LED Matrix 32*64 LED blinking

by eve7536 on Mon Nov 16, 2020 8:05 am

Hello,
I bought a 32*64 LED matrix 3mm on your website.
I use a 5V/2A power supply and Arduino mega to control it, the code as follows.

The LED will blinking when I see the LED on my sensor, but it will not flicker with human eyes.

I need it to be a stable light source.

Where can I change the frequency or the refresh time in the libraries?
I've tried the "SPI_OBJECT.setClockDivider" and "setClock" in the Adafruit_SPITFT_Macros.
Or can you provide the datasheet(Hardware composition) to me?


Code: Select all | TOGGLE FULL SIZE
#include <RGBmatrixPanel.h>


#define CLK  11   
#define OE   9
#define LAT 10
#define A   A0
#define B   A1
#define C   A2
#define D   A3

int x = 49, y = 16;

RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, false, 64);
void setup() {
  // put your setup code here, to run once:
  matrix.begin();

  matrix.drawPixel(x, y, matrix.Color333(7, 7, 7));
}

void loop() {
  // put your main code here, to run repeatedly:

}
