Wenn man auf einem #SAMD21 basierten #Mikrocontroller in der Wire Library Wire.setClock < 91000 Hz setzt, kommt es zu einem Überlauf und der #I2C Bus läuft deutlich schneller als eigentlich gewünscht.

Hier werden zum Beispiel bei gesetzten 75000 kHz in Wirklichkeit 342 kHz erreicht. #Arduino

As for me and my house, we will use blue wires for the clock signal because it reminds me of water clocks.

Review of HackerBox 0122 - Ouroboros This month's box includes a OVcam based camera board and ECG measurement board! Also, I got a lot of nice new tools from the holidays that help me out with the build.

Of course, you don't need a switch to use multiple devices on an #I2C bus *unless* they have the same address, and can't be changed.

STMicro ST25DA-C is the first NFC chip with Matter support ST ST25DA-C is an NFC chip with built-in support for the latest Matter 1.5 protocol, enabling easier installation of smart devices on home networks, including lighting, access control, security cameras, or any IoT device. NFC here is used as an alternative to Bluetooth LE or QR core commissioning. NFC tap-to-pair functionality enables users to tap an NFC tag code on a device with their smartphone to securely and easily add it to their Matter-compatible app(s) and network(s). Besides batteryless commissioning, the ST25DA-C chip can also be used for firmware updates over I2C (Matter OTA), and secure storage for keys & certificates. ST25DA-C secure NFC tag specifications: Contact interface 1.62 V to 3.3 V supply voltage range ESD protection Human body model (HBM): 6 kV for digital and antenna pads Charge device model (CDM): 1 kV based on a STMicroelectronics module I2C serial interface up to 400 kHz Contactless interface Power [...] The post STMicro ST25DA-C is the first NFC chip with Matter support appeared first on CNX Software - Embedded Systems News.
