Is there some restricted naming convention for local include files? I named one mrstLCD.h and arduino cannot find it at compile time in local directory. I renamed it to xmtrasLCD.h and it found it. What is happening here? why would the name make any difference at all? either name shows up in the IDE.
Went back and forth a couple times and mtrasLCD.h never is recognized and xmtrasLCD.h is always recognized!
Any suggestions as to why some names work and others don't????
