No loop?

[Cabzx]

Hey guys,

I am trying to get the matrix to work inside loops, but it won't comply. I am using the HowToUse example but I am adding "x;" to the loop.

Arduino: 1.8.3 (Windows 7), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

HowToUse.ino: In function 'void loop()':

HowToUse:112: error: 'x' was not declared in this scope

 void loop() { x; }

               ^

exit status 1
'x' was not declared in this scope

It seems that matrix declarations inside setup aren't read by the loop function. Just placing all matrix declarations as globals seems to have fixed the issue.
