Demo: Sure-electronics DE-DP014

July 12, 2010 in Bus Pirate, demonstrations, documentation by Sjaak | 1 comment

To demonstrate some of the new commands from the new firmware 5.2, we interfaced the DE-DP014 from Sure-electronics. This is a single, SPI-like controllable 1.8″ single 5×7 dotmatrix. It has an on-board PIC controller which stores a special ASCII font. The package consist of two units, a simple demo board and two 10-pin cables. Sure provides a decent manual, which is only downloadable from their store.

The DE-DP014 has two 10-pin shrouded headers to provide power, brightness control, data-in, data-out, and clock. The top header is the input and the bottom one the output. Up to 20 units can be daisy chained (according to the manual, we don’t earn enough to buy such an amount!).

Get a Bus Pirate for $30, including worldwide shipping at Seeed Studio. Adafruit also has the Bus Pirate and probe cables in stock and ready to ship.

Demo: Noritake Serial VFD

March 1, 2010 in Bus Pirate, demonstrations by Ian | 2 comments

Edouard Lafargue let us republish his demonstration of a Noritake GU140×32-7002 Serial VFD screen (may prompt about a secure certificate).

The Noritake VFD used here is a “Show and Tell” 140×32 semi-graphical VFD. This display has the big advantage of being able to display graphics and manage so-called ’user windows’, making it a good choice for stepping up from standard text-based LCDs or VFDs towards a more graphical approach.

This tutorial first shows how to interface with the device using async mode, and then how to use a simple python script to display GIF black and white images on the display.

Demo: Parallax RFID reader

February 15, 2010 in Bus Pirate, demonstrations by Ian | No comments

This is an old version, see the latest version on the documentation wiki.

julky demonstrated a USB->serial bridge for the Parallax RFID reader with the Bus Pirate.

The Parallax board reads passive RFID EM4100 type RFID tags, and outputs the tag ID as simple serial data at 2400bps. It’s the first inexpensive RFID reader to catch on with hobbyists.

Demo: is a weekly series that demonstrates devices with the Bus Pirate. Come back next Monday for another new demo.

Demo: KS0074 serial LCD

February 8, 2010 in Bus Pirate, demonstrations by Ian | 3 comments

This is an old version, see the latest version on the documentation wiki.

Sjaak posted this demo of a KS0074 serial LCD in the forum:

I needed to test the SPI library with the newterm branch. I had a nice display from a dead Siemens phone. It uses a KS0074 display (which is an sort of SPI version of the good old HD44780). I found the datasheet and some example code on the internet  (sorry only German is available). During the testing I found out the Bus Pirate spits out the bits the other way around then in the code/datasheet.

Demo: HMC6352 digital compass breakout board

February 1, 2010 in Bus Pirate, demonstrations by Ian | 5 comments

This is an old version, see the latest version on the documentation wiki.

The HMC6352 is a simple compass chip with an I2C interface. If your next unmanned vehicle needs a compass, check out this chip. It has multiple operating modes that balance power use and update frequency. Continuous acquisition provides rapid heading updates, while query acquisitions save power by only measuring only when it’s needed.

Thanks to SparkFun for sending this part to demo. If you don’t want to solder the 24pin lead-less chip yourself, you can get it on a breakout board at SparkFun.

Demo: is a weekly series that demonstrates devices with the Bus Pirate. Come back next Monday for another all new demo.

You can preorder assembled Bus Pirate hardware at Seeed Studio for $30, including worldwide shipping.

Demo: AT45DB041D 4Mbit SPI flash memory

January 25, 2010 in Bus Pirate, demonstrations by Ian | No comments

This is an old version, see the latest version on the documentation wiki.

This demo is what the Bus Pirate is all about. A AT45DB041D 4Mbit flash memory stores the FPGA design on the open source logic analyzer project currently known as SUMP PUMP. We’ve worked with EEPROMs in the past, but this chip is a different beast.

Follow along as we use the Bus Pirate to learn about this chip before writing firmware for the logic analyzer.

Demo is a weekly series that demonstrates chips with the Bus Pirate. Come back next Monday for another all new demo.

Demo: Sure LED matrix

January 18, 2010 in demonstrations by Ian | 4 comments

This is an old version, see the latest version on the documentation wiki.

You may have come across this 16×24 LED matrix board on eBay or at Sure Electronics. Each board has three 8×8 LED blocks and a controller to drive them. A simple three-wire serial interface toggles each LED and configures the overall brightness of the board. Up to four boards can be chained through 2×10 pin headers on the back, a connector cable was included with each board.

We used the Bus Pirate to test the board and learn its protocol before using it with the web platform (more on that later). Grab the datasheet and follow along below.

This is the first of a new weekly series that demonstrates devices with the Bus Pirate. Come back next Monday for another all new demo.
