@Mikael Kurula:Exhange提交的文件中提供的所有功能现在都是Raspberry Pi硬件的MATLAB支持包的一部分。如果您有matlabr2019a或更高版本，可以使用raspi接口将MA金宝appTLAB代码部署到Raspberry-Pi。查看演示：//www.tatmou.com/help/supportpkg/raspberrypiio/examples.html?category=run-on-hardware&s_tid=CRUX_lftnav_example_connection-to-raspberry-pi-hardware.

In order to be able to deploy the pitch shift example to the rpi, I had to remove ".internal" on line 3 of the file /home/mkurula/MATLAB Add-Ons/Toolboxes/Run on Hardware/+matlab/raspi/AudioCapture.m.

When I tried to deploy the edge detect example to the Raspberry Pi, I got some error message complaining about not finding main.c, and indeed there is no such file where it is supposed to be. The solution is to comment out lines 50-51 and add one line directly after to the file /home/mkurula/MATLAB Add-Ons/Toolboxes/Run on Hardware/runOnHardware.m:
%cfg.CustomInclude = fullfile('codegen','exe',fcnName,'example');
%cfg.CustomSource = fullfile('codegen','exe',fcnName,'examples','main.c');
cfg.GenerateExampleMain = 'GenerateCodeAndCompile';

i am traying to download it but there is something wrong it is hanging so please help me

@Ashwini Patil: targetHardware support starts from R2018a release of MATLAB

hi,i am using R2017b version and i get the error for creating configuration object for hardware
boaed=targetHardware(r,'myApplication')
我收到错误
未定义的函数或变量targetHardware
can i help me solve this problem

The function automatically saves as a log file on the raspberry pi when it needs to be an elf file. Can anyone help me fix this problem?

problem of download

@Afagh: The error message says 'unit8' not 'uint8'. You might have a typo somewhere.

Hello, I am using R2017b version and I get the following error:
runOnHardware（r，'myApplication'）
??? 未定义的函数或变量“unit8”。

==>myApplication行：11列：13中出错
代码生成失败：查看错误报告
Error using codegen

runOnHardware出错（第52行）
codegen（'-config'，cfg，fcnName，'-report'）；

which does not make any sense because I use the uint8 right there in the command prompt and it works perfectly. Would anyone have an idea why this is happening? Thanks in advance for your help.

For R2018a users: use "raspberrypi" object when calling runOnHardware function. That is:

>> r = raspberrypi;
>> runOnHardware(r,'myFunction')

Using "raspi" object results in runOnHardware throwing an error.

@michele benetti: This example requires Embedded Coder license in addition to MATLAB Coder for R2018a and earlier. This dependency was stated in the overview section. I'll update the description accordingly. The error message you are seeing is due to the Embedded Coder requirement.

hi, I have installed the package but when I run
runOnHardware（r，'myApplication'）
I receive as error:
Trial>> runOnHardware(r,'myApplication')

@Ola Olsson: The output of fprintf goes to stdout. In the runOnHardware function, I direct the output to a *.log file. For example, if your M-file is called myApplication.m and you compile and generate code out of it, the output of the application myApplication.elf goes to myApplication.log file. And by default the *.log file is generated in the same directory where you launch the application. So check the *.log file for output.

有一种方法将输出发送到文件r choice. This is illustrated in raspberrypi_motion_sensor_camera.slx. There is a MATLAB function block in this Simulink demo where we save an image to disk. Take a look at that for details.

Really great example. Thanks for providing this! I am about to try to develop a little computer vision tool, and this is a very good start. Now, in that I also want to save some numbers to a text file on disk on the Raspberry Pi, using fprintf. However, it seems that either it does not do anything with it, or it puts the file in place where I am unable to find it. The code generation report is not complaining (as it was when I tried to fprintf an array instead of scalars), so there is no guidance there.

Add your comments on the example and the proposed workflow in the comment section and let us know if you would like to have a more detailed discussion.
