@lwtsde said in M5Paper STL Files available?:

M5Paper

Hello!

It depends on the accuracy of the 3D Printer.
M5 Paper requires high accuracy.
You need a high-precision printer.
The accuracy of the printer for amateurs is about 0.4mm width.
I think it is impossible because the accuracy is low.

Hello @Dieter_P

I don't own ATOM Lite (ESP32-PICO-D4), so I haven't checked it.

1. Does the problem occur when using WiFi?
2. You need to check the signal of GPIO39.
   ：

In M5Stack (ESP32-D0WDQ6-V3), there is a case where GPIO39 works without permission when using WiFi.
M5.BtnA.wasPressed() conflicts with WiFi
https://forum.m5stack.com/topic/3262/m5-btna-waspressed-conflicts-with-wifi
：

Supplement：
Example of using GPIO39.
M5Stack Basic (ESP32-D0WDQ6-V3)：PULL UP with 100KΩ.
ATOM PSRAM (ESP32-V3-02)：PULL UP with 5.1KΩ.
M5Stamp Pico (ESP32-PICO-D4)：PULL UP with 5.1KΩ.

The library has been released!
It is a library that can be used in common with M5Stack / Core2 / Tough / CoreInk / Paper / StickC, CPlus.
Buttons, touch panel, IMU, 5V output on / off to external port, etc. are available. It can also be used with ESP-IDF.

Hello@F3l1x

In the example below I am using lcd-image-converter.
lcd-image-converter
https://sourceforge.net/projects/lcd-image-converter/
Select 8bit or 16bit for Block size and create xxx.c.
Use M5.Lcd.pushImage(x,y,imgWidth,imgHeight,(unit16_t *) xxx);

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.
