Use basic unix IO and liblo to make a driver that will read the device and output Open Sound Control messages. The C program reading th usb device will act as the client and the Chuck shred will be the server.
Program flow
- init liblo
- read command line parameter
- open device
- output message "connect to device"
- loop:
- read device
- process input
- send osc message
- check for exit condition
- tidy up
- exit
Building
Download liblo from sourceforge
curl -O http://waix.dl.sourceforge.net/sourceforge/liblo/liblo-0.25.tar.gz tar xzf liblo-0.25.tar.gz cd liblo-0.25 ./configure make && make install
Need to tell the linker where to find the newly installed libs
ldconfig /usr/local/lib
Add this Makefile
all: gcc -llo drumkit.c -o drumkit
And build it.
make
Check it linked correctly - you should NOT see this:
liblo.so.0 => not found
more like
liblo.so.0 => /usr/local/lib/liblo.so.0 (0xb7fc9000)
