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...

precision. Currently, the best I can do is esp_timer_get_time() which returns time with microsecond precision. I connected my board to an oscilloscope and found out that it takes around 1.29 us for the esp_timer_get_time() function to return time. Can I do better and with higher ...
I am looking to get time with nanoseconds precision. I know the function esp_timer_get_time() gives time in microseconds. I was hoping that I can modify it. Where can I find the source code/documentation to how it works.? ThanksESP...
