Transfer file from Raspberry Pi hardware to host computer or MATLAB Drive

Add-On Required: This feature requires the MATLAB Support Package for Raspberry Pi Hardware add-on.



getFile(mypi,source) copies the specified file from the Raspberry Pi® hardware to the MATLAB® Current Folder. Wildcards are supported.


getFile(mypi,source,destination) copies the file to a destination path and optional file name.

You can copy a file, such as .profile, from the Raspberry Pi hardware to the MATLAB Current Folder on your host computer. In MATLAB Online™, the Current Folder is your MATLAB Drive™ folder.


You can use a wildcard to copy any matching file or files from the Raspberry Pi hardware to your host computer. In MATLAB Online, the folder you copy files to is located in your MATLAB Drive folder. You can specify the path of a destination folder. The folder must exist.

Copy the file from /home/pi/ and save it to Desktop.


In MATLAB Online, copy the file from /home/mwuser/ and save it to myfolder in MATLAB Drive.


You can copy a file from the Raspberry Pi hardware to your MATLAB Drive folder when connected to it from MATLAB Online. To use your hardware from MATLAB Online, follow the instructions in Connect to Raspberry Pi Hardware Board in MATLAB Online.

When connected to your hardware from MATLAB Online, the default working directory is /home/matlabrpi, instead of /home/pi. Copy a file from this folder to your MATLAB Drive folder. Your MATLAB Drive folder is the default startup folder in MATLAB Online. View its contents by clicking the Current Folder tab on the left side of the Command Window.


You can also copy files from other folders on your hardware to MATLAB Drive. List the files in /home/pi.

system(mypi,'ls /home/pi')
ans =


Copy cap.jpg from /home/pi to MATLAB Drive.


You can also specify the destination folder in MATLAB Drive. The destination folder must already exist in your MATLAB Drive. Copy myvideo.h264 from /home/matlabrpi to myfolder in MATLAB Drive.


Create a connection from the MATLAB to the Raspberry Pi board. If you encounter errors after running the above command, try using additional arguments (as listed in raspi) or refer to Troubleshoot Connecting Issues to Raspberry Pi Hardware.

mypi = raspi;

Create a connection, mycam, from the MATLAB software to the camera board on the Raspberry Pi hardware, and set the image resolution. The connection displays the camera board properties.

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

Capture and display a sequence of 10 snapshots on your computer.

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

Each of the 10 snapshots is the latest image captured by the camera.

If the image is upside down, change its orientation.

mycam.Rotation = 180

You can use the same approach to change the values of other cameraboard properties.

Record a 60 second video.


Stop the recording immediately.


Copy the video from the board to your computer.


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


Input Arguments

collapse all

Connection to the Raspberry Pi hardware board, specified as a raspi object.

Path and file name on the Raspberry Pi hardware, specified as a string. You can use either the absolute path from the root folder, or the relative path from the present working folder. Use Linux® path and file naming conventions. The default path is /home/pi/. In MATLAB Online, the default path is /home/matlabrpi/.

Example: '.profile'

Example: '/home/pi/.profile'

Example: '/home/pi/.pro*'

Data Types: char

Path and name of file on host computer, specified as a string. If not specified, getFile uses the MATLAB Current Folder and the current file name. Use the naming conventions of the operating system on the host computer. This function does not create new folders. Folders in the path must exist. In MATLAB Online, this path must be located in MATLAB Drive. Optional.

Example: 'C:\Users\myusername\Desktop'
