Getting LoRaWAN working with STM32WL55 and Radiolib

Sun, 28 Jan 2024 17:24:03 +0000

Elektor was looking for some ideas regarding their STM32 Design Contest - and so I thought, why not putting the excellent work of the guys behind the RadioLib to good use and getting this board working in LoRaWAN (and it was easier than I thought :)):

USB C power for the Nvidia Jetson Nano 4 GB dev board

Mon, 17 Oct 2022 08:00:00 +0000

The best way to power a Jetson Nano 4 GB dev board is by using a center positive, 5 V and at least 4 A barrel connector type power adapter. However, these are often bulky and not the best travel companion - while USB C power bricks are becoming more common and the relevant USB C sockets are getting build into nearly every device (maybe yours too, Apple?).

So I set out to build a USB C power adapter for the Jetson board.

WD My Cloud Mirror Gen2 with Debian 11 and Linux Kernel 5.15 LTS

Intro

Since 2017 I have been using an Western Digital My Cloud Mirror Gen 2 which I bought at Amazons Black Friday (or similar) - because the included 2x 8 TB WD Red were even cheaper with the NAS than standalone. Using the NAS had been quite ok, especially the included Docker Engine and Plex Support were a nice to have, the included Backdoor in older Versions - not so much. Recently WD had their new “My Cloud OS 5” replace the old My Cloud OS 3 - and made things worse for a lot of people. As I don’t want any more surprises - and more control over my hardware - I decided to finally go down the road and get Debian 11 with an LTS (5.15) Kernel running on the hardware. This is how it went.

Getting started with Infineon XMC for Arduino

Tue, 07 Mar 2017 16:45:09 +0000

Infineon created the ARM Cortex M Series “XMC” in 2012 to give their users access to a rich portfolio of different AMR Cortex M0+ and M4 MCUs. These Microcontrollers, being supported by powerful peripherals had support for two different IDEs: Keils MDK and Infineons DAVE. While Keil is the definitive choice for most professionals (and expensive…), DAVE was an self-developed plug-and-play kind of programming tool, using Eclipse as framework. However, both tools were directed towards professional endusers and developers, while hobbyists and makers with less experience in ARM Cortex programming would have a sturdy learning curve. Seeing that, and the first tests of the fanproject XMC-to-Arduino - Infineon decided to create an own boards package for the Arduino IDE. And thats what finally arrived some days ago :)!
