	Turn the panel on.
int(*	disable )(const struct pbl_display *disp)
	Turn the panel off.
int(*	set_rotated )(const struct pbl_display *disp, bool rotated)
	Turn the image by 180 degrees, mounting rotation included, from the next update.
int(*	update )(const struct pbl_display *disp, const struct pbl_display_buffer *buf, uint16_t y0, uint16_t y1)

int(*	clear )(const struct pbl_display *disp)
	Clear the image held by the panel.

Detailed Description

Display driver operations.

The class layer owns the update state and the rotation request; drivers move rows to the panel and report the end of an update with pbl_display_complete().

Turn the panel off.

Returns 0 or a negative errno.

enable

int(* pbl_display_ops::enable) (const struct pbl_display *disp)

Turn the panel on.

Returns 0 or a negative errno.

init

Set the display up, with the panel on.

Returns 0 or a negative errno.

set_rotated

int(* pbl_display_ops::set_rotated) (const struct pbl_display *disp, bool rotated)

Turn the image by 180 degrees, mounting rotation included, from the next update.

Returns 0 or a negative errno.

update

int(* pbl_display_ops::update) (const struct pbl_display *disp, const struct pbl_display_buffer *buf, uint16_t y0, uint16_t y1)
