Wxwidget serial
For people like me with not so much experience with windows programming it is a difficult feat to achieve especially the receiving data part sending data is comparatively easier.
But still i was not able to receive data. I wrote this program for an embedded systems project i did " Bluetooth based home automation ". In this project, by sending certain characters to the device using serial port i could turn on or off household electrical appliances connected to it.
But recently i figured it out how to write a simple totally basic command line program to send and receive data from serial port. I built the GUI part using wxWidgets had to mess around a lot first to get the wxWidgets to work at beginning and used the same C code used in the console app to deal with the UART interfacing part. Well it has a few bugs but i consider it not bad for beginners like me.
Below you can find the complete code for the command lin e program. You can compile it using any free version of Visual Studio or using mingW. You can use Codeblocks also it comes with a pre-configured version of mingW.
We hope that relatively few people will be negatively affected by this, but for those who are, please post your bug reports to our mailing lists instead. And please also use the mailing lists to let us know if you encounter any problems after this migration! A quick overview of the recent changes and improvements in wxWidgets: since 3. But now you can also easily provide your own high resolution version to avoid the bitmaps in your application looking blurry in high DPI.
This already works today with wxButton and all the derived classes , wxStaticBitmap and wxToolBar and all the other classes using bitmaps will support the new API in wx 3. The next big addition to the API is the wxUILocale class , which provides a new and more flexible way to get locale-specific information than the old wxLocale. But first we have to some things to spaciate and organize the layout.
First add a wxBoxSizer. Sizers make the job of organize the elements in the screen for us. Then add a wxPanel inside the BoxSizer. Now add a wxGridSizer inside the panel. For more references about doing this you can see the article referenced before.
The wxGridSizer let us add elements in a matrix instead in a line as in the BoxSizer. If you select the GridSizer from the left resources tree you will see its properties in the properties menu below the tree. In the GridSizer properties you can set the row and column number.
For simplicity I made the received field in only one line, buut is easy to make it multiline setting the correct propertie in the textfield properties. Once we have this set of sizers in the screen we will proceed to build the screen. The goal screen is this:. Now we have to add the objects. That is doing by clicking on the object in the object bar and then clicking on the diagram. First click on the wxComboBox icon in the Standar bar and then click in the little square that we have as our screen.
Now we have the future COM ports list. Clicking on it and in the properties list in the left we can see some attributes we can change. The principal attribute to change is the object name so we can refer to it and make the code more maintenable. Then add the button on the right of the comboBox, change it's Var Name to conBut and the label to Connect. Now add a wxTextCtrl.
Add another wxButton. Finally add a wxTextCtrl. We will define it as read only setting this propertie in the style option in the propertie editor:. Remember that later when we define the functions to interact with the elements in the screen, that functions will be referenced to the var name of the objects.
Now you can build the project to see if it is working. If every thing is ok we have something like this:. Thank everybody a lot and again I really appreciate every single hint!
