Enum mlx9064x::register::AccessPattern[][src]

#[repr(u8)]
pub enum AccessPattern {
    Chess,
    Interleave,
}
Expand description

The pixel access pattern used by a camera.

In chess board mode, the pixels alternate subpages in both the X and Y axes, resulting in a chess or checker board-like pattern:

0 1 0 1 0 1 0 1
1 0 1 0 1 0 1 0
0 1 0 1 0 1 0 1
1 0 1 0 1 0 1 0

The other access mode interleaves each row, so pixels will alternate subpages only on the Y axis. This is also referred to as “TV” mode in the manufacturer’s datasheet.

0 0 0 0 0 0 0 0
1 1 1 1 1 1 1 1
0 0 0 0 0 0 0 0
1 1 1 1 1 1 1 1

Variants

Chess

Pixels alternate between subpages, resulting in a chess or checker board pattern.

This is the default (and strongly recommended value) for the MLX90640.

The MLX90641 updates the entire frame at once with only the read location being alternated. This means that chess mode has no benefit for the MLX90641, and this library doesn’t support it.

Interleave

Each row of pixels is in the same subpage, with the rows alternating between subpages.

This is the default mode for the MLX90641.
