A Basic Approach to Designing Embedded Systems Using a Simple Calculator and C Programming Language

F Tanshi, N Bello

Abstract


Embedded systems form the bedrock of most consumer appliances in today’s world. Products such as automatic transmission cars, fuel pump metres, washing machines, digital cameras, DVDs, mobile phones, vending machines e.t.c depend on an embedded microcomputer to enable it perform its range of functions. For example a vending machine may have three main functions (namely - insert money, choose item to be purchased and send out item to buyer/user) that are controlled by an embedded chip through its peripherals which are linked to the appliance’s user interface. This paper intends to be a complete introductory guide to embedded design considering a simple calculator that uses a microcontroller for input, processing and output operations.
