I am trying to configure GPIO_NUM_33 as digital output, below the code: Code: Untitled.cSelect all gpio_set_direction(GPIO_NUM_33, GPIO_MODE_OUTPUT);while(1) { vTaskDelay(500/ portTICK_PERIOD_MS);/* Toggle the LED state */s_led_state = !s_led_state; gpio_set_level(GPIO_NUM_...

I've designed a custom ESP32S3 board for controlling some motors. In testing my GPIO, I've found that I can't set some of my GPIO as outputs. I use GPIOS: 2 - Output 4 - No output 5 - No output 8 - Output 9 - Output 18 - No output 37 - Output (I have some others ...

GPIO19 GPIO21 GPIO22 GPIO23 Pins without internal pull up GPIO13 GPIO25 GPIO26 GPIO27 GPIO32 GPIO33 In arduino to use these pins you can simply use common commands Example: To make GPIO22 as input and GPIO23 as output pinMode(22,INPUT_PULLUP); ...
一、GPIO 中断使用简析 1、中断触发方式 ESP32 Arduino 有以下四种触发方式: LOW 低电平触发 CHANGE 电平变化 RISING 上升沿触发 FALLING 下降沿触发 HIGH 高电平触发 2、配置中断 在定义中断函数后,需要在 setup 函数配置中断函数 // interrupt=中断通道编号,function=中断函数,mode=中断触发模式 ...
