在我们开始使用两个 Arduino 进行 I2C 编程之前。我们需要了解Arduino IDE 中使用的Wire 库。 《 Wire.h 》 库包含在程序中,用于使用以下函数进行 I2C 通信。 1. Wire.begin(地址): 用途: 该库用于与 I2C 设备进行通信。这将启动 Wire 库并作为主机或从机加入 I2C 总线。 地址:7 位从机地址是可选的,如...
This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to ...
The software I2C libraries are generally master-mode only. There are a few I2C software slave implementations, but they do not follow the I2C requirements and are only for one type of processor. LibraryHardware / SoftwareArduino Wire compatible functionsMultiple I2C busesSlave modeRX/TX Buffer Size...
There are examples in many of the classes that demonstrate basic usage patterns. The I2Cdev class is built to be used statically, reducing the memory requirement if you have multiple I2C devices in your project. Only one instance of the I2Cdev class is required. Recent additions as of late ...
// if read continuous mode is enabled for only 1 i2c device, disable // read continuous reporting for that device if (queryIndex <= 0) { queryIndex = -1; } else { queryIndexToSkip = 0; // if read continuous mode is enabled for multiple devices, // determine which device to stop...
**Versatile I2C Expansion** The diymore TCA9548A I2C IIC Multiplexer Breakout Board is a versatile solution for expanding your Arduino projects with multiple I2C devices. With its 8-channel design, this board allows you to connect up to 8 I2C sensors or modules with the same address, enabling...
As of Arduino 1.0.1, requestFrom() accepts a booleanargumentchanging its behavior for compatibility with certain I2C devices. If true, requestFrom() sends a stop message after the request, releasing the I2C bus. If false, requestFrom() sends a restart message after the request. The bus will ...
This Gravity: I2C HUB module is designed to connect up to 8 I2C devices to a main-controller, which allows you easily to hook up multiple I2C devices in project building, for instance, useGravity-4P I2C/UART sensor cableto connect with Gravity modules or useJumper Wireto connect with Breako...
把esp32和mpu60插入面包板,用跳线连接二者,使用i2c通信协议,一共需要四根线,分别是电源正vcc,地gnd,数据sdl和时钟scl。 打开arduino ide,在库中搜索mpu6050,然后安装它。第一个库,我的已经安装好了,如下图。 打开file-example-mpu6050-mpu6050_raw,有现成的实例代码。
