The following article gives a short overview on how to use and customize the emSBC-Argon to add sensors and graphic user interface. The goal of this little project was to integrate sensors from a Raspberry Pi pHAT and display the results on a QT5 user-interface. In this article, we describe two sensors examples which are the BMP280 from Bosch for temperature/pressure and the LSM303D from STMicroelectronics accelerometer.
The SBC-SAMA5D36 is based on the Microchip ATSAMA5D36 processor and supports the Linux operating system. The previous Linux version Yocto Dizzy (1.7) has now been replaced by the current version Yocto Sumo 2.5.3. Read the details in the following article.
How versatile and customizable emtrion's modules and baseboards are is also demonstrated by the successful attempt to use the SBC SAMA5D36 and the emSTAMP Helium as an Ethernet-CAN-Gateway.
Today software installation is facing lot of issues and many problems to overcome, especially into the expandable world of IoT devices. The firm Canonical is aiming to fix this with the snapcraft project (https://snapcraft.io). Snaps are containerised software packages that are simple to create and install. They auto-update and are safe to run. And because they bundle their dependencies, they work on all major Linux systems without modification.
The emSBC-Neon is a single board computer with the emstamp-neon module. This module is powered by the STM32F469 from STMicroelectronics and run FreeRTOS. In this blog post, we are going to see how we can add a simple task (or thread) using the set of free tools from STMicroelectronics. If you are not already familiar with the tools, please read the
“emSTAMP-Neon Software Manual Developer Kit” available on our Support page.
Today it’s important that the systems we use all day are functioning properly and constantly. Sadly, they also need constant electricity which can fail sometimes. To prevent a system to immediately crash with such a power fail, a UPS can be really helpful, especially when it comes to servers, data storages or even life supporting systems. A UPS, as his name describes, is an Uninterruptible Power Supply and provides emergency power to a load when the main power source fails. It guarantees to provide power for a defined amount of time so the supplied system can save critical data and shut down properly. And now comes the question how such a UPS function can be used in today’s embedded segment.
