#osc2ftdidmx

#OSC to FTDI DMX bridge

Control your DMX devices via an OSC server that talks to FTDI-DMX USB adapters..

#Dependencies

LV2 (LV2 Plugin Standard)
libftdi (Library to talk to FTDI chips)

#Build / install

git clone https://git.open-music-kontrollers.ch/~hp/osc2ftdidmx
cd osc2ftdidmx
meson build
cd build
ninja
sudo ninja install

#Compatibility

Should be compatible with any FTDI-based USB-DMX adapter, e.g

#Usage

#Discover your type of FTDI-DMX device via e.g. dmesg when plugging it in

[user@machine ~] dmesg
[  132.718684] usb 1-1.4: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00

#Control osc2ftdidmx with your favorite OSC client

osc2ftdidmx supports 32 priority levels per channel. If priority level 0 on a given channel is set, and now priority level 1 gets set, the latter takes precedence. When priority level 1 is cleared, value is taken from priority level 0 again. If no priority level is set on a given channel, the channel's value is assumed to be 0.

#/dmx/[0-511]/[0-31] {i}+ [0-255]+

To set channels, send your OSC messages to given OSC path with integer argument(s) being subsequent channel/priority values.

# set channel 0, priority 0 to value 255
oscsend osc.udp://localhost:6666 /dmx/0/0 i 255

# set channel 12, priority 31 to value 127
oscsend osc.udp://localhost:6666 /dmx/12/31 i 127

# set channels 23,24,25,26, priority 1 to values 1,2,3,4
oscsend osc.udp://localhost:6666 /dmx/{23,24,25,26}/1 iiii 1 2 3 4

# set all channels, priority 3 to value 0
oscsend osc.udp://localhost:6666 /dmx/*/3 i 0

# set channel 0, priorities 0,1 to values 1, 2
# set channel 1, priorities 0,1 to values 3, 4
oscsend osc.udp://localhost:6666 /dmx/[0-1]/[0-1] iiii 1 2 3 4

# set channel 0, priorities 0,1 to values 1, 2
# set channel 1, priorities 0,1 to values 3, 3
oscsend osc.udp://localhost:6666 /dmx/[0-1]/[0-1] iii 1 2 3

# set channel 0, priorities 0,1 to values 1, 2
# set channel 1, priorities 0,1 to values 2, 2
oscsend osc.udp://localhost:6666 /dmx/[0-1]/[0-1] ii 1 2

# set channel 0, priorities 0,1 to values 1, 1
# set channel 1, priorities 0,1 to values 1, 1
oscsend osc.udp://localhost:6666 /dmx/[0-1]/[0-1] i 1

#/dmx/[0-511]/[0-31]

To clear values, send your OSC messages to given OSC path without any arguments.

# clear all channels, priorities
oscsend osc.udp://localhost:6666 /dmx/*/*

# clear channel 0-1, priorities 0-1
oscsend osc.udp://localhost:6666 /dmx/[0-1]/[0-1]
