I have followed what you told to do at https://learn.adafruit.com/spokepov/customize
. However, when I pressed 'connect,' this wheel panel which you mentioned didn't showed up in my screen, and therefore I couldn't do it.
Another problem is that the program crashes when I import a BMP image file.
I've tried both Mac OS, Windows with my mac and with a windows PC. Therefore I think that the problem isn't my POV.
Could I please get an answer in 24hours? I have this school festival and I have to solve this problem quickly as possible. Thanks.
