In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers. The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later. Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.

De werking van veruit de meeste moderne elektronische apparaten is niet slechts op één enkel principe gebaseerd. Vaak staat een of andere computer (doorgaans een microcontroller) centraal. Uit deze fundamentele opzet – een computer die is ingebed in een bepaalde toepassingsschakeling – is de algemene benaming Embedded Systems voortgekomen. De meeste van deze systemen moeten vanuit het niets worden ontwikkeld, en daarbij komt het op elk detail aan. Vindingrijkheid en veelzijdigheid zijn dan een vereiste. De problemen die opgelost moeten worden, vormen niet zelden een ware uitdaging en betreffen niet alleen de analoge en digitale elektronica maar ook de systeemarchitectuur, programmering en programma-organisatie. De delen van deze reeks zijn geschreven voor iedereen – leerling, student of beginnend elektronicus – die zich terdege wil bekwamen in de professionele hardware- en systeemontwikkeling. En ze richten zich tot de allround-elektronicus die geen tijd heeft om specialist op een van de vele deelgebieden te worden maar die weet dat hij met standaard huis-, tuin- en keukenoplossingen niet ver komt. Ze bieden wat studenten en professionele elektronici nodig hebben: een opfrissing en verdieping van de basiskennis, een bron van inspiratie en een schat aan details en spitsvondigheden. Dit deel behandelt de passieve componenten: vaste weerstanden instelbare weerstanden NTC- en PTC-weerstanden spanningsafhankelijke weerstanden condensatoren spoelen transformatoren contactelementen
