- Add n4 parameter to control server, LED bar receiver, and test script - Create segmented_movement pattern with alternating forward/backward movement - Pattern supports n1 (segment length), n2 (spacing), n3 (forward speed), n4 (backward speed) - Fix test script to send all messages instead of just the first one - Add segmented_movement to patterns_needing_params for proper parameter transmission - Pattern intelligently handles all cases: alternating, forward-only, backward-only, or static - Implements repeating segments with configurable spacing across LED strip

"""
|
|
Test script for control_server.py UI WebSocket API.
|
|
|
|
Starts a client to localhost:8765 and sends a small sequence of UI commands:
|
|
- pattern_change
|
|
- color_change
|
|
- brightness_change
|
|
- parameter_change (n1/n2/n3/n4)
|
|
|
|
Usage examples:
|
|
python test/test_control_server.py --pattern on --r 255 --g 0 --b 0 --brightness 150 --n1 5 --n2 5 --n3 1 --n4 2
|
|
python test/test_control_server.py --pattern rainbow
