Fixing Zephyr Environment on Linux

I’m actually experimenting with Zephyr, a Real Time O.S. for IoT devices. It seems very impressive for many aspects, that, out of the topic of this blog post, I list here. It’s a fully fledged microkernel with many drivers for peripherals and protocols It supports many important protocols like Wifi, Bluetooth Low Energy, OpenThread (and Matter) and many others It’s supported and financed by Nordic Semiconductors, It’s open source It has many hardware supporting it, including Nordic chipset, STM, Espressif, Raspberry, etc… It has an extension for Visual Studio and others IDE are supporting it, like, for example, Jetbrain’s CLion So I decided it’s time to test it.

Not all Arduino Nanos Are Built Equals

Not all Arduino Nanos are built equals. I have two samples here, one bought from AZDelivery and one in a NanoCUL. Though both are Nano v3s, they are somhow different. Indeed, I was able to program the second out of the box using avrdude, while I had some issue with other. Using PlatformIO I noticed that the first was not properly configured on my system. Indeed lsusb shows different chips are used: Continue reading

How to switch "\" with "<" keys in linux

When using the Apple Magic Keyboard with linux and certain keyboard layout, some key may be exchanged with some other key. In my case, I have an Italian Magic Keyboard and a Ubuntu 20.10 running on VmWare Fusion and the “" and “<” keys are switched. The fix is pretty easy, but not easy to find on the net. This is the recipe: you need to force xmodmap to exchange the two keystrokes. Continue reading
