Atom Display

SKU:K115

Description

ATOM Display is a cost-effective display driver that uses an FPGA to emulate traditional SPI TFT-LCD data output, supporting up to 720P (1280x720) image output. It achieves broad compatibility for display output through a dedicated RGB-to-high-definition multimedia signal chip. Built with an embedded ESP32 controller, it integrates 2.4G Wi-Fi and an 8M Flash + 2M PSRAM memory combination. ATOM Display can replace traditional PC-controlled display panel solutions, offering a more cost-effective alternative.

Note

ATOM Display requires a display with adaptive resolution scaling. Some displays without this feature may experience display abnormalities.

Example Program

Arduino

M5GFX - Lib

Programming Note

Before using the example programs in the M5GFX library, ensure the included header files are adjusted for the current device in use. For instance, include #include <M5AtomDisplay.h> and create an instance M5AtomDisplay display; as shown below.

#include <Arduino.h>
#include <vector>

#include <M5AtomDisplay.h>
M5AtomDisplay display;

void setup(void)
{
  display.begin();
}

void loop(void)
{
  display.fillScreen(RED);
  delay(1000);
  display.fillScreen(GREEN);
  delay(1000);
  display.fillScreen(BLUE);
  delay(1000);
}
