Circular LED Test

Hello
I had a few questions about the CircularLEDtest code.
I’m trying to understand how to control the CircularLED

#include <CircularLED.h>
CircularLED circularLED1(10,9); //What is happening here ?
CircularLED circularLED2(16,15);
//CircularLED circularLED;

unsigned int LED[24];
int k=0;
void setup()

{
Serial.begin(9600);
//circularLED1.init(); What is happening here ?
}
void loop()
{
for (int i =0;i<24;i++)
{
LED[i]=0;
}
LED[k]= 0xff; //what is this ?
k++;
if (k==24)
k=0;

circularLED1.CircularLEDWrite(LED); // what is this and why are there 2 of them ?
circularLED2.CircularLEDWrite(LED);
delay(40);
}

When I upload this sketch I get an error like this. When I move around the LED disk, it just flashes randomly. What is causing this ?

Hello,

CircularLED circularLED1(10,9); //defines D9 and D10 as pwm port
circularLED1.CircularLEDWrite(LED); // To  assign a value to the output port

Two of them are given so that this example can be used for two circular LED in different ports.
You can delete one if you are using only one circular LED.

Thanks and Regards
