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 ...
SPIHD (GPIO12) and SPIWP (GPIO13) Pins are available to use as GPIO? In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC (Not Connected). However, in the table in section 2.3, they are designated as defau...
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...
ll also discuss how to use interrupts and write your interrupt service routine (ISR) for ESP32 external interrupt GPIO pins. Then, we’ll move to the Arduino Core libraries that implement drivers for the ESP32 interrupt pins and how to use its API functions, likeattachInterrupt(). Without ...

GPIOViewer Arduino Library to see live GPIO Pins on ESP32 boards - thelastoutpostworkshop/gpio_viewer
Example: To make GPIO22 as input and GPIO23 as output pinMode(22,INPUT_PULLUP); pinMode(23,OUTPUT); digitalWrite(23,HIGH); Analog Input Pins Note that only a subset of ADC pins and functions are exposed. First, the supplied drivers expose only ADC1. The board layout of the ESP32-De...
ESP32S3 GPIO restrictions : Strapping pin: GPIO0, GPIO3, GPIO45 and GPIO46 are strapping pins. SPI0/1: GPIO26-32 are usually used for SPI flash and PSRAM and not recommended for other uses. When using Octal Flash or Octal PSRAM or both, GPIO33~37 are connected to SPIIO4 ~ SPIIO...
