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 […]

On any second read, you’re allowed to press the links. This note is my first reaction to the surprising and bold switch by XMOS, to let the xcore architecture run […]

My xC combined combinable notes

Started 16Feb2021 – updated 20Apr2021 – about finished. This note is in group Technology (plus My XMOS pages). For the TIOBE index 016:[10]: «xC programming». Observe that [[combinable]], as well as [[combine]] are xC keywords. Combined, as in the title, is not. I assume that much of xC’s terms are known. Fold handling with Collapse-O-Matic […]
