    I can't seem to search on .jpg or library without getting nearly everything out there. Those terms are too common. So I ask you humans.. Decoding .jpg and other common image files. What are the favorite libraries...

    The routine in question strips out un-dialable characters from a phone number string. So the resulting string is always shorter than the inputted one. All the strings either come from the user input or the SD drive so...

    Interesting. I recompiled this same program for an Adafruit Feather and it worked fine. Is there some compiler option that's allowing this on a Feather and not on a Teensy3.2? -jim lee
