Talk:USB Roll-up drum kit user-space driver for linux

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.

• Client example for liblo
• OSC examples for Chuck
• JACK MIDI driver for drumkit

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

cat > Makefile
all:
	gcc -llo drumkit.c -o drumkit
(ctrl-d)

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)
