1.0 INTRODUCTION
The DLP-PROP is a preassembled, USB-powered module for demonstrating the new Propeller chip
from Parallax in a standard 0.9-inch wide, 40-pin footprint. User electronics can be connected via the
28 unused I/O pins. The Propeller is clocked via a 6MHz external clock. Using the on-chip PLL in the
Propeller, the following clock frequencies can be generated internally: 6, 12, 24, 48, and 96MHz.
The DLP-PROP was developed to be fully compatible with Parallax’s new Spin programming
language and development environment. For detailed operating instructions, refer to the Propeller
Manual, available from the Parallax website.
2.0 PERMANENT SERIAL NUMBER
Each DLP-PROP module contains a unique, 32-bit, hard-coded serial number known as the “ChipID“
that cannot be altered by any means. This serial number can be read via the USB interface using the
D2XX drivers and used to identify the module via the host software.
If the DLP-PROP is configured for VCP driver use, it must first be reconfigured to use the D2XX
drivers by running MPROG before the serial number can be read.
3.0 APPLICATION DEVELOPMENT
Propeller software for compiling the Spin source code is available for download via the Propeller
Downloads page (http://www.parallax.com/propeller/downloads.asp). Any program written for the
Propeller will run on the DLP-PROP.
The latest version of the Propeller Manual is also available from this web location.
4.0 QUICK START GUIDE
This guide requires the use of a Windows XP, XPx64, Server2003, or 2000 PC that is equipped
with a USB port.
1.
2.
Download the combined Windows VCP / D2XX driver set from either www.dlpdesign.com or
www.ftdichip.com. Unzip the drivers onto a blank floppy disk or into a folder on the hard drive.
The DLP-PROP can be configured to receive its operating power from the USB port or from
user electronics. Pins 18 and 19 allow for this configuration. (Refer to the following Pinout
Description section for a detailed explanation of the DLP-PROP’s electrical interface.)
Note: The module will not operate until a power source has been selected as mentioned in
Step 2.
3.
Connect the DLP-PROP to the PC via a standard A-Mini-B, 6-foot USB cable. This action
initiates the loading of the USB drivers. When prompted, select the folder in which the device
drivers were stored in Step 1. Windows will then complete the installation of the device
drivers for the DLP-PROP module. The next time the DLP-PROP is attached, the
host PC will immediately load the correct drivers without any prompting.

Rev. 1.1 (October 2006)
Reboot the PC if prompted to do so. At this point, the DLP-PROP is ready for use.
Note: If you wish to change the driver type from VCP to DLL (or vice versa), you must run the
MPROG utility and change the setup information stored in the EEPROM. (This utility can be
downloaded from either www.dlpdesign.com or www.ftdichip.com.) The DLP-PROP is
shipped with default VID, PID, etc. values programmed into the EEPROM with the driver mode
set to VCP. You only need to run the MPROG utility if you want to change these default
values.

SW33V
(Out) 3.3-volt switched power from EXTVCC, controlled via CBUS4 of the FT232R and the
Q1 MOSFET power switch. R1 and C8 control the power-up rate to help limit inrush current. SW33V
becomes active after the host PC enumerates the module.

PORTVCC
(Out) 5-volt power from the host PC. Power from the host immediately exits the module
via this pin. If power from the host PC is to be used, this pin must be connected to EXTVCC.
EXTVCC
(In) Main module power input. 5-volt power must be applied to this pin for the module to
operate. Connect to PORTVCC if the module is to be powered by the USB port (typical
configuration). 500mA is the maximum current available to the DLP-PROP and target electronics if
the USB device is configured for high power.
