Il nucleo terrestre non è più un mistero immutabile: la scoperta che il centro della Terra può deformarsi apre scenari inaspettati sulla rotazione del pianeta e sul campo magnetico. Una rivelazione che rivoluziona decenni di teoria geologica, con potenziali effetti sulla durata del giorno e sul campo magnetico.

[Перевод] Создаём своё первое USB-устройство
Сегодня мы поговорим о создании USB-устройств, подключаемых к компьютеру и распознаваемых им. Этот пост задумывался как ваш первый источник для знакомства с разработкой USB-устройств. Сначала небольшое предупреждение: я не считаю себя экспертом в USB. Не рассматривайте пост как авторитетное руководство; скорее, это документация к моему небольшому проекту по созданию простейшего USB-устройства E2E. Также в нём приведены ссылки на хорошие материалы, в которых тема рассмотрена более подробно.

Tengo que actualizar el núcleo? como me lo pide el gestor?
This is the 2020's #STM32 #Nucleo—a tiny, lower-power 32-bit #MCU—it's significantly more powerful than the top-end workstations I used in the 1980s.
Some 40ys of perspective....

Ich habe hier ein #STM #Nucleo Board, bei dem der ST-Link Teil nicht mehr funktioniert (wird auf dem PC nicht mehr richtig erkannt). Kann man den Teil des Boards irgendwie neu flashen und eine neue ST-Link Firmware einspielen? #followerpower #STLink #STM32 #Embedded #development
"A reação ocorre após reportagem do #Núcleo mostrar que advogados da empresa norte-americana #Meta no Brasil acusaram o #Netlab, um laboratório de pesquisa da #UFRJ, de ser "enviesado" e "não atuar de forma técnica" após estudos do grupo servirem de base para uma multa contra a rede social, que não removeu anúncios fraudulentos de suas redes após uma notificação."

Studiosi del Woods Hole Oceanographic Institution e del Caltech hanno scoperto alti livelli di elio-3 su un'isola nell'Arcipelago artico canadese: è la conferma che dal nucleo terrestre sta fuoriuscendo materiale che credevamo confinato al suo interno, e l'inizio di una nuova era nella geologia.
Finished a first analysis of the input referred noise of the ruwai-mini data recorder. The image shows the acceleration power spectral density of the input referred electronic noise referenced to a 4.5 Hz passive geophone with a sensitivity of 80 V/m/s. All geophone output signal lower than the data logger noise floor will be covered by the electronic noise.
The orange line shows the self noise of the geophone - almost a perfect combination.
Happy with it.
Didn't post much about the Ruwai-mini development the last days, but I made quite a progress. I finished a first working prototype which is logging timestamped digitized seismic data in miniseed format to an SD card. It's now time to clean up the code and search for software bugs. I'll post some detail about the prototype in the coming days.
The image shows the breadboard setup of my prototype. Cleaned up the jump wire mess a little bit....
At all #embedded folks can someone recommend a good starter #breakoutboard / #sensorkit for getting started with a #stm32 #nucleo board in my lessons. #teaching
Waiting for the next release with excitement :ablobattention:

Thank you Pascal Kuthe and all the contributors :blobcatrainbow:

I'm currently testing the low pass FIR filtering for sampling rate conversion on the NUCLEO-L496ZG board. The CMSIS-DSP library provides all the required tools and the results are looking great. The image shows the comparison of the original sampled data based on a free running clock, the interpolation to a regular time grid aligned with the GNSS time and the low pass filtered signal.
I have switched from sample-based to frame-based processing of the ADC samples. This improved the timing a lot. The image shows the timing from the data ready signal (red channel), the DMA sample transfer (green), the DMA RX Ready interrupt (yellow) and the processing of one frame holding 50 samples (turquoise). The sampling rate is 4800 sps. The frame is processed within one sampling interval and the ADC retrieval uses only ca. 5-10 us of processor time.
The #rust ecosystem is getting bigger with the creation #nucleo from one of the very talented #helix developers.
A faster fuzzy matcher replacement compared to #fzf and #skim.

The Ruwai-Mini development is in progress. Today I have finished the first draft of the data interpolation to a regular time grid. The ADC is running free with the internal clock. I'm using the GNSS PPS signal and the timer of the microcontroller to interpolate the data to a regular time grid aligned with the GNSS time. The data checks are promising. The image shows the free running data (blue line) and the interpolated data (orange line).
