Started 7Jul2019, updated 14Dec2022 («RISC-V») This page is in group Technology and is a blog note where I will try to find out how to have my aquarium’s temperature coming from an IoT box. Hopefully a box. Alternatively but less of IoT data via Apache on my iMac. Intro The XMOS startKIT was and the XCore-200 eXplorerKIT […]
New 5May2019, updated 8Sep2019 This note is in group Technology (plus My XMOS pages and Aquarium pages) describes my only real invention this year: a USB 5V in and USB 5V out, where the 5V out will only be kept as long as a built-in watchdog timer is fed with an edge of a signal from an […]
Started 8Jan2019, updated 9Nov2021 (Timed C) This page is in group Technology and is a blog note where I will try to have a fresh view (as of 2019) of what might be going on with concurrency and Real-Time Operating Systems (RTOS) in the small embedded systems world. Here I would think mostly of what might run […]
Started 13June2018, updated 02Nov2023 (Søren with photo next to the final solution) This page is in group Technology and is a blog note about my experience with two subwoofers. One had trafo and membrane hum, the other magnetic induced iron hum. (I have some other audio blog notes. Like My processor-to-analogue audio equaliser notes, My Beep-BRRR notes / […]
Started 2Feb2018, updated 13May2021 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 is xC […]
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; […]
Started 1Nov2017. Updated 8Jan2019 (See Zephyr operating system). In work This page is in group Technology (plus My XMOS pages) and is a blog note where I will try to work myself through.. ..having run the Arduino WiFi101 library on an Adafruit Feather ARM M0 basic proto board, a variant of the Arduino Zero using a WiFi board that […]
Started 6Oct2017. Udated 10Aug2018 This page is in group Technology (plus My XMOS pages) and is a blog note where I will try to describe a WiFi card (that I call PiggyBack WiFi1500 sliceCARD) that is meant to replace another WiFi board (XMOS WiFi sliceCARD) and be a pin plug-in replacement, meant for the two XMOS boards startKIT and […]
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 […]
