alternative LCD shield
#1
Hallo,

I just tinker my miniEngine 1. Here I bought by mistake instead of the DFRobot LCD Keypad Shield the shield described under http://www.microbot.it/documents/mr007-005_datasheet.pdf.

Can this be used without changing the software? Airic does not know this shield.

As mentioned - if the both are pin compatible it should work:

DFRobot Shield
Pin 4-7    -> LCD Data transmission
Pin 8       -> Reset pin
Pin 9       -> Enable pin
Pin 10     -> Backlight control

Your shield:
Pin 7     RS - Register select

Pin 6     E - Enable
Pin 5     D4 - High 4-bit data
Pin 4     D5 - High 4-bit data
Pin 3     D6 - High 4-bit data
Pin 2     D7 - High 4-bit data
Pin A0   Analog Input for buttons readings

For me that looks like the code might need some changes for your shield Wink
