(Parent) Started 04Nov2019, updated 16Mar2022 (iCircuit, fritzing, KiCad). In work. This note is in group My FPGA pages and is a follow-up from My FPGA notes where the IceCore has been discussed extensively. This note is going to be with the hands-on experience, since I am at the moment (05Nov2019) awaiting two boards in the mail. Fold handling with […]

Started 2Feb2018, updated 13May2021 (Style: 02.05.2025) This page is in group Technology (plus My XMOS pages) and is a blog note with some XMOS xC code examples. I also have some ported code that I thought may be placed here. I also am describing some problems.  None of this is on GitHub. I guess that the parent note […]

Started 18April2016 – updated 22Nov2021 This page is in group Technology. Technical debt exists as a term. It doesn’t seem like technical deposit is a corresponding term. I try to do something with this here. (Observe that «depth» (with p and th) is how deep something is, it has nothing to do with «debt» that’s […]

There is a nice series of development boards by ST called STM32 MCU Nucleo (here [1]), based on an ARM. One of these appeared on a table near me. They guy who had it said that «they also tell about a free operating system». It happened to be FreeRTOS™ (here [2]) by Real Time Engineers Ltd on freertos.org [3]. I eagerly looked it up and was fast pointed to WITTENSTEIN HighIntegritySystems (by The WITTENSTEIN Group) here [4]. They do SafeRTOS, so I downloaded its manual here [5]. This is a IEC 61508 (here [6]) approved RTOS. Since I work with safety critical systems (and have some blog notes here covering some aspects of 61508, like in note 065 [7]) I started to read. It spurred some questions.

New: 03Nov2016. Last updated 19Ju2026 aPyCSP This page is in group Technology. This note started with an attempt to look at how channels are modelled (in code, really) but then ended up with trying to systemise what I found. The note was even called Channel structures at the start. Towards a classification of CSP-based systems? This might be […]
