Illustrated Blog on Embedded Software Architecture
A short definition Pulse-width modulation is commonly used in power-control or motor-control applications. Time is divided into periods. As always, the smaller the time periods, the higher the frequency. Within this time block a pulse signal is applied. The digital signal is logically active (“1”or ON) during a specified percentage of the time period, the […]
Introduction Both ROM and RAM strongly determine the cost of an MCU. And therefor, for an embedded developer, it is important to regard it as valuable resources. Especially for high-volume products (e.g. MCU’s for cars) for which cheap hardware is important, it is crucial to optimize ROM and RAM usage. In this post we assume the […]
In an earlier article, we talked about real-time behaviour, meeting deadlines and how a real-time OS operates. To recapitulate: the highest priority task that becomes runnable pre-empts all other tasks and runs to completion (until it ends, yields or sleeps). Also, we can have different layers of processing. high-to-low priority run-to-completion interrupts run first (all […]
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 […]
