Overview
--------

The goal of the CMUcam project is to provide simple vision capabilities to small
embedded systems in the form of an intelligent sensor. The CMUcam3 extends upon
this idea by providing a flexible and easy to use open source development
environment that complements a low cost hardware platform. The CMUcam3 is an
ARM7TDMI based fully programmable embedded computer vision sensor. The main
processor is the
`NXP LPC2106 <https://www.nxp.com/docs/en/data-sheet/LPC2104_2105_2106.pdf>`__
connected
to an Omnivision CMOS camera sensor module. Custom C code can be developed for
the CMUcam3 using a port of the GNU toolchain along with a set of open source
libraries and example programs. Executables can be built and flashed onto the
board using the serial port with no external downloading hardware required.
