P&E has a new version of their GDB/Eclipse debug plugins available on their Eclipse update site, and it comes with to great features: Real Time Expressions (show variables while target is running) andΒ FreeRTOS thread awareness π

What is a Sunday morning without a perfect breakfast? With a Sous-Vide cooker in the kitchen, this small research project is about preparing Eggs Benedict Sous-Vide style:

Instead creating a new project from scratch, often it is simpler to copy an existing Eclipse CDT project, then change it and go on.Β To copy-past the a project in Eclipse:
Copy of a project
Paste of Project
However, to make that process simpler, a few things have to be done right in the ‘source’ project first.
I’m a big fan of ‘low-and-slow’ cooking, and that’s why I love my BBQ Smoker. That smoker is great for Ribs, Brisket or Pulled Pork. But it is not ideal for other pieces of meat. After doing some research, this weekend I tried something differently: “Sous-Vide”. The result is delicious: this is by far the best steak I’ve ever cooked :-).

For a CubeSat project we only have a single board available. But multiple universities and developers need to have access to that board for developing and debugging the firmware. We cannot easily ship around the board: that takes a lot of time and during shipment nobody can use the board.
There is a nice feature in the Segger J-Link software which allows to share the debug connection over the network: the J-Link Remote Server. It even works nicely between different networks without complicated firewall setup:

Maybe you remember my recent post “Schwanau on Ice” with walking on the frozen Lake Lauerz? I mentioned in that post that there are natural gas bubbles caught under the ice. There is a long (and dangerous!) tradition to burn that gas. That this is really dangerous shows this a short video going viral on ‘WhatsApp’ today:

Some ARM Cortex-M have a DWT (Data Watchpoint and Trace) unit implemented, and it has a nice feature in that unit which counts the execution cycles. The DWT is usually implemented on most Cortex-M3, M4 and M7 devices, including e.g. the NXP Kinetis or LPC devices.

During cold winters the Lake Lauerz gets covered with ice. And if it is cold enough for a few weeks it gets enough ice to have it completely covered more than 15 cm of ice. That’s the time of the year to enjoy a walk or to play ice hokey:

I’m pleased to announce that a new release of the McuOnEclipse components is available in SourceForge, with the following main features and changes:

The concept of Linux (Open Source, broad developer base and broad usage) is a success story. While there is a lot of diversity (and freedom) in the Linux world, Linux is Linux and again Linux :-). And the world has (mostly) standardized on Linux and its variants on the high embedded system side.
On the other side, the ‘middle and lower end’ Embedded world is fragmented and in many aspects proprietary. So it was no surprise to me when the Linux Foundation announced the ‘Zephyr’ project back in February 2016:
“The Linux Foundation Announces Project to Build Real-Time Operating System for Internet of Things Devices. Open source Zephyrβ’ Project aims to deliver an RTOS; opens call for developers to help advance project for the smallest footprint IoT devices.“
ΞΞ΅ΟΟ ΟΞΏΟ (Zephyros) is the Greek good of spring and the west wind. Obviously this inspired the logo for the Zephyr project:
