hw_timer_t * timerBegin(uint8_t timer, uint16_t divider, bool countUp); 其三个参数是: 定时器x (一共4个,0-3) 分频数(基础时钟80MHZ,分频最大值为65536) 第三个是向上或向下计数标志 //然后我们用刚才定义的指针接收以下: timer = timerBegin(0,80,true); 1. 2. 3. 4. 5. 6. 7. ...
通常为80分频(设置APB时钟,ESP32主频80MHz),80则时间单位为1Mhz即1us,1000000us即1s。 countUp指定定时器是否为向上计数模式。设置为ture为向上计数,false为向下计数。 2.1.2 关联中断处理函数 void timerAttachInterrupt(hw_timer_t *timer, void (*fn)(void), bool edge) 1. timer指向已初始化的定时器指针...

ESP32 芯片包含两个硬件定时器组。每组有两个通用硬件定时器。它们都是基于 16 位预分频器和 64 位自动重载功能的向上/向下计数器的 64 位通用定时器。hw_timer_t * timerBegin(uint8_t num, uint16_t divider, bool countUp){} 参数:返回值: 返回一个计时器结构体指针 hw_timer_t * ...
