Brief history... About a month ago; I upgraded from Arduino 1.6.4 to 1.8.4 I had trouble with it, so I copied all my sketches to a backup folder. Then deleted 1.6.4, followed by installing 1.8.4
I have several sketches for the GPS, oled display. I went on a cruise back in the beginning of Sept. So I uploaded the boat sketch to my Trinket. Last week, I decided to copy my GPS Speedometer sketch back to the Trinket.
The fonts are not the same as before(larger). No big deal, I figured out how to change the fonts, move the data around to fit the screen.
I can't figure out why the sketch no-longer displays the number of satellites. Was there a change in the Library/header files?

Admins: should I just tack this on to my previous thread (Adafruit Ultimate GPS, SSD1306 0.96" 128x64 OLED, Arduino Uno sketch problems - Project Guidance - Arduino Forum)? Or is this ok?
Well, since you have a new version now...
