You can view all the analog pins in the ESP32 pinout diagram above. Digital to Analog Converter Pins Digital to Analog Converter (DAC) pins enable the generation of analog output signals. This feature is valuable in applications like audio synthesis and precision control systems. The ESP32 has...
关于esp32 s2 mini 的I2C,begin必须分开写,不知道原因。 voidsetup(){Wire.setPins(SDA_PIN,SCL_PIN);Wire.setClock(5000);Wire.begin();} 关于两路I2C可以这么写。 TwoWire WireA=TwoWire(0);TwoWire WireB=TwoWire(1);voidsetup(){WireA.begin(DEVICE_ADDRESS,I2C_IN_SDA,I2C_IN_SCL,5000);WireA....
