Illustrated Blog on Embedded Software Architecture
In this article we are going to give a short overview of mosfets and more specifically power mosfets. Surfing the web, we found this great YouTube video (Developed under Teaching Innovation Project 10-170 of Universidad de Granada in Spain) covering the basics of mosfets: Definition “The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is […]
In part 1, we talked about the ‘contactor’. Relays also use power, and in this particular case, the relay coil could draw up to 2 watts according to its specification. In order to save power, there are a couple of things we can do. Using PWM is one of them. Every relay coil has a […]
The (most obvious?) switching solution would be a high-power relay. In a previous article, we already did an experiment with a Solid State relay (and we will continue to do so). Now we will look further into the ‘contactor’. The ‘kit’ we ordered from www.iacs.co.uk (via Ebay) is a relay board with optical isolation (to […]
Introduction One of the goals of iteration 1 of the energy harvester project is to extend our software platform with drivers for measuring (gpio in, adc), controlling (gpio out, pwm) and debugging (uart). In this article our focus is set on the ADC driver (we already introduced the Analog-to-Digital-Converter here). It is hard (not to say […]
Power with green inspiration. A couple of weeks ago, an electricity blackout in our neighborhood was announced by the power company. We thought this was the ideal time for some experimentation with ‘green’ off-the-shelve products and also explain a bit about the inspiration for the energy harvester project. The various “domain knowledge gathering” experiments (e.g. […]
Introduction Probably one of the most fascinating things you had to do in your early embedded career was controlling some LEDs by means of GPIO (General Purpose I/O). This – of course – is so easy i.e. until your project manager passes by: “I want this LED to blink a little faster” “Why is the […]
This might be a good time to talk about developer (or technical development procedure) facilitators. Although these are not even regarded as intermediate requirements – and certainly are not considered to be as important as user requirements – some development facilitators could be considered as development procedure requirements that have big impact on the process […]
A bottom-up or a top-down approach? In order to be able to try something out, to proof something is technically viable, it is absolutely necessary to do early prototyping and provide ‘POTs’. A Proof Of Technology is just substantiating that there is a potential solution to a technical problem: We must emphasize that it is […]
Introduction A relay – in this context – is an electronic switch and can be controlled by micro-controller logic. There are different types of relays, with different pin configurations. A 4-pin relay can be OFF (not conducting current) or ON (conducting current): 2 pins are powering and thus controlling the relay and the other 2 […]
Introduction The dump load (already introduced here) is used to burn the excess energy of our battery charger. The excess is typically generated by the wind turbine in windy conditions. In contrast with solar energy, the battery charger must accept wind energy in order to protect the wind turbine. For that reason the dump load […]
