimal value 31)
|
|
* ``character[4] = 0b00010001`` (decimal value 17)
|
|
* ``character[5] = 0b00010001`` (decimal value 17)
|
|
* ``character[6] = 0b00010001`` (decimal value 17)
|
|
* ``character[7] = 0b00000000`` (decimal value 0)

The characters can later be written with :func:`WriteLine` by using the

characters with the byte representation 8 to 15.

You can play around with the custom characters in Brick Viewer since
|

version 2.0.1.

Custom characters are stored by the LCD in RAM, so they have to be set

after each startup.
