||The Technical University of Denmark is currently developing a student satellite,
DTUsat-2. The satellite is to carry a student developed camera, PicoCam,
designed for use in space. Up until now, the control software developed for
DTUsat-2 has lacked a camera interface for handling communication with
PicoCam, which lives up the current infrastructure of the onboard software.
Requirements for such an interface are analysed in the current DTUsat-2
context. From this analysis a design is presented which form the basis of development.
To ensure reliable operation a series of tests have been conducted.
The result is a Camera Module handling both predefined camera operations,
including saving images to Flash memory, while also being able carry out a
user defined sequence of camera commands and the ability to send a raw byte
sequences to the camera. During the project an extra effort has been made to
extend the satellite software with a testing environment. Besides this, has a
new packet interface, for inter module communication, been used for the first
