- LEDs D3-D6, D13, D15 and D19-D20 will blink on and off in a binary sequence, with
D13 the MSB and D3 the LSB. The LCD will display “FF” in the right-most two digits.
- The voltage across the two pins of J8 will measure 2.5V +/- 1%.
- The voltage across the two pins of J7 will measure 1.2V +/- 1%.
Demo 3 – Test DIP Switches SW9-SW10
Demo 3 continues to exercise the digital inputs and outputs of the Platform Manager.
Two of the DIP switches are connected to the digital inputs of the Platform Manager.
As these DIP switches are turned on or off, the LCD will display two hexadecimal digits
corresponding to the values produced by the four bits of each DIP switch.
• One by one, move DIP switches SW9-SW10 from the off/up position to the on/
down position, and then back to the off/up position.
- The LCD will display corresponding hexadecimal characters representing the
hexadecimal value of each DIP switch as it is moved. The value will change
for each switch setting, as shown in the table below. Other values may be created
by depressing more than one switch at a time.
Demo 4 – Test All Segments of the LCD Display
Similar to Demo 3, Demo 4 also uses digital inputs. In this step, one of the push-buttons
which is connected to a digital input causes the LCD controller to display a looping
sequence of numbers from 111-FFF. This sequence repeats on the LCD as long as the
push-button is depressed.
• Press and hold PB_B_SW2.
- The LCD display will show a counting sequence from a blank display, through
111, 222, 333 … FFF, and will repeat. The count may start anywhere in the sequence.
