Jechavarria wrote a post on his blog detailing how to interface 8 LCD displays and 24 leds with only two wires: A couple of weeks ago, I just post a review of my MCP23017 breakout board. As the board configuration … Read more
Jechavarria has designed this breakout board with the MCP23017 I2C IO expander: With this board you can drive a 2×16 display LCD with only two signals (I2C). I also develop some code (in C) to manage this device, based on … Read more
Alex received a monochrome 256×128 LCD with a missing controller chip. The board features 8 Hitachi LCD drivers, but without the controller you have to drive the display by constantly sending data to refresh the picture. After some research he … Read more
Alex connected up an salvaged laptop LCD to his Papilio Plus FPGA development board. He is designing a pair of boards for easier interface, one is designed as a wing for the dev board, and the other as a breakout … Read more
As a follow up to the “One wire control of HD44780 LCDs” post, McLaren shared the Assembly source code for his project. Pick up the source in the forum. Assembly language source file and hex file (for 12F683) attached… Allow … Read more
Pretty user interfaces with a PIC 32: As the demand for Graphical Embedded Applications becomes more popular, so does the need for developing cost effective solutions. Many companies today offer solutions involving an additional internal or external graphics controller as … Read more
EEVblog brought up the Bus Pirate LCD adapter this week, so we though it was a good time to talk about the latest v3 hardware revision and do a simple demo. This is a small board that has everything needed … Read more
Lars designed and produced these LCD touch and button Boosterpacks for the MSP430. It’s an LCD breakout with 4 tactile buttons or 4 cap buttons, depending on the version. It sits on top of the 430 LaunchPad, but can also … Read more
A while ago we wrote about using cheap Nokia 1202 LCDs for projects. These LCDs come with a solderable connector, and are easy to interface over the I2C bus. Toxic239 made a frequency counter based on the MSP430 Launchpad and … Read more
Ezflyr’s GPS-based clock uses the GlobalSat EM-406 module to show the time with around 1 second accuracy. Here is a photo of the completed GPS Display Time Standard I intend to use for setting a variety of clock projects I’ve … Read more
Abdullah explored the idea of driving two character LCDs in parallel. When he couldn’t find any information about this online, he decided to try it out himself. Then I thought about it and I gave it a go. The result … Read more
Kerry uses a DIY serial display to show debugging data sent from an Arduino’s UART. Sometimes the data comes too fast to read, so he added a 4K buffer and controls to scroll thorough the history. …if your application generates … Read more
Mick received his boards for the AVR transistor tester (machine translation) and was quick to assemble them. His board was designed to the exact dimensions of a 2X16 LCD screen. He did have some issues with the silk screen, but … Read more
We got our hands on a few cheap 2×16 red/black LCDs of eBay for $5 a piece, these are the same LCDs from the unboxing video. In preparation to build the soldering iron driver, we tested them out with the … Read more
