如果设置了ethernet模式,别忘记了还需要到Top - Component config - Ethernet - Support ESP32 internal EMAC controller修改以太网的引脚、时钟频率。 在Top - Example Configuration中配置esp32客户端要连接IP地址和端口。这里我设置我自己电脑的IP地址和端口,那就可以实现互连了。如下图。 如果你设置没有问题,然后...
arduino ide mpu6050的库 操作步骤: 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...

This example shows how to fade an LED on pin 9 using the analogWrite() function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins ...

of these buses both can be used. However when just using these the Arduino way only will actually be outputting at a time. Logic analyser capture is in the same folder as this example as "multiple_bus_output.png" created 30/04/2018 by Alistair Symonds ...
