The LCD Connections
LCD Problems
•Rabbit port voltages?
•Rabbit Software?
•LCD component?
•Incorrect Logic?
•Eliminate possible logic errors.
•Use equipment that is trusted to work.•PC Parallel port.
•Minimize connections to the tested piece.
•Test all connections to the tested piece.
•If possible, use software which is known to work.
LCD Test Plan
LCD Test Schematic
The Keypad
•Rows connected to logic high on port D.
•Columns connected to logic low on port B.
•Rows and Columns were connected via 10k
current limiting resistor.
•Rows were tied to ground.•Columns were tied to Vcc.
