Programming Connection
System Testing
The PE Platform is a microcontroller system very similar to the ones you’ll find in common products
and specialized equipment.
prototyped, tested, modified and refined using pluggable breadboards before they are mass-produced
as one or more printed circuit boards and housed in metal or plastic cases.
The PE Platform itself has a number of subcircuits, including the Propeller chip itself, voltage
regulators, oscillator, EEPROM, power indicator, reset button and programming connections. All
these subsystems need to be tested to make sure that the PE Platform will perform correctly through
the upcoming labs. For these tests, a couple of simple circuits will be built on the PE Platform, and a
test program will be downloaded to and executed by the Propeller chip. By modifying both the test
circuit and test program, you will be able to verify all the PE Platform’s subsystems.
Test the Programming Connection
The first test uses the Propeller Tool software’s Identify Hardware feature. The battery should be
connected, and the Propeller Plug should be connected to the 4-pin header and your PC via the USB
cable.
An information window will appear with one of two messages:
When this feature is used, the Propeller Tool searches the available COM ports for a serial connection
to a Propeller chip. If the “Propeller…found…” message appears, it verifies three things: (1) The
USB virtual com port (VCP) driver is properly installed, (2) the Propeller Plug is functioning and
connected to the PC’s USB port, and (3) the PE Platform’s 4-pin Propeller Plug port is correctly
wired to the Propeller Chip. On the other hand, if the “No Propeller…found…” message appears,
there is a problem somewhere in the communication stream. In that case, Troubleshooting entry (6)
on page 11.
Test Circuit Parts List
For the next test circuits, you will need the following parts from the PE Project Parts bag:
•
•
(1) LED - Red, green or yellow
(1) Resistor - 100 Ω
(1) Resistor – 10 kΩ
(1) Pushbutton
(4) Jumper wires
Disconnect the battery, and plug in the Propeller Plug onto the 4-pin header as shown in
Figure 3, with the label side down. The power LED on the breadboard should glow dimly. If
it does not, go to Troubleshooting entry (5) on page 11.
Open the Propeller Tool, then from the Run menu select Identify Hardware… (or Press F7.)
“Propeller Chip version 1 found on COM…”
“No Propeller Chip found on any COM port. Scanned COM…”
