Hi all,
how can I upload code in STAMP PWR485??

I'm in Arduino env.

Hi all,
I'm trying to use the unit fader with an old M5Stick gray

but analog read on pin 13 or 25 seems to be impossible during WIFI operation.....

can I assign pin 13 or 25 to ADC1??

best regards

@macsbug said in ATOM Lite Display not display in smallHd 503:

1920/2,1080/2,24

No way to display something on the 503.... I tried all configuration:

// M5AtomDisplay display(); // 1280 x 720
M5AtomDisplay display(1920,1080,24); // 1920 x 1080 , 24bit
// M5AtomDisplay display(1366,768); // 1366 x 768
// M5AtomDisplay display(1920/2,1080/2,24);
// ( 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);

when I connect hdmi cable to the 503, the monitor "feel" something (green led on and image settings in the "in settings page" of 503) but no image displayed.....

the same cable works in other setup....

Hi all,

somebody knows ATOM Display Lite settings for display on SmallHD 503 monitor?

best regards

noOne?

Hi all,
someone with a working arduino code for M5UnitOLED using U8g2 Library?

Using this constructor, I can display things but it is a little triky to calcolate positions, rotates and mirror...

U8G2_SH1107_SEEED_128X128_F_SW_I2C u8g2(U8G2_MIRROR, 32, 26,U8X8_PIN_NONE);

I'm with ATOM LITE...

tnks a lot..

@m5stack said in Change I2C pin in M5GFX Library (to use With ATOM LITE):

if you wanna change the I2C pin. you could use this code.

#include <M5UnitOLED.h>

//M5UnitOLED display; // default setting

M5UnitOLED display ( 21, 22, 400000 ); // SDA, SCL, FREQ

tnks a lot !!!

Hi all,
I saw a seven segment font in the M5GFX library but I dont understand How to call it in
canvas.setFont() function....

I need to display 4 digit in 7 seg style with a dot in the middle (es: 25.10) as big as possible...

tnks in advance...

tnks a lot !!!!
this sketch is working for me

#include <M5UnitOLED.h>
M5UnitOLED display ( 26, 32, 400000 ); // SDA, SCL, FREQ
M5Canvas canvas(&display);

static constexpr char text[] = "Hello world ! こんにちは世界！ this is long long string sample. 寿限無、寿限無、五劫の擦り切れ、海砂利水魚の、水行末・雲来末・風来末、喰う寝る処に住む処、藪ら柑子の藪柑子、パイポ・パイポ・パイポのシューリンガン、シューリンガンのグーリンダイ、グーリンダイのポンポコピーのポンポコナの、長久命の長助";
static constexpr size_t textlen = sizeof(text) / sizeof(text[0]);
int textpos = 0;
int scrollstep = 2;

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

  if (display.width() < display.height())
  {
    display.setRotation(display.getRotation() ^ 1);
  }


  canvas.setColorDepth(1); // mono color
  canvas.setFont(&fonts::lgfxJapanMinchoP_32);
  canvas.setTextWrap(false);
  canvas.setTextSize(2);
  canvas.createSprite(display.width() + 64, 72);
}

void loop(void)
{
  int32_t cursor_x = canvas.getCursorX() - scrollstep;
  if (cursor_x <= 0)
  {
    textpos = 0;
    cursor_x = display.width();
  }

  canvas.setCursor(cursor_x, 0);
  canvas.scroll(-scrollstep, 0);
  while (textpos < textlen && cursor_x <= display.width())
  {
    canvas.print(text[textpos++]);
    cursor_x = canvas.getCursorX();
  }
  display.waitDisplay();
  canvas.pushSprite(&display, 0, (display.height() - canvas.height()) >> 1);
}
