Struct ColumnAddressSet 

pub struct ColumnAddressSet { /* private fields */ }

CASET (§8.1.14): column window for the following RAMWR, inclusive.

One column is 3 bytes of GRAM. The field is 6 bits (0..=63). The usable range depends on the panel wiring: datasheet v0.2 gives 0x13..=0x28 for a 264-source layout, the Waveshare 4.2“ panel uses 0x12..=0x2A.

Implementations

impl ColumnAddressSet

pub const DEFAULT: Self

Register default 0x00, 0x00: column 0 only.

pub const fn new(xs: u8, xe: u8) -> Self

Columns xs..=xe.

Panics

If xs > xe or xe > 63 (at compile time in a const).
