1.2 Development platform spirit

The EVALKITSTKNX has been developed in the spirit of the STM32Nucleo boards.

Expansion boards with additional functionality can be plugged directly on top of the

Eval Kit development board or stacked on another expansion board.

2 Software overview and setup

2.1 Software components

The EVALKITSTKNX comes with a complete software package. A sample application

is provided.

Access to hardware features is simplified with the utilization of the STM32 Standard

Peripheral Libraries (SPL)

A demonstration version of the TAPKO's KNX protocol stack is provided as a binary

file.

The software package is compatible with two free GCC-based IDEs: Ac6 System

Workbench for the STM32 and Atollic TrueSTUDIO®. Versions of these two IDEs

exist for the Linux®and Windows OS.

2.2 Software overview

STM32F103RB-STKNX software description

This software, running on the STM32F103, demonstrates the STKNX capabilities.

It is built on the top of the STM32 Standard Peripheral Libraries (SPL) that eases

access to STM32 features.

It uses a demonstration version of the TAPKO KNX protocol stack.

Example to demonstrate actuator and sensor.

UM2409 Software overview and setup

2.4 Install and build firmware with Ac6 System Workbench

1. Download the STM32F103RB-STKNX package and extract it in your file system.

Open the AC6 System Workbench for the STM32 and when requested to select a directory

as workspace, browse to:

<your path>/STM32F103RB-STKNX/Project/STM32F10x_STKNX_LedLevel/SW4STM32

Figure 6. Workspace selection

2. In the Project Explorer panel, right click and select Import General “Existing

Projects into Workspace”.

UM2409 Software overview and setup

5. Select the project name in the Project Explorer, and click on the Clean icon or

select Clean Project in the contextual menu.

6. Click on the build icon or select Clean Project in the contextual menu.

Figure 10. Console view

7. Once build is finished, you can start debugging the project click on the Clean icon

or select Debug As Embedded C/C++ Application in the contextual menu.

Or you can drag and drop the binary (EvalKitSTKNX_LedLevel.bin), available in

Debug, to the virtual drive that is mounted when you connect the EVALKITSTKNX

board to your computer. The name of this virtual drive is STKNX.
