  • I have been examining some strange behaviour I am seeing with these devices such as unintentional dimming of the backlight, strange characters displayed, and tripping of the reset circuit.
    I tracked the problem down to a sudden jump in current consumption from 20mA to 200mA (backlight off, 7V supply) when writing chars to the last row of the display. The current consumption remains at 20mA when writing X’s to the LCD, until I reach the last row.. Software bug?
    Overall I am impressed with price and how easy these serial LCDs are to work with. I figure a software modification might fix this? (These LCDs came with software edited on 5/11/10)

No public wish lists :(
