A CAN driver for the ESP32

Last year I ordered an ESP32, a chip that got quiet a lot of attention because it is small, affordable and comes with a free SDK. I worked with the predecessor, the ESP8266 and I think that the ESP32 is way easier to use and the SDK (called ESP-IDF) is much more powerful compared with the ESP8266. Time to get...

🇩🇪 Warp3 auf allen Kernen

Entwicklung einer schnellen und sicheren Multicore-RTE Multicore Mikrocontroller bringen aufgrund ihrer Komplexität besondere Herausforderungen, wie die Inter-Core Kommunikation und den Schutz von Ressourcen vor unerlaubtem Zugriff mit sich. Zudem ist die Parametrisierung und Nutzung immer leistungsfähigerer und umfangreicherer Peripherie komplex und fordert den Anwender somit zusätzlich. In Kooperation mit einem Industriepartner wurde eine innovative Laufzeitumgebung...

Multicore microcontroller programming

Since the 70’s, Moores Law was the driving force behind the increase of computing power. As we know, we start to reach the physical limitations of downscaling, which made higher frequencies possible but also lead to higher leakage currents and therefore power consumption and heat. As squeezing a lot more GHz out of the circuits...

Functional Safety on Multicore Microcontrollers for Industrial Applications

Besides the gain in performance, a strong motivation for the introduction of multicore microcontrollers is the realization of safety architectures. Together with an industrial partner it was investigated if safety critical applications, which require a PL d according to ISO 13849, running until now on redundant discrete microcontrollers can be replaced with an architecture running...

An introduction to CANopen

I had to interface motor-controllers with CAN, CANopen to be specific. The Name CANopen suggests that this is some kind of open standard with tons of free Stacks and documentation, right? No, not at all. I had a hard time implementing a own CANopen-Stack on a PSoC 5LP. I want to change these circumstances by...

🇩🇪 Es ist geschafft - wer hätte das gedacht?

Rede zur Verabschiedung der Absolventen der Elektrotechnik an der Hochschule Darmstadt - 2015 und ein Zwischenfazit meinerseits. Denken Sie an den Beginn Ihres Studiums.   Wie fühlten Sie sich? Erwartungsvoll? Ängstlich? Aufgeregt? Unsicher? Wie reagierten die Menschen in Ihrem Umfeld auf Ihren Entschluss zu studieren? Ich hatte Angst. Ich wusste nicht was auf mich zukommen würde...

Exoskeleton simulator project finished

The last month my girlfriend and I had been working on a system to capture leg movement and animate a skeleton together with a exoskeleton. The motivation was to improve the "mobility in the city". We found that people using a wheelchair often fell "unequal" as they are simply not on the same height as "normal"...
