Many people are asking questions about how to use its GPIO pins. Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use thi
这些是可用作 ADC 和相应通道的 GPIO: ADC1_CH0 (GPIO 36) ADC1_CH1 (GPIO 37) ADC1_CH2 (GPIO 38) ADC1_CH3 (GPIO 39) ADC1_CH4 (GPIO 32) ADC1_CH5 (GPIO 33) ADC1_CH6 (GPIO 34) ADC1_CH7 (GPIO 35) ADC2_CH0 (GPIO 4) ADC2_CH1 (GPIO 0) ADC2_CH2 (GPIO 2) ADC2_CH3 (...
ESP32-C3 SPI Pins as GPIO Mon Mar 04, 2024 7:25 pm I have a project with the ESP32-C3 chip, and I need to use the SPI pins (SPICS0, SPICLK, SPIQ, SPID) as GPIOs since I don't have any more available pins. I understand that these are internally connected to the flash....
In this tutorial, we will learn how to use GPIO pins of the ESP32 devkit with LED blinking examples using Arduino IDE. Whenever any beginner starts learning about any microcontroller-based development board, Experts always recommend beginners to start with an LED blinking example which is also kn...
ESP32 Interrupt Example Code (in Arduino) In this section, I’ll give you a step-by-step approach for what to do in order to configure and initialize an external interrupt pin and assign it to an ISR handler function. Step1– Decide on the external interrupt GPIO input pin that you’re...

The ESP32 PWM hardware has 16 different channels, not pins. You can assign any of these channels to any GPIO pin that you want. But it has to have an output driver or in other words, it should be capable of operating as an output pin. In our ESP32 dev boards, all the GPIO pins...
