One tracer process is launched per requested laser by LJ. Lasers parameters in LJ.conf.
|
||
|
|
Live I/O based on redis keys : inputs (Pointlists to draw,...) and outputs (DAC state, errors,..).
|
||
|
|
Keys are mostly read and set at each main loop.
|
||
|
|
|
||
|
|
* Redis keys reference *
|
||
|
|
|
||
|
|
- Drawing things :
|
||
|
|
|
||
|
|
/pl/Scene/lasernumber [(x,y,color),(x1,y1,color),...] The live list of drawn pygame points. Tracer continously ask redis for key /clientkey+lasernumber
|
||
|
|
/resampler/lasernumber [(1.0,8), (0.25,3),(0.75,3),(1.0,10)] : a string for resampling rules.
|
||
|
|
the first tuple (1.0,8) is for short line < 4000 in etherdream space
|
||
|
|
(0.25,3),(0.75,3),(1.0,10) for long line > 4000
|
||
|
|
i.e (0.25,3) means go at 25% position on the line, send 3 times this position to etherdream
|
||
|
|
/clientkey "/pl/SceneNumber/" What Scene to retrieve from redis
|
||
|
|
/EDH/lasernumber
|
||
|
|
|
||
|
|
- Tracer control :
|
||
|
|
|
||
|
|
/order 0-8 Set redis key with new value then issue the order number
|
||
|
|
|
||
|
|
0 : Draw Normal point list
|
||
|
|
1 : Get the new EDH = reread redis key /EDH/lasernumber
|
||
|
|
2 : Draw BLACK point list
|
||
|
|
3 : Draw GRID point list
|
||
|
|
4 : Resampler Change (longs and shorts lsteps)
|
||
|
|
5 : Client Key Change = reread redis key /clientkey
|
||
|
|
6 : Max Intensity Change = reread redis key /intensity
|
||
|
|
7 : kpps change = reread redis key /kpps
|
||
|
|
8 : color balance change = reread redis keys /red /green /blue
|
||
|
|
|
||
|
|
|
||
|
|
- Managing Etherdream DACs :
|
||
|
|
|
||
|
|
Discrete drawing values
|
||
|
|
|
||
|
|
/kpps 0- DAC output speed to laser, then order 7. Depends of actual angle
|
||
|
|
/intensity 0-255 Laser output power, then order 6 (for alignement,...)
|
||
|
|
/red 0-100 % of full red, then order 8
|
||
|
|
/green 0-100 % of full green, then order 8
|
||
|
|
/blue 0-100 % of full blue, then order 8
|
||
|
|
|
||
|
|
DAC status report
|
||
|
|
|
||
|
|
/lstt/lasernumber etherdream last_status.playback_state (0: idle 1: prepare 2: playing)
|
||
|
|
/cap/lasernumber number of empty points sent to fill etherdream buffer (up to 1799)
|
||
|
|
/lack/lasernumber "a": ACK "F": Full "I": invalid. 64 or 35 for no connection.
