ECE 471 – Embedded Systems Lecture 8
ECE 471 { Embedded Systems Lecture 8 Vince Weaver http://www.eece.maine.edu/∼vweaver [email protected] 26 September 2013 Announcements • HW#2 is delayed • Read chapter 11 in textbook 1 Brief Overview of the Gumstix Overo Board TODO: Put a diagram here More details after boards are distributed. 2 Coding Directly for the Hardware One way of developing embedded systems is coding to the raw hardware, as you did with the STM Discovery Boards in ECE271. • Compile code • Prepare for upload (hexbin?) • Upload into FLASH • Boots to offset 3 • Setup, flat memory (usually), stack at top, code near bottom, IRQ vectors • Handle Interrupts • Must do I/O directly (no drivers) Although if lucky, can find existing code. 4 Instead, one can use an Operating System 5 Why Use an Operating System? • Provides Layers of Abstraction { Abstract hardware: hide hardware differences. same hardware interface for classes of hardware (things like video cameras, disks, keyboards, etc) despite differing implementation details { Abstract software: with VM get linear address space, same system calls on all systems { Abstraction comes at a cost. Higher overhead, unknown timing 6 • Multi-tasking / Multi-user • Security, permissions (Linus dial out onto /dev/hda) • Common code in kernel and libraries, no need to re- invent 7 What's included with an OS • kernel / drivers { Linux definition • also system libraries { Solaris definition • low-level utils / software / GUI { Windows definition Web Browser included? • Linux usually makes distinction between the OS Kernel and distribution. OSX/Windows usually doesn't. 8 Operating Systems Types • Monolithic kernel { everything in one big address space. -

Initially developed by Android, Inc., which Google backed financially Android (operating system) 2 and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first publicly available smartphone running Android, the HTC Dream, was released on October 22, 2008. The user interface of Android is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Internal hardware such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented. -

Comprehensive Review of the Nokia N810 Internet Tablet
Comprehensive Review of the Nokia N810 Internet Tablet Introduction So what is the Nokia N810? Is it a tablet computer? A PDA? An Internet appliance? An E-Book reader? A MP3 player? A portable video player? Well, it has aspects of all of those devices and more. However, it is marketed as a convenient, wireless, web browsing appliance. As you will soon see, you can do much more than that with it... The entry price was targeted at $479, quite The older N770 on the left next to the new N810 on the right and a bit higher than the debut price of the a dollar bill (for scale). N770 which was $400. Expect the prices to drop, however. The target audience for the Nokia Internet Tablets is people who want to quickly and wirelessly jump on the web to research something or communicate, without having to go to a larger machine or laptop. The N810 extends the convenience of the net in ways no smart phone or PDA ever has. In the Box In the pretty packaging you will find the N810, a very slim battery, a stereo headset with drop (necklace style) mic, a USB cable, a car mount, a tiny charger, a screen wipe cloth, a soft case, a spare stylus, and an instruction poster. Yes, I said “poster”. Unfortunately, they didn't include a real user's manual. There is a manual PDF and help file on the N810, but it would be nice to have a real manual or even a DVD video included. The padded slip-on case is light and will give scratch and shock protection, although it has no hard insert, so there is no crush protection for the screen. -
