Set Grove - RGB LED Matrix w/Driver to show white light all the time

I am using the Grove - RGB LED Matrix w/Driver, How can I set it to show white light all the time without flashing?

Script:

#include “grove_two_rgb_led_matrix.h”

#ifdef ARDUINO_SAMD_VARIANT_COMPLIANCE
#define SERIAL SerialUSB
#else
#define SERIAL Serial
#endif

uint64_t example[] = {
//all white
0xfefefefefefefefe,
0xfefefefefefefefe,
0xfefefefefefefefe,
0xfefefefefefefefe,
0xfefefefefefefefe,
0xfefefefefefefefe,

0xfefefefefefefefe,
};

void waitForMatrixReady()
{
delay(1000);
}

GroveTwoRGBLedMatrixClass matrix;
void setup()
{
Wire.begin();
SERIAL.begin(115200);
waitForMatrixReady();
uint16_t VID = 0;
VID = matrix.getDeviceVID();
if(VID != 0x2886)
{
SERIAL.println(“Can not detect led matrix!!!”);
while(1);
}
SERIAL.println(“Matrix init success!!!”);

}

void loop()
{

for (int i=0;i<3;i++) {
matrix.displayFrames(example+i*8, 200, false, 1);
delay(1000);
}
}

#2

remove delay(1000); . It should not flash.

#3

When I remove the delay(1000); below the matrix.displayFrames(example+i*8, 200, false, 1) it is flickering in high frequency. Any idea?

#4

Do you use Arduino UNO?These are microprocessors that run too low.That’s true. You can test Arduino with higher speed.

#5

I use seeeduino and base shield

#6

it is really slow. You can try a more advanced board.

#7

Is there another way to just let it show white light without flashing?

#8

Try this and see if it works
