Custom Emojis

Put your custom PNG files in png/ and custom GIF files in gif/.

The filename without extension is used as the emotion name. Directory names are not part of the emotion name, so png/neutral.png is loaded as neutral.

The display code looks up images by names such as:

neutral.png or neutral.gif
happy.png or happy.gif
sad.png or sad.gif
angry.png or angry.gif
thinking.png or thinking.gif
confused.png or confused.gif
surprised.png or surprised.gif
shocked.png or shocked.gif
sleepy.png or sleepy.gif
relaxed.png or relaxed.gif

Recommended minimum set:

neutral
happy
thinking
sad
angry

If an emotion-specific image is missing, the firmware falls back to neutral before using the built-in icon.

For Zhengchen CAM boards, the build selects one subdirectory:

CONFIG_ZHENGCHEN_CAM_USE_GIF_EMOJI=y: use gif/
unset CONFIG_ZHENGCHEN_CAM_USE_GIF_EMOJI: use png/

After adding or replacing files, run a full flash so the assets partition is updated:

idf.py flash
