Edouard Lafargue let us republish his demonstration of a Noritake GU140x32-7002 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.
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.
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.
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.
You can preorder assembled Bus Pirate hardware at Seeed Studio for $30, including worldwide shipping.
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.
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.
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.
