OpenWSN support

The OpenMoteSTM is fully supported in OpenWSN.

The OpenWSN builders build the OpenMoteSTM firmware nightly:

The OpenMoteSTM Motes is designed by Micro-architecture and Integrated Circuit Lab (MICL) the University of Science & Technology in Beijing.

XBee pin compatibility

20 Pins are left to fit with the definition of XBee's 20 Pin. Since XBee is widely used for wireless communication, the compatible pins make OpenMoteSTM to use the external boards for XBee, which existed for many kinds of, as well.

Tools

Debugging

We use J-Link as our JTAG debugger tool to debugging OpenMoteSTM. It is used when downloading or debugging applications running on OpenMoteSTM.

J-Link

JTAG-Adapter

A JTAG-adapter is needed to adapt the jtag port on OpenMoteSTM. We use J-Link 9-pin Cortex-M Adapter.

USB Cable

When developing OpenMoteSTM's serial Port, you need a Micro-B USB cable to connect the mote to a PC.

How to Download

We suppose you have gathered all stuff listed above. Besides, you are also required to install IAR for ARM (version 6.10 or later) on your PC. It's an IDE develop environment for the development on ARM based Micro-Controller. When you get all ready, you are able to download applications to OpenMoteSTM. The connection of OpenMoteSTM mote and PC by j-link to a PC is shown in following figure.

OpenMoteSTM Connection

After that, we should open IAR and select your project for stm32. Then click the green triangle button on the tool bar. The application will be downloaded into OpenMoteSTM and go into a debugging model.
