Light Control (LED)

---

1. Overview

The led in the component package is a light control component, which provides the following common scene light control codes.

• Color lamp: RGB lamp or RGB W lamp, using PWM control and HSV color gamut space, with rich colors and good brightness effect, can adjust the color and brightness separately without affecting each other;

• Nightlight: PWM control, adjustable brightness;

• Blinking light: use ordinary IO and software timer control, one for reference in toys, and one simple IO to achieve wake-up response effect.

2. Instructions

Function interface	Description
color_light_init	Initialize lamp control components
color_light_control	Set Color (HSV all)
color_light_set_level	Set Color (hue and saturation)
color_light_set_color	Set brightness (value(lightness))
night_light_init	Light initialization
night_light_set_brightness	Setting brightness of light
blink_light_init	Blink initialization
blink_light_on	Blink light is turned on once

Example:

#define POWER_ON_COLOR 360,1.0,1.0 //179,0.32,0.3

/*Color lamp example*/
void light_init(void)
{
/*Initialize lamp control components*/
color_light_init();
/*Set Color*/
color_light_control(POWER_ON_COLOR);
color_light_set_level(0.0);

ci_loginfo(LOG_USER,"color light ok\n");

for(int i=0;i<100;i++)
{
color_light_set_level((float)i/100.0);
vTaskDelay(pdMS_TO_TICKS(50));
}
}

/*Example of night light*/
void light_sample(void)
{
/*Initialize*/
night_light_init();
/*Turn on the light and set the brightness to 80%*/
night_light_set_brightness(1,80);
/*Turn off the light*/
night_light_set_brightness(0,80);
}

/*Example of flashing lights*/
void light_sample(void)
{
/*Initialize*/
blink_light_init();
/*Blink once*/
blink_light_on();
}
