I need to change the size of the ringbuffer (serial-input fifo of the ARDUINO DUE) from 64bytes to ~1000bytes. In the last version of the IDE that I was using I could change this in the file "ringbuffer.h", but I can't find "ringbuffer.h" in V1.6.3 anymore!?
Thanks for your help in advance!
If you are using windows then go to your user directory (c:\users\yourusername) then AppData\Roaming\Arduino15\packages\arduino\hardware\sam\1.6.3\cores\arduino
There you will find the files. Yes, that's a hugely deep directory structure. On OSX and linux the situation will be similar - in your user folder you'll find deeply buried directories.
