![]() ![]() ![]() Arduino Sketchīefore we continue the Arduino Sketch a few details about the OSC protocol and TouchOSC need to be discussed. ![]() The label will display the value to which the slider has moved. It wl also send an OSC message to the little label in the upper right corner above the fader. The Arduino Sketch will receive the message and will print the value received with the message in the Serial Monitor. When the Fader is moved it sends OSC messages corresponding to its position to the Arduino Sketch. When designing your own controls it is important to note that for this toggle button to respond to OSC messages “Local feedback off” bust be checked in the editing properties in the TouchOSC Editor. The sketch will then send a message back to the control that turns the inside field on the button red to indicate that indeed the message has been received, a message has been printed and the LED is on. When the button is pressed it will send an OSC message to the Arduino Sketch to turn on the LED on the Arduino board and to print a message in the Arduino IDE Serial Monitor. The Arduino will send a message back to the controls and the Controls will respond to these messages. Both of these controls will send OSC messages to the Arduino. The layout has two pages, one with a simple button and one with a fader. Follow the online instructions and transfer the layout that you downloaded from the Github repository to your mobile device. Mac OSX comes pre-installed with one so this will not be discussed here. This is an application written in Java and needs a Java run time engine on your computer. We’ll use the Layout transfer over WiFi, which requires the TouchOSC editor to be installed on your computer. One includes transfer over WiFi while the other involves iTunes. The first thing that needs to be done is to move the layout from your file explorer to your mobile device. The complete Arduino sketch and TouchOSC layout can be downloaded from the GitHub repository. TouchOSC and the TouchOSC editor for your operating system.Teensyduino if you are working with a Teensy.Oscuino is the most complete implementation of the OSC protocol and is written and actively maintained by the inventors of the OSC protocol at the CNMAT | The Center for New Musik and Audio technology and the University of California at Berkley This is recommended over any other Arduino OSC implementations such as ArdOSC Z-OSC etc. OSC messages OTOH should work fine and this would be a physically very small solution! As such Bonjour also will not work with this setup. This does not allow for service registration. However, the Texas instruments CC3000 WiFi Chip/Module that is utilized the Sparkcore only implements a very rudimentary subset of multicast DNS (mDNS). I did some quick and admittedly sloppy research and I believe based on this Sparkcore Forum post that the Oscuino library has been successfully ported to also run on the Sparkcore. This should also work nicely with a Sparkcore. It may be possible to get this to work, but I have decided to use my limited time for something else □ Installing Avahi – the Linux implementation of ZeroConf Networking requires more memory than these small routers have. Open-WRT is Linux based and does not support Bonjour out-of-the-box. This only works with these two little routers with the original firmware. I’ve persevered through the Chinese and have worked successfully with the 703n as well as the 702n.Ī note of caution: In the section below “What’s left to do” I mention that this setup also can be made work nicely in conjunction with Apple’s Bonjour. However, out-of-the-box the interface is in Chinese. The TL-WR703n that is also available cheaply on eBay has a more capable processor and is popular amongst people that want to run the Linux based Open-WRT router software on the little router. The web interface that is used to configure these routers is in English. If a WiFi solution is desired the simplest solution is to connect a little pocket WiFi router such as the TP-Link TL-WR702n or TL-MR3020 to the Ethernet shield or module. This has been tested with an original Arduino Ethernet Shield on an Arduino Uno and with the WIZ820io Ethernet Module in conjunction with a Teensy 3 The Seeed Studio Ethernet Shield V2.0 for example hosts the W5200 Ethernet Chip and comes with it’s own version of the Ethernet Library that supports the W5200 chip. A word of caution: the standard Arduino Ethernet library does not support the W5200 Ethernet Chip so if you want to use a clone with a W5200, make sure it’s supported with a version of the Ethernet library. As long as these host a W5100 or W5200 Ethernet chip it should work. There are several clones of the original shield available in different price ranges. This was tested with an Arduino Uno, and a Teensy 3 This little tutorial describes how to control an Arduino with TouchOSC. ![]()
