Abandoned Posts
Over the past seven years (the age of this blog) I started writing several articles that I never finished. It’s time to trash them completely or just add them to a list for future afterthoughts. Who knows ? So, from older to newer: „Weller WD 1000 M Review – Part III – Software”, January 18, 2013 — …
SCPI on Mac
Some more days passed and some more finishing touches added to my MacSCPI app. It is entirely dependent on hooking the device via the USBTMC driver, but it works fine and is stable: I had some problems with buffer padding and the output it is still not 100% gibberish–free , but I assume I have to play with …

December again, another year passed. Traditionally, this is a month when I am taking a long break. But I was up to something in the past days and …
Usage of void in C
Going into some USB programming for a project I am into (on my Mac), I ran into this and I thought would be nice and useful to elaborate a bit. This is about void* pointers and callbacks in C. USB device discovery and probing under IOKit makes heavy use of callbacks, I wanted to write …
