Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi

At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more.  Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features. The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:

So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and […]

Board Bringup: You, Me, and I2C – ELCE 2012

David Anders, embedded systems developer at Texas Instruments, explains how to work with I2C in Linux based embedded systems at ELCE 2012. Abstract: Board bring up is one of the most under documented aspects of embedded development. I2C is such a powerful, low-cost, and ubiquitous method of communication, that a basic understanding of it’s usage is essential to the embedded linux developer to quickly bring up and debug embedded designs. This presentation will look at the various software and hardware aspects of working with I2C using simple case studies highlighting the implementation of an EEPROM and a GPIO Expander. Most embedded Linux developers at some point in their career will be handed a piece of hardware that is untested. This presentation intends to provide some information about core tools and methods for bring up of I2C interfaces and assorted I2C based peripheral devices. David Anders has previously presented at Embedded […]
