CHAPTER 1: OVERVIEW

1. Introduction to the chapter

Thank you for choosing the MOD-VGA video shield from Olimex! This document provides a user’s guide for the Olimex MOD-VGA. As an overview, this chapter gives the scope of this document and lists the board’s features. The document’s organization is then detailed.

The MOD-VGA development board enables code development of applications running on the FPGA from the SPARTAN-3A family, manufactured by XLINIX.

MOD-VGA is an open-source, open-hardware project and all documentation is available to the customer. It is tested and working with OLIMEX AVR boards.

1.1 Features

MOD-VGA is a game adapter for the Arduino – or anything else with an SPI interface – built as a single shield that stacks up on top of the Arduino and has plugs for a VGA monitor and stereo speakers. The board is based on the open-source, open-hardware GAMEDUINO project by excamera. For more information on the original project please visit

http://excamera.com/sphinx/gameduino/.

1.2 Target market and purpose of the board

The board follows the Arduino shield connector platform and can be mounted directly on 3.3V Arduino boards. Note that if your Arduno board doesn't have 3.3V operating mode you would need level shifter. The board comes with examples and libraries compatible with Arduino IDE (after importing the library and the examples provided on our web-site in Arduino).

The board is tested and working with our OLIMEXINO-328:

https://www.olimex.com/Products/Duino/AVR/OLIMEXINO-328/open-source-hardware.

The board has hardware compatibility with any 3.3V Arduino-like board and also Maple boards, Duinomite boards, and basically every board that follows the Arduino shield connector platform and can operate at 3.3V. However, the software support for all boards except for the Arduino-compatible AVR ones is not still implemented and might require extended software knowledge to be implemented.

Customers have full access to the technical documentation of the board. The software is released under General Purpose License and the board is considered open-hardware.

CHAPTER 2: SETTING UP THE MOD-VGA BOARD

2. Introduction to the chapter

This section helps you set up the MOD-VGA development board for the first time. Please consider first the electrostatic warning to avoid damaging the board, then discover the hardware and software required to operate the board.

The procedure to power up the board is given, and a description of the default board behavior is detailed.

2.1 Electrostatic warning

MOD-VGA is shipped in a protective anti-static package. The board must not be exposed to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the component pins or any other metallic element.

2.3 Requirements

In order to set up the MOD-VGA optimally, the following items are required (separated in hardware and software requirements).

Hardware:

- Host board with Arduino platform connectors (For example OLIMEXINO-328 or OLIMEXINIO32U4) that can operate at 3.3V (or level shifter)

- VGA monitor

- PS2 keyboard (that can operate at 5V or 3V)

- Audio output device

Software:

- Arduino-IDE

- A library that needs to be imported in Arduino-IDE and can be found at our web-site at MODVGA's page

Page 7 of 23

2.4 Powering the board

The board gets powered when mounted on compatible Arduino board by 3.3V.

Important: MOD-VGA is not 5V tolerant.

The SPI lines coming from the main board go to the XYLNIX SPARTAN-3A chip via 47 Ohm resistors and the GPIO pins of SPARTAN-3A have an absolute maximum of 4.6V!

2.5 Running an example using Olimex OLIMEXINO-328

First place properly the library for Arduino that can be found on the device's web page:

https://www.olimex.com/Products/Modules/Interface/MOD-VGA/

Make sure that the OLIMEXINO-328 board operates at 3.3V! There is a switch that modifies the operating voltage of the board – either 3.3V or 5V operation.

Then start Arduino and open the corresponding to OLIMEXINO-328 board configuration:

Tools -> Board -> Arduino Duemilanove w\ATmega 328

Then program for example:

Files -> Examples -> Gameduino -> Audio -> player

We should see a graphic and there should be sound (if we have audio output device connected).

6.6 Keyboard connector

The key board connector is a standard PS2 one requiring MINI-DIN cable connector. By default it operates at 5V. The voltage available for the keyobard can be changed by modifying jumper 5V/3V.

6.7 Jumper description

Please note that both jumpers on the board are SMT type. If you feel insecure of your soldering/cutting technique it is better not to try to adjust the jumpers.

6.7.1 5V/3V

Those jumpers control the voltage available at the PS2 keyboard connector.

The default position is 5V.

6.7.2 SJ1

SJ1 jumper controls whether SPI SSEL line that is available on the UEXT pin #10 is also connected to pin D9 from the digital connector of the Arduino interface. If the jumper is connected then the mentioned multiplexing is present.

The default position is closed (SPI CS is available simultaneously at pin #10 of the UEXT connector and at pin D9 from the Arduino shield connector).

9.4 Product support

For product support, hardware information and error reports mail to: support@olimex.com. All document or hardware feedback is welcome. Note that we are primarily a hardware company and our software support is limited. Please consider reading the paragraph below about the warranty of Olimex products.

All goods are checked before they are sent out. In the unlikely event that goods are faulty, they must be returned, to OLIMEX at the address listed on your order invoice.

OLIMEX will not accept goods that have clearly been used more than the amount needed to

evaluate their functionality.

If the goods are found to be in working condition, and the lack of functionality is a result of

lack of knowledge on the customers part, no refund will be made, but the goods will be returned

to the user at their expense.

All returns must be authorized by an RMA Number. Email support@olimex.com for authorization

number before shipping back any merchandise. Please include your name, phone number and order

number in your email request.

Returns for any unaffected development board, programmer, tools, and cables permitted within 7

days from the date of receipt of merchandise. After such time, all sales are considered final.

Returns of incorrect ordered items are allowed subject to a 10% restocking fee. What is

unaffected? If you hooked it to power, you affected it. To be clear, this includes items that

have been soldered to, or have had their firmware changed. Because of the nature of the

products we deal with (prototyping electronic tools) we cannot allow returns of items that have

been programmed, powered up, or otherwise changed post shipment from our warehouse.

All returned merchandise must be in its original mint and clean condition. Returns on damaged,

scratched, programmed, burnt, or otherwise 'played with' merchandise will not be accepted.

All returns must include all the factory accessories which come with the item. This includes

any In-Circuit-Serial-Programming cables, anti-static packing, boxes, etc.

With your return, enclose your PO#. Also include a brief letter of explanation of why the

merchandise is being returned and state your request for either a refund or an exchange.

Include the authorization number on this letter, and on the outside of the shipping box.

Please note: It is your responsibility to ensure that returned goods reach us. Please use a

reliable form of shipping. If we do not receive your package we will not be held liable.

Shipping and handling charges are not refundable. We are not responsible for any shipping

charges of merchandise being returned to us or returning working items to you.
