ESP32是一款强大的开发板,通过使用Arduino编程语言,我们可以轻松地使用定时器功能来实现各种应用。本文将介绍如何在ESP32上使用定时器。 一、ESPTIMER定时器的介绍 1.1 定时器是什么单片机(Microcontroller)中的定时器是一种硬件模块,用于计时、计数和生成定时事件......

首先,我们需要使用gptimer_handle_t创建一个计时器句柄,方便我们操作计时器。笔者把句柄理解为指针,故初始化为NULL。 随后,利用函数gptimer_new_timer(const gptimer_config_t *config, gptimer_handle_t *ret_timer)实例化计时器,简而言之,第一个参数传入上文配置好的计时器配置结构体,第二个参数传入计时器句...

This is not explained in the two example applications in the latest Arduino-ESP32 Timer API either. Anyway, I was able to solve three compiler errors. 1. the removed API: Code: Select all timerAlarmWrite(hw_timer[timer_no], alarm_value, timer_reload); replaced with new API: Code: ...
