Why do we need this ESP32TimerInterrupt libraryFeaturesThis library enables you to use Interrupt from Hardware Timers on an ESP32-based board.As Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to 16 ISR-based Timers, while consuming ...
esp32-hal-timer.c 完整程序 这里我们用一个例子来演示一下,定时器计时周期设置为1秒,在中断函数中控制指示灯以1秒为周期闪烁。 登录后复制#defineLED_GPIO 4/* 创建硬件定时器 */hw_timer_t* timer =NULL;/* LED 状态 */byte led_state = LOW;voidIRAM_ATTRTimer0_Interrupt(){ ...
