WideStudio for BTRON
WideStudio for BTRON is one of WideStudio Suite that enables you to develop a desktop application on T-Engine or BTRON
WideStudio for BTRON offers the following features to develop T-Engine/BTRON applications:
WideStudio for BTRON Environment Settings
WideStudio for BTRON uses Linux or Windows Operating Systems as its development environment for BTRON applicatons. Applications developped on Linux or Windows are transmitted to BTRON to run or for debugging.
Required software are show below:
Also, gcc compiler for BTRON come with bright-v for development kit is required for both Linux / Window.
The rest of description below assumes bright-v development kit installed on /usr/local/brightv (for Linux) and c:/cygwin/usr/local/brightv (for Windows)
Building WideStudio for BTRON (Linux)
As for Linux version, libraries should be built from source codes.
(NOTE)Windows version has BTRON libraries with its package, you don't need to build the libraries.
WideStudio source codes cat be accessed with its filename name ws-vX.XX.X-src.tar.gz on the Internet.
(NOTE)X.XX.X matches the version numbers.
Get that file to expand on Linux box which T-Engine development kit is installed like as following. Tempolary directory can be used for this.
cd /workWideStudio for BTRON building consists of two phases. One is to build WideStudio itself and another is to build BTRON libraries.
cd /work/ws-vX.XX-XAfter completion of WideStudio building, go on to the next; WideStudio for BTRON library building. WideStudio for BTRON library building requires to set path environment variable for BTRON compiler as follows. This is used in generating BTRON binaries.
setenv BD /usr/local/brightv
After set the variable, do:
cd /work/ws-vX.XX-X/srcNo error result in building completion. Let's install WideStudio as follows. (default installation goes /usr/local/ws)
Application Builder Configuration
BTRON complar path should be specified in Application Builder before compling a BTRON application.
Select [Project Setting] from [Project] menu and click on [Environment Settings] Tab to set BTRON compiler path
Creating Hello Application by WideStudio for BTRON
Using a simple application - hello as an example, let's see how BTRON application can be developed by WideStudio for BTRON
First of all, start wsbuilder and create a new project from [New Project] in [Project] menu. Use "hello" as its project name and select [Generic Application]. Project file name is hello.prj
Then, select [Project Setting] from [Project] menu and configure BTRON in TARGET item below in [Basic Setting] tab.
Creating a Window
After that, create a window which will be a base for hello application. Select [New Window] from [File] menu in the builder. Here we select [Generic Window] type with a name "newwin000" and configure the property as follows:
Project name: newwin000On the Window you just created, put a button object and configure its property as follows
Object name: newvbtn_000
Creating an Event Procedure
Next is the most fun time; creating an event procedure. Let's have it say, "Hello!". Using C++ for event procedures, any given program such as an access to an object or data processing can be written here by specifying an event connecting to an object.
For example, if you set mouse-click event on a button, an event procedure aligned with that event runs when you click on the button with mouse.
Chosen a push button; newvbtn_000 that displays "hello!" would have an envent procedure developed as follows. Select "newvbtn_000" and configure it in [New Procedure Create] from [Procedure Edit] in [Edit] menu:
Building Hello Project
After saving the hello project by [Save Project] from [Project] menu in Application Builder, build by [Build All] in [Build] menu. If you successfully complete the build with no error, hello is ready to work.
You will see hello.bz under the project directory after the building. Serial transmit this hello.bz using gterm from BTRON development kit and configure.
Also, you can use fget for Ethernet Transmit to send the file. Please see more details for manuals come with BTRON development kit offered by Personal Media Co.
[/SYS] recv -d /.../hello/hello.bz <- Specify full path for hello.bzNow hello has been registered in a box with a name "Sample Program" You can start this application by double-clicking from a box. The name can be changed by editing hello.f that is created in a box directory
