ECE597 Project Adding Sense to Beagle

2010-04-20T20:22:48Z

Jiangq:

== Description of Project ==
Sensory aware applications are becoming more mainstream with the release of the Apple iPhone. This project would combine both HW and SW to add sensory awareness to beagle. First, additional modules such as GPS, 3-axis accelerometers, gyroscopes, temperature sensors, humidity sensors, pressure sensors, etc, would be added to Beagle to compliment the microphone input in order to allow sensing of the real world environment. Then software APIs would need to be layered on top to allow easy access to the sensory data for use by applications.

[[User:Jesionaj | Adam Jesionowski]]

== Timeline ==
Week 3: Get accelerometer 
Week 4: Hook up sensor to the I2C; See what Beagleboard does automatically with I2C. 
Week 5: Learn how ARM I2C C functions work; Start coding. 
Week 6: Finish coding. 
Week 7: Do documentation. 
Week 8: If we are on time, start working on another I2C sensor. 
Week 9/10: Padding time.

== Milestones ==
• Read data from I2C line. 
• Call our library from another C program. 
• Create clear documentation.

Cleaning targets:
clean - Remove most generated files but keep the config and
enough build support to build external modules
mrproper - Remove all generated files + config + various backup files
distclean - mrproper + remove editor backup and patch files

Configuration targets:
config - Update current config utilising a line-oriented program
menuconfig - Update current config utilising a menu based program
xconfig - Update current config utilising a QT based front-end
gconfig - Update current config utilising a GTK based front-end
oldconfig - Update current config utilising a provided .config as base
localmodconfig - Update current config disabling modules not loaded
localyesconfig - Update current config converting local mods to core
silentoldconfig - Same as oldconfig, but quietly, additionally update deps
randconfig - New config with random answer to all options
defconfig - New config with default answer to all options
allmodconfig - New config selecting modules when possible
allyesconfig - New config where all options are accepted with yes
allnoconfig - New config where all options are answered with no

Other generic targets:

(default: /home/qiang/Desktop/linux-2.6/usr)

Static analysers
checkstack - Generate a list of stack hogs
namespacecheck - Name space analysis on compiled kernel
versioncheck - Sanity check on version.h usage
includecheck - Check for duplicate included header files
export_report - List the usages of all exported symbols

htmldocs - HTML
pdfdocs - PDF
psdocs - Postscript
xmldocs - XML DocBook
mandocs - man pages
installmandocs - install man pages generated by mandocs
cleandocs - clean all generated DocBook files

Architecture specific targets (x86):

install - Install kernel using
(your) ~/bin/installkernel or
(distribution) /sbin/installkernel or
install to $(INSTALL_PATH) and run lilo
fdimage - Create 1.4MB boot floppy image (arch/x86/boot/fdimage)

FDARGS="..." arguments for the booted kernel
FDINITRD=file initrd for the booted kernel

i386_defconfig - Build for i386
x86_64_defconfig - Build for x86_64

make V=0|1 [targets] 0 => quiet build (default), 1 => verbose build
make V=2 [targets] 2 => give reason for rebuild of target
make O=dir [targets] Locate all output files in "dir", including .config
make C=1 [targets] Check all c source with $CHECK (sparse by default)
make C=2 [targets] Force check of all c source with $CHECK

Execute "make" or "make all" to build all targets marked with [*]

Jiangq:

Here is a wiki you can practice editing. Before you can edit it you will have to create an login. Pick something that will make it easy for me to identify you as part of my class. Then just add your name and date on the end of the table.

You can get help here: [[Help:Contents]].

If you need help with syntax check out the [[Editing Quickstart Guide|eLinux guide]] or the [http://en.wikipedia.org/wiki/Wikipedia:Cheatsheet Wikipedia Cheetsheet].
