Drive an old laptop display from an AVR

Jean refers us to this article by Eric Wazhung  about interfacing LVDS displays using an 8-bit AVR: Different displays have different (undocumented) functionality. With the several I’ve tested, I’ve attempted to create a step-by-step procedure to get a new display going (or find out early-on if it’s not possible. So far I haven’t run into one that […]

Interfacing Adafruit 7-segment Backpack with Bus Pirate

asd has written an article on interfacing Adafruit 7-segment Backpack with Bus Pirate Bus pirate doesn’t do much by itself but needs some accompanying chip talk to. I got my hands on 7-segment display from Adafruit which has HT16K33 controller on it. HT16K33 chip is accessed via i2c protocol so it is good candidate to learn […]

Interfacing an I2C GPIO expander (MCP23017) to the Raspberry Pi using C++ (SYSFS)

Hertaville posted a detailed tutorial on interfacing the MCP23017 to the Raspberry Pi using C++ (SYSFS): In this blog entry I will demonstrate how to successfully interface the MCP23017 general purpose input/output (GPIO) expander from Microchip, to the Raspberry Pi over the I2C bus.

Amarino: Android meets Arduino

Several recent posts have dealt with the topic of interfacing Arduino with devices using the Android operating system. Here’s another approach: Amarino. “Android meets Arduino” is a toolkit, basically consisting of an Android application and an Arduino library which will help you to interface with your phone in a new dimension. You can build your […]
