SMART COMBINATIONS
Complexity is what you get out of a project, not what you put into it. Each hardware module connects to some other module via one of the busses, and each software module performs its task. It’s when you put all of these together to perform coordinated tasks that it appears to be doing something complex. This project is an example of this. The MP3 decoder module is fairly simple, but when you coordinate it with the TCP module, alarm module, and GUI, you get an MP3 alarm clock. Each peripheral in the PIC24FJ64 is simple by itself, but by combining them you get a complex set of functionality in a simple package.
Having the ability to choose PIC24FJ64 peripherals and the pins they’re assigned to—combined with a new era in EDA tools and services and software development tools—will enable you to create interesting projects with little investment other than your own time.
