This course aims to help you understand how to choose between different microcontrollers and which one is right for you. It starts with a detailed explanation of a microcontroller and how it compares to a computer. Next a quick summary of the key features you need to consider when choosing a microcontroller will be given. Further the significance of microcontroller architecture when choosing will be explained.You will comprehend the similarities and differences between Harvard Von Neuman CISC and RISK architecture. When you look at the microcontroller it is clear that the role of available software and hardware tools is significant and you will discover which of them pay attention to. The budget is always one of the crucial factors and will be discussed. The course will then give you a detailed explanation of all ten steps when choosing the appropriate microcontroller.To understand which is proper for you you need to explore the microcontroller options available in the market. It will introduce Microchip PIC Atmel AVR Intel 8051 ARM Zilog Z8 and Z80 chips. A detailed comparison between them is also provided. You will also learn about modules and extra boards for microcontrollers. The final section will explore simulation software and free samples.
