应用设计中，用一条I2C总线驱动多个I2C设备师很常见，实施也很简单，本项目将连接以下I2C设备： Adafruit_GFX, Adafruit_SSD1306.h 和 SPI.h，控制SSD1306 128×32 OLED显示屏。 由于所有元件相距不远，没必要I2C总线使用上拉电阻，因为这些杜邦线就是组件的一部分。 本项目 ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Engineer, creator and tech journalist Jeremy Cook based in Tampa Florida has created a small mechanical keypad aptly named the JC Pro Macro 2 featuring 8 customisable keys, a rotary encoder GPI ...

Arduino enthusiasts or those looking to learn more about programming with Arduino and electronics-in-general may be interested in a new Kickstarter campaign and Arduino compatible 42-Digit SPI Keypad ...
