QMK compressed animation

Convert a sequence of PNGS or a GIF to a compressed QMK OLED animation.

Usage:

The most basic usage is python qmk-animation.py <directory | file>.
This will generate animation.h which contains the animation data and a function to change frames.

There are to additional arguments you can add -o <file_path> and -t <threshold>.
Setting -o changes the output file to the one supllied.
Settung -t changes the threshold the average pixel color should be greater than to be considered turned on.

Include in keymap

First include the animation header at the top of keymap.c.

#include "animation.h"

Then to render the animation you can add this function.

static int c_frame = 0;
bool first_render = true;

static void render_anim(void) {
    if (first_render) {
        oled_write_raw_P( frame, ANIM_SIZE);
        first_render = 0;
    } else {
        change_frame_bytewise(c_frame);
    }
    c_frame = c_frame+1 > IDLE_FRAMES ? 0 : c_frame+1;
}

Then this function can be used in the oled_task_user function.

Set animation speed

To set the animation speed add #define OLED_UPDATE_INTERVAL <time in ms> in the file config.h inside your keymap folder.
