Using ChibiStudio

This documentation will cover the installation of ChibiStudio, ugfx and st-linkV2 for mikromedia STM32F4 board. But, if you use another board/programmer it's should be working with some modifications. For the moment, ChibiStudio is only available for Windows 32 bits. If you want to install it on Linux or OSX please refer to the official site of chibios.

Be careful, if you use Windows 64 bits, you need to install java in 32 bits or ChibiStudio will not start.

Installation

ST-LinkV2

First of all, you need to install the Windows drivers for the programmer.

Download the official STM32 ST-LINK utility form ST web site.

ST use a two page download step. After you have click on the link bellow, a new page is open. Go on the down the page and click on download.

Extract the archive and double click on the file STM32 ST-LINK Utility_v3.6.0.exe.

At the end of the installation, a wizard will ask you to install the drivers (may be the wizard will appear twice). Please install it or you won't be able to transfer a program on the board.

ChibiStudio

Please download the last version of ChibiStudio with the link here : ChibiStudio

For this documentation, we have use the version : ChibiStudio_Preview11.7z

The package is a self-extracted folder that will contain all you need in one folder. Be careful, you need absolutely to extract the file into the root of you C drive.

Then after the extraction you need to have a folder like :

c:\chibistudio

ugfx

For the installation of ugfx, please note that we strongly encourage you to use the git repository. If you have already git installed, download it like this :

• start a git command prompt
• c:
• cd chibistudio
• git clone https://bitbucket.org/Tectu/ugfx.git ugfx

But for this documentation, we will use this direct link.

Extract the content of the archive on the c:\chibbistudio.

You need to extract the contain of the archive in chibistudio folder.

Then after the extraction, you need to have a folder like :

c:\chibistudio\ugfx_release_23_150516

For best practice, and to be easier to remember, rename the folder ugfx. Then after the folder rename you should have :

Congratulation, you have finished the installation process. Now you need to do some customization because the board is not officially supported by chibios.

Configuration

First start of Chibistudio

It's now time to start ChibiStudio. You can find a shortcut in the c:\chibistudio.

If you want, you can copy it to your desktop. Double click on the shortcut. A warning window will open.

Uncheck "Always ask before opening this file" and click the Run button.

ChibiStudio needs java. If you don't installed it before or have Windows 64 bits with java 64 bits, you will see this warning :

Download java and install it.

You don't need to reboot your computer. After install it java, relaunch chibi studio shortcut.

create the first demo project

Close the welcome screen. ChibiStudio is provided with two workspace. One for the chibios 3 unstable and one for chibios 2. As the version 3 is not stable you need to switch to version 2. To do it, go the the file menu, switch workspace and select c:\chibistudio\workspace26.

To start a new project the faster way, you can copy one of the demo you will find in the project explorer. You can selection any project, but to be sure, please use STM32F4xx-GPT. Double click on it to open it. Then right click on the folder icon of this project and select copy. To copy it, right click on the icon and select past. A new window appear name the new project MikroMedia base and click ok.

New we need to copy some files from the ugfx folder. Open Windows explorer and go to C:\ChibiStudio\ugfx\boards\base\Mikromedia-STM32-M4-ILI9341\example_chibios_2.x. You need to copy all files and folder form this to your new project.

Copy C:\ChibiStudio\ugfx\boards\base\Mikromedia-STM32-M4-ILI9341\example_chibios_2.x\*.* to C:\ChibiStudio\workspace26\MikroMedia demo. Replace all files. For this tutorial, you will use demo software of ugfx. All demo program has already a main function. You can delete the main.c of the new project folder.

On ChibiStudio, open you new project and edit the Makefile. You need to change the path of chibios and ugfx like :

GFXLIB					= ../../uGFX
CHIBIOS				= ../../ChibiOS

That the end. You can try to compile you demo. This will compile the gdisp basics demo as the line says :

GFXDEMO					= modules/gdisp/basics

To compile, click on the hammer icon.

If you have the error below, then you haven't save you Makefile. save it and try again.
