Title page
Hello, everyone! I'm Sacha Chua, and I'm here to talk about embedded
system design from the developer's point of view.
What _is_ embedded computing, anyway? It helps to define it in
contrast to personal computers, which we're all familiar with.
PC/embedded system comparison
General use
Personal computers are intended for general use. They can run a wide
range of applications - games, business apps, that sort of thing.
Specific function
Embedded systems, on the other hand, are typically designed for a
single purpose. Think of a calculator, for example, or the logic in
vending machines. (Of course, some embedded systems are becoming more
general now, like personal digital assistants a).
OS, apps
Personal computers
System
Keyboard/mouse/monitor
On PCs, you can usually assume that someone
Different input/output
Easy to dev or change programs
Infrequently updated
Challenges
User needs / expectations
Although crashes and data loss seem to be part of our everyday
computing experience, people expect embedded systems to be reliable.
Imagine an embedded system that crashes! What if your phone crashed
and had to be rebooted all the time? People expect features,
reliability, and all for a low price.
Tight space and memory constraints
Development tools
Development process
One of the things about embedded development is that the process is a
little bit longer. It's not the usual edit, compile, run cycle. It's
edit, compile, burn to flash, run.
Architectural quirks
And of course if you go into embedded development, you'll probably
have to deal with different architectures. For example, you'll learn
about the quirks of conditional ARM.
Why go into embedded dev't?
It's fun!
It's challenging!
It's useful!
How to get started
Courses on computer interfacing / hardware / digital logic
Experiments
Internship / work / open source
What you need: software, hardware, patience
