blync light device manager
here's a quick cap for now:
- run daemon as root
- default listen port is tcp 4545
- per-connection command sessions
- use command "." to terminate socket from server side
- list devices and their aliases with command "d"
- list colors with command "c"
- set colors with command "s"
- set a device alias with "a"
to get started quickly, connect your devices and ensure they're powered (check dmesg), label them A-Z
run make and then sudo ./a.out --debug and blyncd will list their device IDs in the console
use the set command to turn them all on (white) to make sure they're working
$ echo "s1" | nc localhost 4545
turn them off again with "s0" and then turn them on one at a time using a device ID
$ echo "s1,0001:0013:01" | nc localhost 4545
identify the label on the lit device and then assign it and turn them off
$ echo "ax,0001:0013:01s0" | nc localhost 4545
now repeat this procedure until all the labels are matched with device IDs. when you're done you can verify your work with the device list, as it shows the current alias, if any, for each device
$ echo "d" | nc localhost 4545
0001:0013:01 x
0001:0014:01 y
0001:0015:01 z
now you're ready to sequence! write a program to open a socket and begin streaming setcolor commands to blyncd with whatever timing is appropriate to your application!
"s1,xs0s2,ys0s3,z" ...
note that if you use a line-oriented protocol, the whitespace will cause delay, probably on the scale of micro- or milliseconds, as it is shunted into the lookahead buffer (one character deep) and comes "back around" to the top level of the stream parser before being discarded.
here we have the Very Small Blynclight Array:
