PUSH or SCAN – branch on this, not on the name.

init

bool(* LL_Panel::init) (Lamb &lamb)

bring up bus + controller; idempotent

fill

void(* LL_Panel::fill) (Lamb &lamb, int x, int y, int w, int h, uint16_t color)

filled rect, RGB565

blit

void(* LL_Panel::blit) (Lamb &lamb, int x, int y, int w, int h, const uint16_t *src)

PUSH only; NULL on SCAN.

fb

uint16_t *(* LL_Panel::fb) (void)

SCAN only; NULL on PUSH.

set_brightness

void(* LL_Panel::set_brightness) (Lamb &lamb, int percent)

0..100, or NULL if the panel has none

on_off

void(* LL_Panel::on_off) (Lamb &lamb, bool on)

display on/off, or NULL
