![]() The PIC does not have the brown-out fuse enabled, meaning I need to physically disconnect the display when I wish to reset it after a command. The schematic doesn't match the actual device - there are ~13 other components on the board not shown. Search google and you'll find many people can't get this display to work on an Arduino that has a shield. If you turn on the backlight, the electrical interference is so bad that if your power jumper to the board is more than a few cm the display will often fail to accept commands properly. ![]() This is practically an oscillating antenna! There is only a single 0.1uF cap to suppress this noise - but its at the very end of the wire and definitely not enough for this current. The power line stretches some 15" before it reaches the PIC, while at the same time suffering from 150mA+ PWM. I strongly recommend anyone interested in this display to not buy it.
