When _displayLength (sixth argument to constructor) is greater than 32, the library sends gibberish to the attached string of HCMS-2915 display modules.
I have a string of eight HCMS-2915 modules, daisy-chained in a chain of 8 modules, for 64 characters. When I call the constructor, with a _displayLength of 64, the displays show gibberish in the first 4 modules, and nothing (blank) in the following 4 modules. The gibberish is fixed in that it does not change over time (the code driving these displays was derived from the scroll_multiple example, and should be scrolling, but the gibberish does not change over time).
