使用前需要先进行设定,设定的方法如下: 1.在Tool==>Serial Port里面选择Arduino的串口编号 2.在Tool==>Serial Monitor里面打开串口监视器 3.工具你程序的设定,在右下角的速度选择框里。
1.驱动没装好,2.board的串口没选对→_→ 这

将此草图上传到Arduino Uno开发板时,启动Serial Monitor工具。写“ 1”并发送。而且,现在您正在与Arduino Uno通信:) 现在,让我们使用上一个示例中的按钮。让我们读取数字输入引脚的状态,然后将其发送到串行通信,首先断开连接,然后使用按钮和Pull Down或Pull Up电阻。为此,我们将使用Arduino Uno,一个按钮和一个10k欧...
听起来你需要在状态改变后“去抖动”。当你把5V钩到引脚上时,它可能不会马上建立稳定的连接,所以它...
If you would like to make a PR for this, I guess I'd be OK to merge it, but I have no way of testing it as it seems unneeded no matter what version I try. Since the AVR cores also need a Serial Monitor, and they are unconditionally installed on the first run of the IDE, I...
Arduino serial monitor not showing any output when ESP32-S3 connected to USB Portby karunt » Sun Aug 11, 2024 2:21 pm Using Arduino IDE 2.3.2 on Windows 11 to upload the following sketch to an Adafruit Qualia ESP32-S3 board: ...
In ESP system settings, if I select UART0 as serial output, the project builds but the monitor has no output after starting the CPU scheduler (normally it says uart: queue free spaces: 20, but this does not appear). The program is still running, as evidenced by LEDs in a test program...
