先日 Arduino と Raspberry Pi を USB シリアル通信で連携しながら、温度湿度を取得するセンサーを作ってみました。今回はそこから得た知見を書いていきます。 開発環境 今回の開発で使用する環境は以下のようになります。 今回開発に使用したPCは「MacBook Pro 2016 ...

[Hans Peter] wanted to move away from using full Arduino boards in his projects. One of the components he rarely used after the development stage is the USB hardware. Once the firmware is flashed to ...

Arduino Leonardo を USB HID デバイスとして複数台接続した際、Windows や X-Plane 上で個別に識別できるように、製品名（Product） と シリアル番号（Serial Number） を変更します。 uint8_t HID_::getShortName(char *name) { Arduino コアやライブラリをアップデートすると、boards.txt や ...

Have often wished it were possible to monitor program execution when the serial port is exchanging data with another device. An LCD display could be used for that but those are somewhat difficult to ...

Port of the ESP-IDF USB host HID example to the Arduino IDE with minimal changes. This is an Arduino library so install it in your Arduino library directory. The easiest way to do this is to download ...

[Andrew] wonders why the SerialUSB() function on the Cortex M3-based Arduino Due is so much faster than Serial() on the Uno or Nano, and shares his observations in this short video. He sets up an ...

The USBISO-AA is an isolator / repeater with transient protection, featuring 1kVolt isolation for USB 2.0 Full-Speed devices. Hjelmslund Electronics' introduces their new USBISO-AA isolator and ...

The universal serial bus (USB) is rapidly becoming the standard interface for most PC peripherals. It is displacing RS-232 and the parallel printer port because of superior speed flexibility and ...
