My aquarium’s data radioed through the shelf

Started 23Dec2017. Updated 2Dec2020 This page is in group Technology (plus My XMOS pages) and Aquarium pages. The My WiFi101 library port or an Ethernet based web server was not implemented following this work. I also did not use the Bluetooth Low Energy (BLE) suggestion as discussed in Me relying on relaying BLE? I went for the simpler (?) packet radio […]

Me relying on relaying BLE?

Started 7Dec2017. Concluded 23Dec2017 This page is in group Technology (plus My XMOS pages) and is a blog note where I will discuss the route ahead. Should I do the My WiFi101 library port as I promised myself to try, or should I add a second box that I talk with over BLE (Bluetooth Low Energy)? Conclusion 23Dec2017: I did neither; […]

My single-board boards and why notes

Started 15Sept2017, updated 08Apr2024 (Efficient Computer Corp., xCORE-200 soon EOL, xcore.ai evaluation kit (was Explorer board) This note is in group Technology, (plus perhaps My Beep-BRRR pages and My XMOS pages) and is a blog note where I will try to lay out the reasons why I have ended up with some single-board microcontroller (not computers) and not some […]

My xCORE-200 eXplorerKIT notes (WiFi)

Started 6Aug2017, updated 14Dec2022 («RISC-V») This page is in group Technology (plus My XMOS pages) where I will try to add matters about my XMOS xCORE-200 eXplorerKITs that I haven’t found elsewhere. I purchased two of these boards in the summer of 2017. It turned out to become an XMOS embedded WiFi blog note. This note has ended […]

xC is C plus x

Started 7April2017, updated 02Jul2024 (XCore Exchange bullet 2. Replicated select case) This page is in group Technology (plus My XMOS pages) and is a blog note trying to scribble down some info about the XMOS xC language that I haven’t found elsewhere. I love it. But, alas, xC appears as C plus unknown X. I’ll help finding min(X). Also […]

Swift concurrency(?)

New 12Jan2017, updated 2Apr2019 Intro In this note I will try to track what’s happening with Swift and concurrency. I already have mentioned Swift some (https://www.teigfam.net/oyvind/home/?s=Swift) and I won’t repeat here – only to say that there per se, at the moment, is no concurrency support in the language. Swift 3 users are supposed to use […]

Towards a taxonomy(?) of CSP-based systems

New: 12Oct2016. Last updated 25Aug2021 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. Fold handling with Collapse-O-Matic plugin I am using Collape-O-Matic (here) […]
