From what you have written, the in-built LED of some ESP32 boards stays off when you run Code: Select all digitalWrite (blu_led, LOW); If you run Code: Select all digitalWrite (blu_led, HIGH); instead, do they turn on? If yes, then these boards are different from the generic ...
I need to turn on the LED and then read the strength of the reflection. The LED turns on fully within 8 microseconds, so in order to save energy, I turn it off once I get my data. To do all of this, I need precise control of when the LED is turned on and when the external ...
The red Power On LED should turn on. 初始设置 设置开发板,运行一个示例应用程序: 连接扬声器到 扬声器输出。也可选择连接耳机到 音频输出。 使用Micro-USB 数据线将 ESP32-LyraT-Mini 开发板的 两个 USB 端口 均与 PC 相连。 此时,绿色 待机指示灯 应亮起。假设电池未连接,那么红色 充电指示灯 将每隔几...
