The digital signal is being measured in this application example by using an external interrupt pin + a Timer module. On the first rising edge, an interrupt occurs, so the CPU suspends the main program execution and starts a timer module, and then it resumes the main program. On the next ...
This ESP32 tutorial will explain and solve a particular problem of sampling the analog-to-digital converter (ADC) from a timer interrupt. We will use the Arduino IDE. Even if it is one of the worst IDEs out there in terms of feature sets, the Arduino IDE is at least easy to set up ...

打开file-example-mpu6050-mpu6050_DMP6,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。中断pin 2修改为#define INTERRUPT_PIN 13 //修改后 #define INTERRUPT_PIN 13 // use pin 2 on Arduino Uno & most boards #define LED_PIN 2 // (Arduino is 13, ...
打开您的Arduino IDE，然后导航到File > Examples > ESP32 > Deep Sleep，然后打开TimerWakeup草图。
