timmfisk:
Has anyone experienced a problem with the reset button (or any other button?) with the DFRobot 16x2 LCD Display and Keypad Shield?
I have two of these units attached to a UNO R3 (two of each). On one of them, when I press the Reset Button, the LCD text becomes garbled and pressing buttons does not correct the issue. When I remove the power and then boot up again, all appears normal until the Reset Button is pushed... again... garbled text.
The board, components and the solder looks very good, no visible defects anywhere. When attached to the UNO R3, none of the soldered items are grounded.
Attached is the code I am working with
No problems here so far. I have four clones of the DFRobot "LCD Keypad Shield" which I ordered within the last four years at different vendors in China.
Two of my LCD Keypad Shields show white characters on blue background
Two other LCD Keypad shields show black characters on yellow-green background.
The LCDs with white chacters need the !backlight always ON" or the visibility will fade away after some time.
The LCDs with black characters can be operated with or without backlight.
All of them working pretty fine when used with a suitable sketch.
