Function from_ascii_byte

pub const fn from_ascii_byte(byte: u8) -> u8

Converts an ASCII byte to a 7-segment display byte.

Unknown characters are converted to 0 (all segments off).

Note

Rust strings are UTF-8 encoded, so what you see as a single character may be multiple bytes.

Example

Display Err text on a 4-digit display:

use tm1637_embedded_hal::{mappings::from_ascii_byte, mock::Noop, TM1637Builder};

let mut tm = TM1637Builder::new(Noop, Noop, Noop).build_blocking::<4>();

tm.init().ok();

let err = "Err".as_bytes().iter().copied().map(from_ascii_byte);

tm.display(0, err).ok();
