Memoji's

You can use the Memoji feature on iOS devices to create a custom animation. Record your facial expression to puppeteer a 3D character. We used the skull and ghost emoji's.

Recording & Saving Memoji's

Use the messages app on a capable iOS device to record and send the emoji. Save the recording to your desktop using iOS Message app. Drag and Drop the MP4 file to the desktop.

Export Image Sequence

Use an editing program such as Photoshop or After Effects to modify the scale or position. Set the canvas to 32 pixels height and 64 pixels wide. Set the frame rate between 12 and 24 frames. Export the MP4 video as an image sequence.

Sprite Sheet Bitmap

Use Aseprite to generate a sprite sheet image of the image sequence. Open the image sequence and export a sprite sheet image using vertical strip as the sheet type and bitmap as the image format.

Drag and drop the bitmap image to the bmps folder on the CIRCUITPY drive.

Walk through the sprite sheet animation learn guide for more information and instructions on using the Aseprite program.

Download the zip file below to use our "ready-to-go" bitmaps. These were created for 32x64 RGB matrix in a portrait / vertical orientation.
