Testing a WeSU in everyday life

In this article, we will use a WeSU in some daily common scenarios. In this way, we will propose some case of use of wearable device, testing also its mechanical robustness and its sensitivity.

For our tests we will use the remote data capture feature provided by the smartphone app: this is very useful because it allows to save data and send them to an email address allowing offline post processing. Before starting each test, we need to pair WeSU and our smartphone using bluetooth: launch the application (ST WeSU) then click on START SCANNING (see Fig. 1).

SEGGER J-Link Pro: an exhaustive review

SEGGER J-Link PRO an exhaustive review

In our minds, we have always seen SEGGER debugging solutions like a professional but costly tools: a debugger to perform advanced operations but definitely too much for a student. Some time ago we heard about a new version of SEGGER, the J-Link EDU, which is cheaper and addressed virtually to us. It started to take shape the idea of using it as external debugger for these ARM evaluation kit which comes without a debugger.

Some month ago SEGGER proposed a firmware suitable for STM32 Nucleo on-chip debugger which makes J-Link available also for the STM32 ecosystem and they continue reading...

Review of WeSU: a development board for wearable applications.

Wesu Review

At the recent event “ST = Life Augmented”, held in Milan during the Class Digital Experience Week, STMicroelectronics has raffled various development kits, for attendees who enrolled to the event through the Pepite blog. Apart to the famous STM32 Nucleo-64 board and some of its Expansion Board (the STM32 x-Nucleo), the most interesting thing was the development kit for wearable applications, the STEVAL-WESU 1, valued at approximately 50€ and we were lucky to get one for free.

STEVAL-WESU1 stand for ST EVALution WErable Sensor Unit, and is an evaluation kit to test various continue reading...

STM32 Nucleo-144 review

STM32 Nucleo-144 Review

The STM32 Nucleo-144 is a new series of development board by STMicroelectronics. It is the third announced series titled Nucleo. Each Nucleo-144 share the same pin map for each board and features a new connector named ST ZIO which is compatible with Arduino Uno Rev3 connector.

This new series takes his name from the number of pads exhibit by its different MCUs which are all a LQFP144 package. Indeed, the STM32 Nucleo is currently available in 5 configurations we will discuss continue reading...
