We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 ...

前回までで、Raspberry Pi ZeroにCO2センサをUART接続し、測定値の読み取りと記録、LEDによる濃度のお知らせを試してみた。 今回から、センサとしてI2C接続で利用する環境センサ(温度、湿度、気圧などが測定できるセンサ)を使って、I2Cでのセンサ利用を試してみ ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

More often than not, an IoT master device uses the SPI (serial peripheral interface) and I 2 C (inter-integrated circuit) protocols to exchange data with EEPROMs or sensors that are operating in slave ...

Serial Kickstarter campaign creators SwitchDoc Labs have now launched their fourth campaign via the crowdfunding website to raise the required funds they need to take ...
