Use of C-code for a RaspberryPi Device-Integration

Question

Hi,

As a beginner of Embedded Wizard, I am trying to create a user interface from which you can run, read, write data in a .c file. I want to communicate from EW to a Raspberry pi 3, and vice versa. In a first time I just want for example to print a HelloWorld in the Raspberry terminal or change EW Text content, but for a further application I would integrate some voice recognition. I already looked at the Device Integrations articles and some previous questions but it doesn't seems clear to me on a few points :

• Which blocks do I need for this ? (Is there a generic template to repeat ?)
• In a Device method block ,are they precise code lines/keywords to run/write/read a file ?
• How can I "link" a .c file to EW ? (Where do I put the file ? or a command so EW can locate it)

Thanks in advance for your help and advice.

Hello,

have you seen the example "Device Integration" that is provided within the set of examples in the Build Environment for Raspberry Pi 3? It is located in the subdirectory /Examples/DeviceIntegration and shows the basics about starting a certain action from the GUI and updating the GUI from the underlying system. It is intended to serve as template for your own developments.

You own C files have to be added to the makefile in order to compile them together with the GUI application and other software packages. There is no need (or possibility) to put C code into an Embedded Wizard Studio.

I hope this helps...

Best regards,

Manfred.
