The FlashFly System

FlashFly is an innovative system that allows a user to remotely download BASIC Stamp programs to Parallax’s Stamp modules or interpreter chips. FlashFly’s wireless capabilities, in coordination with common Series 1 XBee modules, will allow a user with a BASIC Stamp mobile robot or stationary platform to modify his or her program remotely.

Therefore, individuals who have mobile robots, sprinkler systems, weather stations, alarm systems, or any other remote or fixed controller board with a BASIC Stamp core will benefit from the FlashFly system because wirelessly downloading a program change is now achievable and easy.

FlashFly eliminates the tedious task of having to connect a robot or a fixed platform to a computer before any programming changes can be made. FlashFly also enriches a user’s learning experience by providing instant feedback data to the DEBUG terminal screen, which allows a user to evaluate his or her program flow and I/O data wirelessly. FlashFly can also be used in conjunction with any other microprocessor platform that needs to transmit data wirelessly.

The two main components of the FlashFly system are the Base Module and the Remote Module. These two modules are responsible for communicating back and forth. In the FlashFly system, there are three options for the Remote Module component. Each of these options will allow for wireless downloading of BASIC Stamp programs.

1. The Remote Module can be inserted into a breadboard or user-defined board for direct communication with a BASIC Stamp interpreter chip.

2. The RS-232 serial adapter board can be used in the FlashFly system to connect to a mobile or fixed platform when the user has a serial BASIC Stamp version (a board that uses a DB-9 connecter).

3. The USB Stamp adapter module can be used in the FlashFly system to connect to the Remote Module when the user has a USB-type board with BASIC Stamp.

The following list identifies each of the FlashFly system components, their respective product numbers, and their role in FlashFly. The last two boards are interchangeable, depending on the BASIC Stamp version a user has.

Base Transmitter Board (BWR-001-101) – This board connects to the computer.

Remote Receiver Board (BWR-002-101) – This board connects to a mobile or fixed robot.

RS-232 Adapter Board (BWR-003-101) – This board connects to the remote board.

USB Stamp Adapter Board (BWR-004-101) – This board connects to the remote board.




This is a low-cost USB Stamp adapter board that comes partially assembled. This cost-effective solution is an easy way to interface the FlashFly system to a USB Board of Education, a USB Boe-Bot, or for easy use in breadboarding a Stamp solution. With this board, and a FlashFly Base and Remote Module board, a user can wirelessly program his or her BASIC Stamp and have a means for wirelessly communicating with it. This product is perfect for experimenting with the Stamp in a breadboarding environment.

Features

On-board 5.0V regulator

Status indicator LEDs for power on

Works with FlashFly Remote Module

Key Specifications

Power requirements: 5.0 to 12.0 Vdc (Vin)

Operating temperature: -40 to +185F (-40 to 85 C)

Dimensions: 0.860‖ wide by 1.385‖ long

Kit Contents

BWR-004-101 PCB (1) — SMD components are pre-soldered

12 pin 0.100‖ Headers (2) — Solder to bottom of board

24 pin IC Socket for Stamp (1) — Solder to top of board

8 pin 0.100‖ Female Header (1) — Solder to top of board

Tools Required

Soldering iron (always wear safety glasses when soldering)

Solder (some soldering experience required)

Flux



Assembly Instructions

HINT: When soldering headers or pins, solder one and align the connector so it is perpendicular to the board. If needed, reheat the first soldered pin to realign. Once the connector is straight and perpendicular, securely solder the remaining headers or pins.

Step 1:

Verify the kit contains the following parts, as shown in the photograph to the right.



Step 2:

Install both (2) 12 position 0.100‖ headers into the BOTTOM of the board. Once installed, solder them in place from the TOP of the board.

Step 3:

Install the 24 pin DIP socket on the TOP of the board. Once installed, solder it in place from the BOTTOM of the board.

Install the 8 pin Female Header on the TOP of the board. Once installed, solder it in place from the BOTTOM of the board.

Step 4:

Place the Stamp into the 24 pin DIP socket with the #1 pin of the Stamp toward the 8 position female header.

CAUTION: Do NOT get the USB Stamp adapter board wet. The 24 pin DIP socket from step 3 above is a ―wash away‖ socket. It is designed to have all the clear white portion of it disolve in water leaving only the pins. If by chance the assembly process was not adhered to and the 24 pin DIP socket was soldered onto the board first, prior to the bottom 2 headers from Step 2, then you will need to do the following:

Solder all the remaining pins on the 24 pin DIP socket. Then place your USB Stamp adapter in your dishwasher for a wash cycle. After the white portion in fully disolved and the board is dried, then you can carefully solder the bottom 2 headers in place.



Connecting and Testing

The USB Stamp adapter board has one (1) green LED on the bottom of the board. This LED is illuminated if the power is applied to the Vin pin or the Vdd pin. If 5.0 Vdc is needed for any external circuitry, the available current should be limited to 150 mA on the Vdd pin. If using a Series 1 X-Bee Pro module, usage should be limited to 50 mA.

The supply voltage (6.0 to 12.0 Vdc) can be connected to the Vin pin on the adapter board. If using a regulated 5.0 Vdc power supply, a user can connect it to the Vdd pin on the USB Stamp adapter board. However, in this instance, the Vin pin should not be connected.

CAUTION: The MCP1702 regulator used on Rev A of this adapter board is rated for a 250 mA continuous current. Vdd may be used as a 5.0 V supply output; however, be sure to limit the current use to approximately 150 mA. The rest of the current should be reserved for the FlashFly Remote module to ensure proper operation. If erratic operation occurs in the wireless functions, reduce the current consumption on the 5.0Vdc side (if using it).

Connection Diagrams for USB Stamp Adapter Board

The USB Stamp adapter board is primarily made for use with the FlashFly system to wirelessly download programs. However, the board also allows for an external RS-232 connection.

WARNING

Using an external RS-232 connection will disable the use of the FlashFly in-system downloading capabilities.

In order to connect to an external RS-232 connection, some of the solder pad jumpers (on the back side of the board) will have to be modified using an X-ACTO™ knife. First, cut the trace on SP1, SP2, and SP3 (SP4 is reserved for future use) from the middle pad to the right-side pad. Next, solder a jumper wire from the middle pad of each to the top-left pad. To restore it back for FlashFly operation, do the inverse.
