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. This tracer include an enhanced version (support for several lasers) of the etherdream python library from j4cDAC. * 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.
