Hi, I'm new to the Arduino world and I just made a Lite-On LTM-8328PKR-04 4x7 LED segments display library.
Maybe it can be usefull to somebody else finding one in a junk bag
My lib doesn't support custom characters but that would be easy to implement as each segment is controlled individually.
I don't know where to get them as I only found one in a junk bag.
I really quite want one, I have been looking for one of these sort of things for a while as an easy way to display a menu on a DMX light i am building. Thankyou for bringing it up.
