grid module C code assumes 4 quads on device

[catfact]

the implementation of grid refresh in device_monome.c always assumes 4 quads of LEDs.

after a call to g.all(), all four quads are marked dirty, so 4x map messages will be sent on refresh.

this doesn't appear to cause any problems with most devices, but it seems like older/slower grid models might respond strangely. (flickering, etc.)

so we should probably teach device_monome to respect device size.

come to think of it, it would probably be a good idea to switch /led/level/map for /led/map on monobright devices. (i don't think libmonome directly exposes a query for monobright, but we can test the result of monome_get_proto() or something.)

[artfwo]

libmonome automatically translates led_level_map to led_map on monobright devices. why would you want to implement the brightness conversion in the client (matron)?

p. s. it's also possible to detect the varibright (mext) devices by id - it will always be mNNNNNNN or ^m\d+$

ok thanks. i hadn't got as far as looking in the protocols. so: i wouldn't!
