Work in Progress

Displays an RTP/JPEG stream on a Smalltv-pro (240x240 px LCD).

The roll-your-own minimal RTP/JPEG stack incl. jitterbuffer also runs on Linux and is fully tested and fuzzed.

Build and deploy

This is an ESP-IDF 5 project.

source $IDF_PATH/export.sh
export ESPPORT=/dev/ttyACM0

# Configuration
cp sdkconfig.defaults.ci sdkconfig.defaults
# Now, change default config (e.g. WiFi credentials):
idf.py menuconfig
idf.py save-defconfig

# Build/flash
idf.py build flash

# Lint/format
./format.sh

# Flash and monitor
idf.py -p $ESPPORT flash monitor

# Send frames
