Delete File on Raspberry Pi Hardware

You can delete a file on the Raspberry Pi™ hardware.


Delete Multiple Files on Raspberry Pi Hardware

You can delete multiple files on the Raspberry Pi hardware using a wildcard character, *.


Use the Camera Board

You can create a connection to the Camera Board, take a photograph, and record video.

Create a connection to the Raspberry Pi board.

mypi = raspi;

Create a connection to the Camera Board while changing the resolution, and assign that connection to a handle, mycam. The handle displays the Camera Board properties.

mycam = cameraboard(mypi,'Resolution','1280x720')
mycam =

Import and display a sequence of ten snapshots on your host computer.

for ii = 1:10
img = snapshot(mycam);

If the image is upside down, change the orientation of the image.

mycam.Rotation = 180;

You can use the same approach to change the values of many mycamera properties listed in the "Name-Value Pair Arguments" for cameraboard.

Record a 60 second video.


Stop recording before the 60 seconds have elapsed.


Copy the video from the board to your host computer.


Delete the video file from the board to free up space.
