Usage

Test the interface by sending DMX data

python .\check-dmx-interface-ftd2xx.py

Test OSC sending and receiving part

npm install socket.io
npm install osc-js

Run the the receiving and sending scripts in separate consoles:

python .\receive_osc_data.py 
node   .\send_osc_data.js     <target ip address: e.g. 192.168.0.8> 

Result:

python  .\receive_osc_data.py
Your Computer Name is:DESKTOP1234
Your Computer IP Address is:192.168.0.8
/audio/path: (42, 0.5529999732971191, 'hello')

Run the ligth show

WIP

First basic steps to control a light changes from Andorid OSC Controller App. Andorid device and the Windows PC must be in the same network.

python  .\receive_osc_send_dmx.py
Your Computer Name is:DESKTOP1234
Your Computer IP Address is:192.168.0.8

Configure the App: IP Adress: as provided by the python script Port: 8080 OSC Patch: /dmx

Configure parameters
