Revision as of 04:02, 21 May 2010


I am currently a Graduate student at Rose-Hulman Institute of Technology pursuing my MECE (Masters of Electrical and Computer Enginnering) degree. My undergraduate degree was in Computer Engineering, also from Rose-Hulman. I am the Public Relations officer of the Rose-Hulman Linux Users' Group. I am working on another project using the BeagleBoard to control a walking four legged robot.

Contributions

Most of my work is with the BeagleBoard hardware. I helped with pages on PWM on the BeagleBoard and I2C on the BeagleBoard. I created the page on Interfacing with the BeagleBoard hardware. This page contains a variety of information on how to make a board to interface with the BeagleBoard, including dealing with power and level shifting.

  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 [*]

          The ARM series is a line of low-power-consumption RISC chip designs
          licensed by ARM Ltd and targeted at embedded applications and
          handhelds such as the Compaq IPAQ.  ARM-based PCs are no longer
          manufactured, but legacy ARM-based PC hardware remains popular in
          Europe.  There is an ARM Linux project with a web page at
          <http://www.arm.linux.org.uk/>.
