Esp32 gpio

However, esp32 gpio, there are a few things to keep in mind, so please read the pinout carefully. Please note that the following pinout reference is for the popular pin ESP32 devkit v1 development board. Not every ESP32 development board exposes every pin, but each pin works exactly the same no matter which development board you use. Although the ESP32 has 48 GPIO pins in total, only 25 of them are broken out to the pin headers on both sides of the development esp32 gpio.

The ESP32 chip comes with 48 pins with multiple functions. Not all pins are exposed in all ESP32 development boards, and some pins cannot be used. What pins should you use? What pins should you avoid using in your projects? The ADC analog to digital converter and DAC digital to analog converter features are assigned to specific static pins. Although you can define the pins properties on the software, there are pins assigned by default as shown in the following figure this is an example for the ESP32 DEVKIT V1 DOIT board with 36 pins — the pin location can change depending on the manufacturer. Additionally, there are pins with specific features that make them suitable or not for a particular project.

The table below provides more information on pin usage, and please note the comments in the table for GPIOs with restrictions. For more infomation, please refer to ESP32 datasheet. Below is an example dump:. It is strongly not recommended to reconfigure them for other application purposes. These pin functions can be used when:. The Ultra Low Power co-processor is running. This header file is a part of the API provided by the driver component. To declare that your component depends on driver , add the following to your CMakeLists. Reset an gpio to default state select gpio function, enable pullup and disable input and output. If you want to set the trigger type of e. Please refer to Section 3. If you want to enable an interrupt on e. If you want to disable the interrupt of e. If you want to set the output level of e. If you want to get the logic level of e.

We have a project in which we build a shield for the ESP32 board.

There are plenty of ESP32 boards out there with different pin arrangements. Here is a detailed pin diagram of 2 different ESP32 boards. It will be beneficial to know the specific functions of each pin:. Pinout of an ESP32 board.

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 this board safely? You will get the answer to these questions in this article.

The ESP32 is a powerful and versatile microcontroller board widely used in IoT and embedded systems projects. Below is the detailed description of the ESP32 pinout:. VCC : This pin provides the power supply voltage typically 3. Connect a stable power source to this pin. GND : Connect this pin to the ground of your circuit. To enable the module, connect this pin to the VCC pin. Trigger a reset by connecting this pin to the ground momentarily. These pins can be configured as inputs or outputs and used for various purposes in your project. Analog Input Pins : The ESP32 has multiple analog input pins that can be used to read analog signals from sensors or other analog devices. These pins enable communication with SPI devices like sensors, displays, and memory chips.

Thanks for providing the great website. Hi Umar. After powering it with 3. My project can be found here: github. If you want to disable the interrupt of e. Datasheet is espressif. Hi, First of all, thank you for the detailed information you have given about the esp32 pinout. So, in reality, there are fewer possible interfaces for each device. It is strongly not recommended to reconfigure them for other application purposes. I wanted to take the time to thank you for these series of articles. Merci beaucoup! Best regards, Reply. Only on the ESP32 chip. The ADC analog to digital converter and DAC digital to analog converter features are assigned to specific static pins.

This can be very useful to control a relay, a thermostat, or any other device remotely.

I knew I had come on something good when I first found your pages a few years ago, and you keep the education going and going. Thanks for providing the great website. Boot message is not important for me. Here is a link to one? I would also avoid those without two onboard LEDs. Hi Many thanks. It took a while to realize what was going on, but I eventually moved to different pins. Excellent , thanks i have been confused with this issue since there are so m any pins and most have diffrenee possibilities. There are indeed two separate I2C interfaces. Log in to check out faster. ESP32 Datasheet. Are there any of the GPIO pins that can be read as a nibble or a byte for the purpose of reading jumpers or a switch? Great work!.. Hi, thanks for such a useful article.
