Add an empty column between characters of scrolling text so that the individual characters are more easily distinguishable instead of being back-to-back mashed together. Also adjust the default scrolling step interval so that the character display frequency stays roughly the same as before.

help
|
|
By default, the micro:bit display driver will update the GPIO
|
|
pins of the display (pins 4 through 15) by accessing the entire
|
|
GPIO port. This is done for efficiency, however it may interfere
|
|
with other peripherals connected to the same GPIO port. Select
|
|
this option if other peripherals are connected to the same GPIO
|
|
port.

help
|
|
This value specifies the time between two scrolling steps of the
|
|
string scrolling functionality. Smaller values mean faster
|
|
scrolling whereas bigger values mean slower scrolling. It is
|
|
usually best to leave this at its default value (80ms).
