[Open Source]DWIN Screen Control WS2812 Ambient Lighting

--From DWIN Developer Forum

This issue for you to push the award-winning open source case of DWIN Developer Forum - DWIN screen control WS2812 ambient lighting, engineers through the COF intelligent screen OS core to accurately control the WS2812 phantom light belt each lamp bead color, to achieve color switching of the belt's dynamic effects.

The driver code for controlling the color of the light through the IO port is as follows:

void WS2812_Write_RGB()

{

u8 i,j,a;

EA=0;

for(j=0;j<3;j++)//Number of transmissions required for each light

{

a=RGB_One[j];

for(i=0;i<8;i++)

{

WS2812_DI=1;

_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();

WS2812_DI=(a&0x80);

_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();_nop_();

a<<=1;

WS2812_DI=0;

}

WS2812_DI=0;

}

EA=1;

}

void WS2812_RST()

{

WS2812_DI=0;

sys_delay_ms(1);

}

void WS2812_DIS_1()//Effect 1, color switching, all LED colors, a total of 7 basic colors

{

static u8 j=1;

u16 i=0;

if(j&0X01) RGB_One[1]=10;else RGB_One[1]=0;

if(j&0X02) RGB_One[0]=10;else RGB_One[0]=0;

if(j&0X04) RGB_One[2]=10;else RGB_One[2]=0;

j%=7;

j++;

for(i=0;i<num_val;i++)

WS2812_Write_RGB();

WS2812_RST();

sys_delay_ms(1000);

}
