#monobus

#OSC to Lawo MonoBus bridge

Control your Lawo MonoBus devices via an OSC server that talks to FTDI USB adapters.

#Dependencies

LV2 (LV2 Plugin Standard)
libftdi (Library to talk to FTDI chips)
netpbm (Toolkit for manipulation of graphic images)
ncurses (Free software emulation of curses)

#Build / install

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

#Usage

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

[user@machine ~] dmesg

#Control monobusd with your favorite OSC client

#/monobus/PRIO ,iiiib BITMAP-DATA

To set the bitmap, send your OSC messages to given OSC path with PRIO 0-31 integer x-offset, integer y-offset, integer width, integer height and blob argument being your bitmap data in PBM payload format.

# set bitmap of size 112x16 at offset position (8,12) for priority level 11
osc.udp://localhost:7777 /monobus/11 ,iiiib 8 12 112 16 {...}

#**/monobus/PRIO ,

To clear the bitmap, send your empty OSC messages to given OSC path with PRIO 0-31.

# clear whole bitmap for priority level 11
osc.udp://localhost:7777 /monobus/11 ,
