esp32 esp_timer_get_time 过多久回到0 esp32 时间 1. 之前的尝试(失败的尝试) 咸鱼买了3块ESP32开发板。背面写了NODEMCU v1.1,好像这玩意可以直接写lua,也可以刷Micropython写python,还可以用Arduino IDE写c。我想直接用官方库写C。 和乐鑫的这块开发板(ESP32-DevKitC)外观还挺像的(外观和引脚),可以参考这...

一旦定时器被启用,它的计数器就会开始运行。要启用计时器,请timer_init()使用counter_enset调用该函数true,或调用timer_start()。 您可以通过调用指定计时器的初始计数器值timer_set_counter_value()。 要检查计时器的当前值,请调用timer_get_counter_value()或timer_get_counter_time_sec()。
