Displaying a bitmap image

[Drom0s137]

I have a bitmap of a picture as follow generated from: http://javl.github.io/image2cpp/

// 'IMG_0263', 128x32px
const unsigned char epd_bitmap_IMG_0263 [] PROGMEM = {

};

// Array of all bitmaps for convenience. (Total bytes used to store images in PROGMEM = 528)
const int epd_bitmap_allArray_LEN = 1;
const unsigned char* epd_bitmap_allArray[1] = {
    epd_bitmap_IMG_0263
};

How would I go about displaying this on a 128x32 oled screen?

[nopnop2002]

S6D1121 is monochrome.

Therefore, it cannot be displayed neatly.

If you want to display an image, you need 128x32 bits of data instead of 128x32 bytes.

There is example using python. https://learn.adafruit.com/monochrome-oled-breakouts/python-wiring

@nopnop2002 Is there a way to do it in c using the setup from this repo?

[nopnop2002]

At this time, this repository does not support images.

This is because the image cannot be displayed neatly in grayscale.

You can see some samples by searching [ssd1306 image].
