Member Function Documentation

◆ brightness_update()

static void lampda::modes::BasicMode::brightness_update	(	auto &	ctx,
		brightness_t	brightness
	)

inlinestaticinherited

Custom callback when brightness changes (optional)

Callback active only if BasicMode::hasBrightCallback is True

Parameters

[in]	ctx	The current context
[in]	brightness	The brightness value set by the system

Remarks: Use update_brightness() to change brightness in order for this callback to be correctly handled at runtime

◆ custom_click()

static bool lampda::modes::BasicMode::custom_click	(	auto &	ctx,
		uint8_t	nbClick
	)

inlinestaticinherited

Custom "usermode" button UI for "click" action (optional)

Callback active only if BasicMode::hasButtonCustomUI is True

Parameters

[in]	ctx	The current context
[in]	nbClick	The number of clicks made by the user

Returns: Returns True if default UI action should be prevented

◆ custom_hold()

static bool lampda::modes::BasicMode::custom_hold	(	auto &	ctx,
		uint8_t	nbClickAndHold,
		bool	isEndOfHoldEvent,
		uint32_t	holdDuration
	)

inlinestaticinherited

Custom "usermode" button UI for "click+hold" action (optional)

Callback active only if BasicMode::hasButtonCustomUI is True

Parameters

[in]	ctx	The current context
[in]	nbClickAndHold	The number of clicks made by the user
[in]	isEndOfHoldEvent	True if the user just released the button
[in]	holdDuration	The duration of the on-going hold event

Returns: Returns True if default action must be prevented

Remarks: When isEndOfHoldEvent is True, then holdDuration is zero

◆ get_next_speed()

static int16_t lampda::modes::default_modes::PerlinNoiseMode::get_next_speed	(	auto &	ctx,
		const uint32_t	position,
		int16_t	speed
	)

inlinestatic

compute the next speed from the current parameters. This function prevent overflow by controling the speed between two bounds.

Parameters

[in]	ctx	Contrext object of the mode
[in]	position	Actual position of the noise
[in]	speed	Actual speed of the noise

Returns: The nex speed

◆ on_exit_mode()

static void lampda::modes::BasicMode::on_exit_mode ( auto & ctx )

inlinestaticinherited

Custom callback when mode goes outside of focus (optional)

Parameters

[in] ctx The current context

◆ power_off_sequence()

static void lampda::modes::BasicMode::power_off_sequence ( auto & ctx )

inlinestaticinherited

Custom callback when the system powers off (optional)

Callback active only if BasicMode::hasSystemCallbacks is True

Parameters

[in] ctx The current context

Remarks: This must be a non-blocking function

◆ power_on_sequence()

static void lampda::modes::BasicMode::power_on_sequence ( auto & ctx )

inlinestaticinherited

Custom callback when the system powers on (optional)

Callback active only if BasicMode::hasSystemCallbacks is True

Parameters

[in] ctx The current context

Remarks: This must be a non-blocking function

◆ read_parameters()

static void lampda::modes::BasicMode::read_parameters ( auto & ctx )

inlinestaticinherited

Custom callback to read parameters from filesystem (optional)

Callback active only if BasicMode::hasSystemCallbacks is True

Parameters

[in] ctx The current context

◆ sunset_update()

static void lampda::modes::BasicMode::sunset_update	(	auto &	ctx,
		float	progress
	)

inlinestaticinherited

Custom callback when sunset mode is updated (optional)

Callback active only if BasicMode::hasSunsetAnimation is True

Parameters

[in]	ctx	The current context
[in]	progress	Between 0 and 1, progress of the sunset. At 1, the system turns off

◆ user_thread()

static void lampda::modes::BasicMode::user_thread ( auto & ctx )

inlinestaticinherited

Custom secondary loop, executed in another thread (optional)

Called only if BasicMode::requireUserThread is True

Parameters

[in] ctx The current context

Remarks: This is executed as prologue of user::user_thread() and hence must complete quickly in order to keep the lamp responsive

◆ write_parameters()

static void lampda::modes::BasicMode::write_parameters ( auto & ctx )

inlinestaticinherited

Custom callback to write parameters to filesystem (optional)

Callback active only if BasicMode::hasSystemCallbacks is True

Parameters

[in] ctx The current context

Member Data Documentation

◆ hasSystemCallbacks

constexpr bool lampda::modes::BasicMode::hasSystemCallbacks = false

staticconstexprinherited

Toggles advanced system callbacks, see list here .

Required to use any of the following:

Remarks: By default, these callbacks are called for all modes (not only the active one) and thus should be kept minimal

◆ requireUserThread

constexpr bool lampda::modes::BasicMode::requireUserThread = false

staticconstexprinherited

Toggles the use of custom BasicMode::user_thread() callback.

Remarks: When this is enabled, default is to call hardware::LampTy's show() in user::user_thread() after the BasicMode::user_thread() callback

◆ storeId

constexpr uint32_t lampda::modes::BasicMode::storeId = 0

staticconstexprinherited

Store identifier for persistent storage (optional)

By default, all modes are reset upon a shutdown, providing no persistence of their state across several on/off cycles. To expose to the user a way to configure your mode in a persistent fashion, you can use:

static void loop(auto& ctx) {
  uint8_t rampValue = ctx.get_active_custom_ramp();
  // ... (use rampValue to pick a color or something) ...
}
 
static constexpr bool hasCustomRamp = true; // required

This value is configurable through user interaction with the button. If you need a persistent value, private to your mode, you can use:

static void loop(auto& ctx) {
  uint8_t indexValue = ctx.get_active_custom_index();
  // ... (use indexValue to change how something works) ...
 
  // at some point, indexValue is modified:
  indexValue += 1;
  ctx.set_active_custom_index(indexValue);
 
  // next time mode is enabled, or saved as favorite, both custom
  // values (rampValue, indexValue) are remembered by default
}
 
static constexpr bool hasCustomRamp = true; // also required

These are the two always-available persistent state that a mode can configure by default. However, for more advanced modes (like games, with a list of high-scores, for example) more flexibility can be required.

If you need such extended storage, see ContextTy::KeyProxy for usage.

If you don't need these capabilities, just ignore this identifier :)
