Launchpad plus LCD equals serial terminal
The Philadelphia, PA based Maker/hacker group Hive76 developed a tiny serial terminal using a TI Launchpad and an HD44780 LCD. The circuit diagram and code libraries are available for download. Some useful work that can be incorporated into larger projects.
NEW PROTOTYPE: USB Universal LCD backpack
The USB Universal LCD backpack controls LCDs with up to 16 interface pins at 3.3volts or 5.0volts. This includes common HD44780 character LCDs and larger graphical LCDs. Small backpack mounts behind most LCDs USB control for common 1×8, 1×16, 2×8, 2×16 … up to 4×40 character displays and some graphic displays 3v3 and 5v LCDs […]
I2C / SPI character LCD backpack
Adafruit has a clever new I2C/SPI LCD backpack based on an MCP23008 IO expander and a 74HC595 IO expander.
PIC LCD backpack with LCD Smartie
This is a prototype of the open source PIC LCD backpack driven by LCD Smartie over a USB virtual serial port. Follow our progress in the development thread.
Soldered prototypes
A big box of PCBs arrived earlier today. Here’s the current progress: 3 PIC USB LCD backpacks, 2 Bus Pirate v4, and a USB POV Toy. Still waiting on a couple parts, but these boards are almost done.
Preview: USB LCD backpack prototypes
Soldered prototypes for the FT232-based USB LCD backpacks. Check out the design on the wiki, and follow development in the forum.
MSP430 low power experiment
Kenneth’s low-power microcontroller experiment tests how long will an MSP430 microcontroller can run on 20F of charged capacitors. Via Hack a Day.
Prototype: Bus Pirate LCD adapter v2
The Bus Pirate LCD adapter v2 enables the mysterious LCD mode on your Bus Pirate. The Bus Pirate can’t control an HD44780 LCD alone, it needs help from a few extra parts. Read the how-to and build your own adapter, or buy it assembled for $9. The v2 adapter is a complete rework of the […]
Week in (p)review: September 12, 2010
Here’s some highlights from the past week, in case you missed them: An EventGhost plugin for the USB IR Toy The final USB LCD backpack design was posted A PIC programming tutorial An updated Bus Pirate v4 design is in the forum for review Software is in development for the LCD backpack Discussion continues on […]
mini USB LCD backpack
This is the mini version of the USB LCD backpack . It has only the IO pins required for the most common HD44780 LCD pinouts. Join the development discussion in the forum. Driver development is under way for LCDsmartie. We’ll be adding support to LCDproc too.
Fragile connectors on the SparkFun Nokia knock-off
Fragile connectors on the SparkFun Nokia knock-off LCD are a headache. They’re not rated for multiple insertions, but we can usually move them very carefully on a final prototype. A mating connector we soldered must have warped from the heat. It ate two LCDs right away. On the right is the ‘good’ from a few […]
Week in (p)review: August 22, 2010
Here’s some highlights from the past week, in case you missed them: Dynamic Sampling depths on the Logic Sniffer! Continued development on an USB LCD backpack and a computer controlled voltage/current source/sink. You’re welcome to get involved too. An updated Bus Blaster design was posted. Bus Pirate v4 was assembled and tested. There are some […]
Week in (p)review: August 1, 2010
Here’s some highlights from the past two weeks, in case you missed them: Bus Pirate firmware v5.4 IR Toy firmware v1.05 with a new sampling mode was released. We also identified the cause of the stuck IR Toy bootloader Dukey added IR Toy support to WinLIRC LCD adapter v2 for the Bus Pirate was tested, […]
Preview: Bus Pirate LCD adapter v2
This is a new LCD adapter for the Bus Pirate. The board has been tested, Seeed is building a manufacturing prototype now. The Bus Pirate LCD library in firmware v5.4+ will require this LCD adapter instead of the old v1 adapter. The v1 LCD adapter was based on a PCF8574 I2C IO expander IC. It […]
#twatch with LCD back in stock
The #twatch is a Twitter scrolling, networked LCD screen. Not into Twitter? That’s ok, that #twatch has a backdoor server that works with a bunch of user submitted scripts and plugins. After a long hiatus, the #twatch with an LCD attached is back in stock at Seeed Studio. There are still a couple #twatch ethernet […]
Demo: KS0074 serial LCD
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 […]
Bus Pirate IC test PCB
A discussion in the forum led to the creation of a new chip demonstration/test PCB for the Bus Pirate. This board has spaces for several commonly-sampled I2C and 1-Wire devices, and an HD44780 LCD tester: I2C 24LC EEPROM (PTH and SMD) TC74 temperature sensor (PTH) DS1085(L)/DS1077(L) frequency generator (SMD) PCF8563/DS1307 real-time clock (PTH) MCP3021 analog […]
Bus Pirate: Nokia 3310 LCD
[vimeo http://vimeo.com/7139826] blue.zener interfaced a Nokia 3310 LCD using the new Bus Pirate binary mode. He also wrote a general Ruby class for the Bus Pirate binmode. There’s a bit more in the forum, too. The step-by-step overview is excellent, great work! Don’t forget that we want your scripts too. We’re giving away two Bus […]
#twatch: backlight control
The #twatch backlight is controlled through a TCP server on port 1337. We use Herculese as our TCP client. Connect to the #twatch TCP server at the IP address shown on the LCD screen. Send the command 0xFE 0x42 0x00 to turn on the backlight. Send the command 0xFE 0x46 to turn it off. Programs […]
