esp32 - 如何修复 - 无法在 Esp32 中打开端口“/dev/cu.SLAB_USBtoUART”

问题描述

我正在尝试使用 Platform.io 将我的 Esp32 项目上传到 ESPWROOM32。

我尝试使用 Arduino 上传一个简单的代码并成功上传，这意味着问题不在于电缆或电路板。

但是当我切换到 Platform.io 并尝试上传时，它就会出现这个问题。

Uploading .pio\build\esp32doit-devkit-v1\firmware.bin
esptool.py v3.0
Serial port /dev/cu.SLAB_USBtoUART
Traceback (most recent call last):

    raise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError()))

解决方案

在您的platformio.ini文件中，将upload_port和monitor_port设置为连接ESP32的COM 端口。例如，

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
upload_port = COM5
monitor_port = COM5
monitor_speed = 115200
