Another pin is GPIO0, one of the strapping pins. If IO0 is held low during power-up or reset, the ESP32 goes into bootloader mode, which is useful for flashing new firmware. Here’s an example Arduino code that resets the ESP32 every 5 seconds: void setup() { // Your setup code...
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。由于我的esp32的板载LED灯的pin number是2,修改#define LED_PIN 13为2。 // I2C device class (I2Cdev) demonstration Arduino sketch for MPU6050 class // 10/7...
