ATOM Display

SKU:K115

Description

ATOM Display is an all-in-one display driver kit, Use FPGA to simulate traditional SPI TFT-LCD Data output. This kit supports image at a maximum resolution of 1280 x 720 pixels. It provides advanced signal with great precision colors. Integrated 2.4G Wi-Fi, with 8M Flash + 2M PSRAM memory combination, RGB TO HDMI convert chip. So small yet powerful, which can replace the traditional display driving solution.

Note: ATOM Display needs to be paired with monitors with adaptive resolution scaling.

Schematic

Example

Arduino

Before using the case program in the M5GFX library, you need to change the imported header file to adapt to the currently used device. Introduce #include <M5AtomDisplay.h> as shown in the following program example, and create an instance M5AtomDisplay display;

#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);
}
