Hello all,

Do any of you golden hearted coders know of any library to handle LED strips, namely the TM1809 chip?

Any help will be truly appreciated.

Code:

    red = (led_strip_colors[i] >> 16) & 0xFF;
    spi_write(red);
    spi_write(green);
    spi_write(blue);
  }
  delay_us(500);    // delay 500us to latch the IC
}


void main()

while(true){



    for(i = 0 ; i < LED_STRIP_LEN ; i++) {led_strip_colors[i] = 0;}

    led_strip_colors[0] = 0xFF0000;  // red
    led_strip_colors[1] = 0x00FF00;  // green
    led_strip_colors[2] = 0x0000FF;  // blue
    led_strip_colors[3] = 0x00FFFF;  // green + blue

    led_strip_colors[7] = 0xFFFFFF;  // red + green + blue (white)

    send_frame();

    delay_ms(500);

lcd_gotoxy(2,2);
printf(lcd_putc,"%lu pass",x);
x=x+1;


}// forever while loop   
}// end of main
