ATOM Display Lite

SKU:K115-B

Description

ATOM Display Lite is an all-in-one display driver kit. Use FPGA to simulate traditional SPI TFT-LCD Data output. This kit supports images at a maximum resolution of 1280 x 720 pixels (720P). Built-in LT8618SX RGB to HDMI chip supports wide range HDMI signal output. Integrate 2.4G Wi-Fi, with 4M Flash + 520KB SRAM. So small yet powerful, which can replace the traditional display driving solution.

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

Before using the examples in the M5GFX library, you need to change the header file to match the device you are currently using. Introduce #include <M5AtomDisplay.h> and create the example M5AtomDisplay display; as shown in the example 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);
}
