In thesetup(), you initialize the button as anINPUT, and the LED as anOUTPUT. For that, you use thepinMode()function that accepts the pin you are referring to, and the mode:INPUTorOUTPUT. pinMode(buttonPin,INPUT);pinMode(ledPin,OUTPUT); In theloop()is where you read the button st...
This is a output pin for ESP peripheral. This pin is used to indicate host that the ESP peripheral wants to send a data packet to it. This pin stays high till the host reads this data packet. Reset/EN pin This is a input pin for ESP peripheral. This pin resets ESP peripheral and i...
SPI(Serial Peripheral Interface)是串行外设接口的缩写,是一种高速的,全双工,同步的通信总线,并且在芯片的管脚上只占用四根线,这四根线分别是: MISO– Master Input Slave Output**,**主设备数据输入,从设备数据输出,也称SDO。 MOSI– Master Output Slave Input,主设备数据输出,从设备数据输入,也称SDI。 SCLK...
The ESP32 offers a range of General-Purpose Input/Output (GPIO) pins, allowing digital signals to be read or output. These pins are crucial for interfacing with sensors, actuators, and other digital devices. The ESP32 has 34 GPIO pins in total numbered GPIO0 to GPIO39. Some GPIO pins ar...
General Purpose Input Output Pins (GPIOS) Almost all GPIOs have a number assigned and that’s how you should refer to them—by their number. With the ESP32 you can decide which pins are UART,I2C, orSPI– you just need to set that on the code. This is possible due to the ESP32 ...

important to pay attention to General Purpose Input / Output (GPIOs), that is, programmable data input and output ports, which can still be an AD converter or a Touch pin, such as GPIO4, for example. This also occurs with the Arduino, where the input and output pins can also be PWM...
