There is a mistake in info in UART pins usage. Mostly a typo. Check for the line,“Hence, we can not use UART2 directly without reassigning pins in Arduino IDE.” which should be “Hence, we can not use UART1 directly without reassigning pins in Arduino IDE.” Reply tom December 7, ...
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...
