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。由于...
3. 验证esp32c3配置arduino IDE CORE ESP32核心板是基于乐鑫ESP32-C3进行设计的一款核心板,尺寸仅有21mm*51mm,板边采用邮票孔设计,方便开发者在不同场景下的使用。核心板支持UART、GPIO、SPI、I2C、ADC、PWM等接口,可根据实际需要选择。 其中LED控制 合宙CORE ESP32核心板板载2颗LED,开发者可参考表4-1进行对应...

Now, in order to establish the serial communication with the ESP32 over Bluetooth, we will need an additional serial monitor, so we can send the data to the device. Although we can open a new instance of the Arduino IDE and open a new terminal for the Bluetooth emulated COM port, I’...

常见的支持I2S的Arduino开发板包括ESP32、ESP8266、STM32系列等。如果你的开发板不支持I2S,可以通过外接I2S编解码芯片(如MAX9867、WM8960等)来实现音频输入功能。 硬件连接示例(以ESP32为例): I2S数据线(DATA) :连接到开发板的I2S数据输入引脚(如GPIO35)。 I2S时钟线(BCLK) :连接到...
The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3 (embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,and features Wi-Fi®, Bluetooth® LE, debugging via native USB...
