|
Extra delay before reset/init, in milliseconds. Useful when the panel's power rail is
|
|
gated by a gpio-hog node: devicetree devices (including gpio-hog) are constructed and
|
|
started during kernel_init(), with no built-in settle time between one device starting
|
|
and the next, so a panel whose power was only just enabled a moment earlier may need this
|
|
to let its rail stabilize before communication starts. 0 (the default) adds no delay.
|

init-sequence:
|
|
type: array
|
|
element-type: uint8_t

description: >
|
|
Custom vendor bring-up sequence: a flat list of command bytes, each sent as its own
|
|
single-byte SSD1306 command (some standalone, some acting as a parameter to the byte
|
|
before them - this chip's protocol doesn't distinguish the two at the wire level, and
|
|
neither does this encoding). Omit to use the SSD1306 component's own generic
|
|
esp_lcd_panel_init() sequence instead - note that some panels are known not to
|
|
initialize correctly through it (see e.g. the Heltec WiFi LoRa 32 V3's own required
|
|
override), so most boards should supply their own sequence here.
|
|
|
|
# No 'backlight' property: SSD1306 is a self-emitting OLED panel with no backlight to control,
|
|
# unlike this repo's other display bindings.
