• 2 servomotors for pan-tilt-LED

host: raspberryPi3 with start button on GPIO-0 (pin 11 of 40-pins header)

network remote Pd patch:

• set LEDs/motors
• record/save-to-file/replay from/to OSC

Installation

Machine:

Install Pure Data (v >= 0.47-1)
Install Fraise
Install Pd externals:

• maxlib
• ggee

Download project zipfile (from github's page), extract.
Open with Pd : 0main.pd

Configure the rPi: (optionnal)

• set hostname : Chimere
• autostart "pd 0main.pd"
• read-only file-system
• WIFI access point:
  • network name: AP-Chimere
  • password: raspberry
• static eth0 IP: 192.168.1.71

Remote client:

Install Pure Data (v >= 0.47-1)

Download project zipfile (from github's page), extract.

Connect to the raspberryPi either through ethernet or to WIFI access point:

• network name: AP-Chimere
• password: raspberry

Open with Pd : 0remote.pd

If the client doesn't connect to the machine:

In 0client.pd, open sub-patch named pd guts; locate the object:
PdClient CLIENT CLIENT Chimere.local

In edit mode, change Chimere.local to the IP address you can ping the machine host. Try 192.168.3.1 if WIFI connected, or 192.168.1.71 if ethernet. Connection should be established almost instantly. Save the patch when working.

OSC names:

lyre 1:

• 1R:rotation
• 1X:pan(in radians -100°/+100°)
• 1Y:tilt(in radians -60°/+140°)
• 1L1:LED1(0-10)
• 1L2:LED2(0-10)
• 1L3:LED3(0-10)
