Hi,
Kindly excuse my newbieness.
I am using ESP8266 Huzzah with LSM9DS0 to send data to my laptop for processing sound in Supercollider using OSC protocol.
It works, ...thanks to much help.
Unfortunatly, my friend is away and I have exhausted my own searching.
He gave me a sketch which should enable me to connect the boards to any wifi network and run everything together.
I am aware that in the sketch I need to enter: the ssid, password and IP address of my computer on the network.
However, when I upload the sketch using a different wifi network, I receive this message:
[i]Users/petervukmirovicstevens/Documents/Arduino/huzzah_to_sc/huzzah_to_sc.ino:4:57: fatal error: OSCMessage.h: No such file or directory
#include <OSCMessage.h> /// https://github.com/CNMAT/OSC
^
compilation terminated.
exit status 1
Error compiling for board Adafruit Feather HUZZAH ESP8266.[/i]
However, when I upload a simple sketch, Blink for example on the different network, it uploads just fine.
This leads me to believe there is something in this sketch that needs changing.
I have attached the .ino sketch, but in the event that is not helpful, below is the pasted code.
I very much appreciate the assistance.
Peter
