11 Hardware Testing & Development

12 The LCD Connections

13 LCD Problems Rabbit port voltages? Rabbit Software? LCD component? Incorrect Logic?

14 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

15 LCD Test Schematic

16 The Keypad

17 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. The Keypad Connections

18 Timeline February 15, 2002 – Complete Research on Changes for Final Product March 1, 2002 – New Parts Ordered March 15, 2002 – PCB, Other Hardware & Software Changes Designed April 15, 2002 – Final Product Built May 1, 2002 – Testing Completed
