Member Data Documentation

clear

esp_err_t(* led_strip_t::clear) (led_strip_t *strip)

Clear LED strip (turn off all LEDs)

Parameters

strip	LED strip
timeout_ms	timeout value for clearing task

Returns

• ESP_OK: Clear LEDs successfully
• ESP_FAIL: Clear LEDs failed because some other error occurred

Definition at line 83 of file led_strip_interface.h.

del

esp_err_t(* led_strip_t::del) (led_strip_t *strip)

Free LED strip resources.

Parameters

strip

LED strip

Returns

• ESP_OK: Free resources successfully
• ESP_FAIL: Free resources failed because error occurred

Definition at line 94 of file led_strip_interface.h.

refresh

esp_err_t(* led_strip_t::refresh) (led_strip_t *strip)

Refresh memory colors to LEDs.

Parameters

strip	LED strip
timeout_ms	timeout value for refreshing task

Returns

• ESP_OK: Refresh successfully
• ESP_FAIL: Refresh failed because some other error occurred

Note

: After updating the LED colors in the memory, a following invocation of this API is needed to flush colors to strip.

Definition at line 67 of file led_strip_interface.h.

refresh_async

esp_err_t(* led_strip_t::refresh_async) (led_strip_t *strip)

Definition at line 70 of file led_strip_interface.h.

refresh_wait_done

esp_err_t(* led_strip_t::refresh_wait_done) (led_strip_t *strip)

Definition at line 71 of file led_strip_interface.h.

set_pixel

esp_err_t(* led_strip_t::set_pixel) (led_strip_t *strip, uint32_t index, uint32_t red, uint32_t green, uint32_t blue)

Set RGB for a specific pixel.

Parameters

strip	LED strip
index	index of pixel to set
red	red part of color
green	green part of color
blue	blue part of color

Returns

• ESP_OK: Set RGB for a specific pixel successfully
• ESP_ERR_INVALID_ARG: Set RGB for a specific pixel failed because of invalid parameters
• ESP_FAIL: Set RGB for a specific pixel failed because other error occurred

Definition at line 35 of file led_strip_interface.h.

set_pixel_rgbw

esp_err_t(* led_strip_t::set_pixel_rgbw) (led_strip_t *strip, uint32_t index, uint32_t red, uint32_t green, uint32_t blue, uint32_t white)

Set RGBW for a specific pixel.

Similar to set_pixel but also set the white component

Parameters

strip	LED strip
index	index of pixel to set
red	red part of color
green	green part of color
blue	blue part of color
white	separate white component

Returns

• ESP_OK: Set RGBW color for a specific pixel successfully
• ESP_ERR_INVALID_ARG: Set RGBW color for a specific pixel failed because of an invalid argument
• ESP_FAIL: Set RGBW color for a specific pixel failed because other error occurred
