Hello,
nearly all examples run perfect within web editor. But VidorDrawLogo_copy produces no Video output, although I can read:
Success:Saved on your online Sketchbook and done uploading VidorDrawLogo_copy.
What to do ?
Is this perhaps a Monitor problem. (1280x1024 fh:64,2 kHz fV:60.2 Hz)
Double-tap the reset button to enter bootloader mode, that would do a quick test if video is ok.
The DrawLogo example waits until serial monitor is connected, and will stall until you open a connection.
Either do that, or comment out the waiting loop, so demo will run immediately.
