Struct microbit_text::scrolling_text::ScrollingBufferedText

pub struct ScrollingBufferedText<const N: usize> { /* fields omitted */ }

A Scrollable displaying an ascii byte-string of up to N bytes.

Implementations

impl<const N: usize> ScrollingBufferedText<N>

pub fn set_message(&mut self, message: &[u8])

Specifies the ascii byte-string to be displayed.

Makes a copy of the byte-string.

This also resets the animation to the beginning.

Panics

Panics if message is more than N bytes long.
