Open Sound Control (OSC) library for the ESP8266/ESP32
4
+
5
+
Example for receiving open sound control (OSC) messages on the ESP8266/ESP32
6
+
Send integers '0' or '1' to the address "/led" to turn on/off the built-in LED of the esp8266.
7
+
8
+
This example code is in the public domain.

+
Changes:
11
+
12
+
T.Goerke 05/18
13
+
- combined send & receive
14
+
- OSC messages can be used to set outgoing osc server (last octet) & port (optional)
15
+
16
+
Example: (using https://github.com/nulltask/osc-cli)
17
+
18
+
NoceMCU IP OSC IP
19
+
pi@nodered:~$ osc --host 192.168.1.207:8888 /osc 215 9999
20
+
OSC Port
21
+
22
+
- add MPR121 cap sensor board
23
+
- send NoteOn & NoteOff OSC messages to Renoise
24
+
- (send Analog Filter Cutoff to renoise)
