Hi there, Been getting started with the Uno32. Just connected an LCD display to my board, and now I have a red LED lit next to J4. Can't find anything to explain what this is for. I've loaded the 'Blink' sketch, and while it loads and runs ok, but the red LED next to J4 stays iluminated. Pressing the reset button doesn't change it.

I hope I haven't fried the board, as it was going so well.

// Angus You need to check the design reference drawing , LD3 is the 3.3volt indicator , (its a little bright ! )

Thanks for the reply. You're right it is LD3 that is lit. I'm afraid that I may have made a foolish first post. When I connected up a LCD screen I got a warning on my computer that the draw on the USB port was too high. I then plugged in an external power supply and noticed the red LED, and thought I'd done something wrong. I forgot that that LED is lit all the time. You right that it is a bit too bright.

Well now that I am slightly more relieved that I haven't blown the board, I'll carry on experimenting.

On FB3 XE i choose my stratup cue, made link to the next cue, and this one to the next cue and so on... which work very well when the computer is on and usb connected, but when I take the computer away just the startup cue is played not the next cues... What am I doing wrong ?

Angus, I disagree... We all have lapses in thought and its better to post and hopfully get a quick answer than to bang your head against the wall.
