Hi all
first post so pardon the noobiness...
my serial GLCD (128x64) is acting up big time. I uploaded summoningDark's firmware using an Arduino UNO as ISP (followed tutorial) and I thing something got borked.
The display starts up reversed and prints "white over black", can't get it back to normal. Reset, reverse color, nothing does the trick. The demo() function is gone so I think the firmware update was effective (says so in the FW README, demo gone), but then again, even before the update I couldn't get things like drawData(produces garbage characters) or toggleFont(no effect) to work. Commands just don't seem to go through, other than basic text printing.
This both via Arduino serial (TX-1) and NewSoftSerial. Strangely, with NewSoftSerial the display works on 9600 baud, not the default 115200.
Not sure what info I should provide more...
help!
