How To Slideshow Images on OLED?

Arduino: Seeed Studio XIAO SAMD21: Seeed Studio XIAO Series
OLED: SH1106 128x64 Monochrome OLED

Basically trying to figure out how to make the OLED display a sort of Slideshow of images. So far I have to images in the code ("overclock" and "bulletproof"), but not sure how to set a delay and then move on to the next image. In the end I'll have about 8 images to cycle through.

#include <Wire.h>
#include <U8g2lib.h>
//#include <Arduino.h>

// ---> Pin connections
#define SCL_OLED A5
#define SDA_OLED A4

//[page buffer, size = 128 bytes]
U8G2_SH1106_128X64_NONAME_1_SW_I2C OLED(U8G2_R0, SCL_OLED, SDA_OLED, /*reset=*/U8X8_PIN_NONE );
//U8G2_SH1106_128X64_NONAME_1_HW_I2C OLED(U8G2_R0);
//U8X8_SH1107_128X128_4W_HW_SPI u8x8(/* cs=*/ 10, /* dc=*/ 9, /* reset=*/ 8);

// 'overclock', 128x64px

No. You are not understanding the model for drawing the screen

OLED.firstPage();
do {

// code that draws one screen

} while ( OLED.nextPage() );

This runs as many times as needed, and executes your code (or calls your function) every time, each time painting a bit more of the screen.

You can't change horses in the middle of that stream, so to speak.

Try

void loop() {

  myDraw(0);

  delay(777);

  myDraw(1);

  delay(777);

}

void myDraw(int what)
{
  OLED.firstPage();
  do {

// what are we drawing this time?

    if (what == 0)
      OLED.drawXBMP(0, 0, 128, 64, overclock);

    if (what == 1)
      OLED.drawXBMP(0, 0, 128, 64, bulletproof);

  } while ( OLED.nextPage() );
}

Sry, I can't test this, but this is your problem.

It is an awkward system, but needed to reduce the memory requirements - a large screen can be done with a small buffer covering some fraction of the screen, it just needs multiple passes through the do loop.

If you have eight, you could use an array of the pages data to be drawn, or do it like I did but use maybe a switch/case statement.

Lemme know this works. If there are compiler errors I can try to fix them.

Aside from a stray colon instead of semicolon on the myDraw(1), what you gave me worked. Thank you!

What stray semicolon colon? :wink:

Happy to help, glad you could catch and fix that, sry.
