,就没有了.插上就又可以打印出来.程序我就不分析了.以后分析 ESP32使用不同的I2C引脚(更改默认I2C引脚)使用ESP32,你几乎可以将任何引脚设置为具有I2C功能,你只需要在代码中进行设置即可...当将ESP32与Arduino IDE搭配使用时,请使用 wire库以使用I2C与设备通信。...使用此库,你可以按以下方式初始化I2C: ...
In Arduino world there was a confusion about the flush() function. Some libraries implement it to discard the incoming bytes, reading them without storing. But decades is the flush() function in C, C++, Java used in conjunction with output buffering. To not to send every small piece of da...
Build this project and open a debugging session in STM32CubeIDE. Open your favorite serial terminal program and connect to the Nucleo’s COM port (baud rate of 115200, 8-N-1). You should be greeted by a query. Type out some answer and pressenter. Note that you will not be able to ...

His code is available for download from his site, and works perfectly in the Arduino IDE. The whole thing consists of some simple, easily ported code to implement a bare minimum bit-banged serial communication. This is output only, no feedback, and timing consists of just sending bits as ...
通过arduino,我必须为中继分配一个引脚,这样每当iBeacon接近时,它就会打开所有这些代码都会通过蓝牙检测arduino下面的代码帮助我建立esp32与iBeacon的连接,但现在我不知道如何继续使继电器在每次Ibeacon接近时激活,当我知道它何时移开时,继电器会通过蓝牙和arduino Ide关闭所有这些注意:我已经有了esp32库#包含<Arduino....
