In this tutorial, you’ll learn how to use ESP32 interrupt pins in Arduino Core. We’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...
5. ADC On the ESP32 ADC functionality is available on Pins 32-39. Note that, when using the default configuration, input voltages on the ADC pin must be between 0.0v and 1.0v (anything above 1.0v will just read as 4095). Attenuation must be applied in order to increase this usable vo...
local getGPIO7=pins.setup(7)–配置GPIO7,输入模式, 可以通过getGPIO7()获取IO的电平为0还是1 3、中断模式 假设设置GPIO7为中断模式,只需要 随意定义一个变量,如 local getGPIO7=pins.setup(7,interrupt_re)–配置GPIO7,输入模式,interrupt_re为中断处理函数,中断处理函数随便写 如下 function interrupt_re(m...

ESP32-C3 VScode开发环境搭建(基于乐鑫官方ESP-IDF——Windows和Ubuntu双环境) 1、GPIO示例测试 在开发板上面,我们预留了2个按键,一个普通按键接口 GPIO7: 此外还有一个用于观察启动模式的按键 GPIO9 (设计目的是可以根据按下与不按下观察 ESP32-C3的不同启动模式,同时检测一下芯片启动后是否能够当做普通 GPIO ...
