Finally test the heart of your firmware. Open Loop Tests for microcontrollers.

[embeff @embeff]

It was great fun to co-exhibit with our Partner @SEGGERMicro at last weeks @emBOconference .

For Cortex-M based microcontroller, we use their J-Link technology inside the ExecutionPlatform to flash test binaries. The user can also open Segger Ozone and debug the test remotely!

You connect a logic analyzer like @saleae and then choose at runtime which pins you want to see. Without any rewiring. The visual support will make it much easier to implement #OpenLoop tests.

Today we are previewing the next generation ExecutionPlatform at @emBOconference.
It has built-in support for connecting an external logic anaylzer that lets you view any of your microcontroller pins.

shoutout to @Mentimeter
Great tool for conferences and thanks to @embeff for the first talk this morning about on-target vs. off-target testing. Check it out at https://t.co/ig4SRk2HIw - make sure to have the www. in front of it ;) Twitter shorthens it

[Daniel Penning @DanielPenning]

Tomorrow morning at 9 CET I will explain in a live session at the @emBOconference why the popular way of doing #unittesting in #embedded is broken. You will hear about C++ language quirks that may crash your device - even if you "tested" it. And much more.

[embeff @embeff]

Besuchen Sie uns nächste Woche auf dem Embedded Software Engineering Kongress. Wir freuen uns auf viele spannende Gespräche!
#Konferenz #Austausch

Wie sorgt man für Reproduzierbarkeit im Build Prozess? Sodass auch Jahre später alte Software-Stände angepasst und gebaut werden können?
Am Freitag gebe ich dazu im kostenlosen Vorprogramm des ESE Kongresses einen Vortrag.

I am looking forward to open @meetingembedded 2020 by explaining why the popular way of doing #unittesting in #embedded is broken. You will hear about C++ language quirks that may crash your device - even if you "tested" it. And much more. See you there!

In einem Grundlagenartikel bei Heise erklären wir Risiken, die durch Cross-Compiler entstehen.
Leider bleiben diese oft zu lange unbekannt - und unbemerkt.

C++20 Concepts haben ein enormes Potential, die Entwicklung für ressourcenbeschränkte Systeme zu stärken.
Im Hintergrundartikel erklärt @danielpenning, wie diese Chance entsteht und wie man sie nutzen kann.

Most developers are familiar with the term undefined behaviour. But the fact that this can quickly lead to very subtle deviations in off-target behaviour is not as well known.

Our latest blog post provides some background. https://t.co/HIGAKrRINK

Your testing may result in a purely “perceived security”.
Our latest blog post demonstrates the key technical reasons for differences between the on-target and off-target approaches.

Für alle die nicht am Webinar teilnehmen konnten, gibt es jetzt eine Video-Aufzeichnung.
Du lernst dort, wie eine On-Target Ausführung kritische Embedded Bugs aufdecken kann.

Ein Sicherheitsnetz für moderne #embedded Entwicklung?
In unserem morgigen Webinar lernt ihr Fallstricke der On- und Off-Target Entwicklung kennen.
Wie kann eine Ausführung auf dem µC mit der ExecutionPlatform dabei helfen?

Unit test results may depend on the compiler and target⚠️
We found an interesting bug in @ArmMbed by running the existing tests on a mikrocontroller.

See our latest blog post for details:

[embeff @embeff]

Is it worthwhile to optimize trig functions such as cos?
We investigated for the ARM Cortex-M4F architecture.

It is, but you need to take care and avoid pitfalls.

@KuestenPepe @emBOconference Yes, all ARM Cortex-M based MCUs are supported. Feel free to reach out with DM / [email protected] for remote session scheduling.

[Odin Holmes @odinthenerd]

talking to @embeff and @SEGGERMicro at @emBOconference I have realized we really need to step up our tooling game. I could have found so many bugs so much more easily in retrospect

[embeff @embeff]

@emBOconference Many thanks for having us! @emBOconference is a great place to showcase the ExecutionPlatform in public for the first time.
