Hello @cepics
SmallHD 503 : 1920 x 1080
:--------------------------------------------------
Arduino IDE
#include <M5AtomDisplay.h>
You can set the resolution (width, height) with the argument.
If omitted, 1280, 720
// M5AtomDisplay display(); // 1280 x 720
M5AtomDisplay display(1920,1080,24); // 1920 x 1080 , 24bit
// TOSHIBA REGZA 32BC3 32inch 1366x768
// M5AtomDisplay display(1366,768); // 1366 x 768
// M5AtomDisplay display(1920/2,1080/2,24);
example
// ( 480, 1920);(1920, 480);(1280, 720);(1024, 768);
// ( 960, 540);( 800, 600);( 640, 480);( 640, 400);
// ( 640, 360);( 512, 212);( 256, 192);( 320, 240);
// ( 240, 320);( 200, 200);( 240, 135);( 135, 240);
// ( 160, 160);( 160, 80);( 80, 160);( 80, 80);
It may not be displayed correctly depending on the supported resolution of the display.
It may be possible to display by setting the resolution (width, height) to be output to the display with arguments 3 and 4.
You can also set the width and height magnification with arguments 5 and 6.
If the enlarged resolution is less than the output resolution, there will be a gap around the screen.
// M5AtomDisplay display ( 512, 384, 1280, 800, 2, 2 );
// M5AtomDisplay display ( 683, 384, 1366, 768, 2, 2 );
- The width magnification must be a number that is divisible by the width of the output resolution
// ex: M5AtomDisplay display ( 400, 250, 1280, 800, 3, 3 );
In this example, 1280 is not divisible by 3, so the horizontal magnification is changed to 2.
