A need popped up at work for a data logger for various lab tasks. Quickly looking at the market, I failed to identify a lab tool for data logging (cheap, easy but powerful setup, remote access); something for researchers and scientists. I decided a Raspberry Pi with some input buffering would be ideal for the […]
Following on from adding support to wiringPi for the MCP4725 DAC, I wanted to add driver blocks to Simulink such that one could use them to create graphical models for the Raspberry Pi that could interface with the real-world – a workable alternative to expensive real-time targets.
The Raspberry Pi lacks a DAC but using the I2C bus, one can easily add a device like the 12bit MCP4725. The GPIO library wiringPi provides support for I2C devices, however, getting the MCP4725 working with it isn’t a simple as one might hope. The device is 12bit but the I2C protocol works on bytes […]
Simulink Embedded Coder offers an ARM Cortex-M support toolbox, which includes code optimisation for the MCU and QEMU emulation but lacks any S-Block drivers for the device. The lack of drivers limits the Simulink development to merely number crunching. You can create cevel blocks that execute external C functions but this requires separate source files […]
The Atmel Studio IDE is a useful tool thanks to the comprehensive debugging support and management of project drivers via the Atmel Software Framework (ASF) – coming from a hardcore Vim advocate. One thing I dislike about IDEs is the fact they hide the make process from the user making it difficult to break a […]
Since setting up an boblight on my RaspBMC, I’ve been wanting a nice gui to manage it; turn it on and off, change colours. I was going to make a plugin to improve my Python knowledge but decided a web plugin would be more flexible as it would be controllable from any device. Using Chris […]
When I first started seeing the Ambilight (Philips’s lighting system that allows the display to bleed out) clones popping up I knew I wanted to create one myself. The open-source system has been fairly well refined to this point, such that it is pretty much plug and play with Raspbmc (XBMC for the Raspberry Pi). […]
My last AirPi post has been popular – and still is – but part of why of like Arch linux is that it is constantly updating so you must be hands on, learning a new part of the OS the hard way! Since my post a year ago, Shairport has some new features and dependencies, […]
I’ve had a BootCamp partition on my Macbook since it bought it; I waited specifically for the Intel CoreDuo Macbooks. Sometimes I don’t want to restart just to run an app or test something out, so developed this bash script to boot it using Virtual Box.
Why Replace My 2006 MacBook HDD with SSD My MacBook is the 2006 original; the white Core Duo 32bit. I got it upon starting University and that ended up taking six years. Amazingly, it is still going strong and whilst I want a nice retina MBP, it would be truly frivolous, given how well this […]
