I am trying to configure GPIO_NUM_33 as digital output, below the code: Code: Untitled.c Select all gpio_set_direction(GPIO_NUM_33, GPIO_MODE_OUTPUT); while (1) { vTaskDelay(500 / portTICK_PERIOD_MS); /* Toggl

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...

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 ...
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); ...

我们将对 ESP32 进行编程,使其充当 BLE 客户端,并不断扫描 BLE 设备;如果我们在范围内找到健身带,我们将尝试连接到它,如果连接成功,我们可以通过切换ESP32上的一个GPIO引脚来触发灯泡。该方法是可靠的,因为每个BLE服务器(健身带)将具有唯一的硬件ID,因此没有两个BLE服务器设备是相同的。有趣的对吧?!!!现在,...
