I'm relatively new to the arduino world, have a lot to learn, but am having a blast. I have a Seeeduino Stalker with an AT328 and have successfully run a few of the demo sketches and interfaced into one of your danger shields. That's all well and good, however, I have recently taken the plunge and purchased one of the LCD Shields (Color LCD Shield sku: LCD-09363). Unfortunately, I am having some trouble with getting the demo code to run correctly and believe it is a hardware problem and am hoping you all can help.
I have been successful in getting the demo code to compile and upload this to the board. But that is about the extent of my success. When plugging the board in to the Stalker I get a bluish back-lit screen with nothing displayed. Perhaps, this is a Seeeduino issue but when I measure the voltage on the 6 pin header I do not receive any voltage on the 3.3V line. I believe this is because I am running the system off of the USB port. Can someone describe exactly which pins need to be powered and at what voltage to get the LCD Shield to function properly? Does it need both 5V and 3.3V? If so how do I rig the board to output both or is this a limitation with the Stalker? Any help you can provide would be great.
Cheers,
Brian
