# Waveshare ESP32-S3-Touch-LCD-4B — doorbell JPEG viewer
# Copy this file AND the components/ folder into your ESPHome config directory.
# Pair with the resizer proxy in this repo.
#
# Touch cycles: stream A (default) -> stream B -> off -> stream A ...
#
# Uses a custom fast_jpeg component (RGB565 block decode + DMA blit).
# Stock online_image JPEG is too slow for ~5 fps.
