    I agree with the need for a little clarification in the docs… my (also recycled) Sharp LCD has a 2x7 (data) + 1x3 (backlight LED) header for the interface, so does not plug straight in… where is pin 1 on the backpack? There is a suspicious dot at the far end away from the serial/power screw terminals, but it IS NOT PIN 1!!!! There is a cryptic reference in the datasheet to pin 15/16 as being near the sparkfun URL, [which is not on the current board…] (but is in the image in the datasheet). Once I got that sorted, it works great! I would suggest a diagram included with the pinout doc that shows the pin orientations.
    Also on commands, it is still not clear to me what to send to program the LCD size, after the command byte (0x7C) do you send “3” [0x33] or 0x03? And how do you use the cursor (blink/underline) on/off? [which should also include the 0x09 command for blinking text?] I have the positioning commands working.

No public wish lists :(
