Tracer
|
|
for LJ v0.8.2
|
|
|
|
Enhanced version (support for several lasers) of the etherdream python library from j4cDAC.
|
|
One tracer process is launched per requested laser. I/O based on redis keys.
|
|
|
|
LICENCE : CC
|
|
Sam Neurohack, pclf
|
|
|
|
Uses redis keys value for live inputs (Pointlists to draw,...) and outputs (DAC state, errors,..).
|
|
Most of redis keys are read and set at each main loop.
|
|
Includes live conversion in etherdream coordinates, geometric corrections,...
|
|
Etherdream IP is found in conf file for given laser number. (LJ.conf)
|
|
|
|
Redis keys to draw things :
|
|
/order select some change to adjust. See below
|
|
/pl/lasernumber [(x,y,color),(x1,y1,color),...] A string of list of points list.
|
|
/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
|
|
|
|
|
|
Redis keys for Etherdream DAC
|
|
|
|
- Control
|
|
/kpps see order 7
|
|
/intensity see order 6
|
|
/red see order 8
|
|
/green see order 8
|
|
/blue see order 8
|
|
|
|
- DAC status report
|
|
/lstt/lasernumber value etherdream last_status.playback_state (0: idle 1: prepare 2: playing)
|
|
/cap/lasernumber value number of empty points sent to fill etherdream buffer (up to 1799)
|
|
/lack/lasernumber value "a": ACK "F": Full "I": invalid. 64 or 35 for no connection.
|
|
|
|
|
|
|
|
Order
|
|
|
|
0 : Draw Normal point list
|
|
1 : Get the new EDH
|
|
2 : Draw BLACK point list
|
|
3 : Draw GRID point list
|
|
4 : Resampler Change (longs and shorts lsteps)
|
|
5 : Client Key change
|
|
6 : Intensity change
|
|
7 : kpps change
|
|
8 : color balance change
