Because default pins of UART1 such as GPIO9 and GPIO10 are internally connected to the SPI flash memory. Also, on some ESP32 boards, they are even exposed on the pinout headers. Hence, we can not use UART2 dire

There is RTC GPIO support on the ESP32. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The following GPIOs ca...

ESP32 GPIO Pins – Pinout ESP-IDF GPIO APIs for LED Blink Before we move ahead, let us discuss some important functions that are required for GPIO programming with regard to this project. ESP-IDF provides adriver/gpio.h librarythat provides helpful functions to control the digital input and ...
In the next step, the LED turns off for one second which means GPIO22 goes to an active low state The above two steps keep repeating as shown below: LED Blinking Connection Diagram As you can in the above pinout diagram of ESP32, we have a total of 36 GPIO pins, but we will be ...
https://randomnerdtutorials.com/esp32-pinout-reference-gpios/ 接入继电器之后,却不能控制其闭合或者断开(水位传感器也是,单独供电时,传感器信号没能正常传入ESP32) 原因分析: ESP32的GPIO引脚最高输出为3.3V电压,无法驱动继电器工作。继电器本质上依赖电压高低差而实现电磁的吸合以及断开 ...
PWM GPIO Pins Pulse Width Modulation (PWM) pins are crucial for motor control and LED brightness modulation applications. The ESP32 offers a range of PWM pins for such purposes. The ESP32 has 16 PWM-capable pins. All of them are those that have wiggly lines in the pinout diagram above. ...
or see attachment Please, if anyone can link me to the actual pinout diagrams, not the chip pinouts but the board pinouts, i would be greatly appreciative. thanks iomariYou do not have the required permissions to view the files attached to this post.becorey Posts: 92 Joined: Sat Mar 28...
