 When reporting any issue, please try to provide complete information.  The following are almost always needed:
 
 - A complete copy of the code (which can be copied into Arduino and run on a Teensy board) which reproduces the problem is usually needed to investigate any issue.  Please try to trim your program to the minimum necessary, ideally not depending on extra hardware if possible.  But a complete program that can be copied into Arduino without guesswork is essential.  Please do not submit this Github issue with only code fragments or a vague description of code to recreate the issue.
