ESP32 Mac OS 开发教程

1. 安装串口驱动

下载驱动地址 https://cn.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads

下载mac对应的驱动

成功后执行 ls /dev/cu.*

显示/dev/cu.SLAB_USBtoUART 则是当前esp32的串口号也就是 port
/dev/cu.BLTH			/dev/cu.usbmodem2020_12_222
/dev/cu.Bluetooth-Incoming-Port	/dev/cu.usbserial-0001
/dev/cu.SLAB_USBtoUART
2.安装micropython

这里选择对应的固件 https://micropython.org/download/ESP32_GENERIC/

安装 https://github.com/espressif/esptool

# 执行下面命令，注意下载目录
esptool.py --chip esp32 --port /dev/cu.SLAB_USBtoUART --baud 460800 write_flash -z 0x1000 /Users/sss/Downloads/ESP32_GENERIC-20240222-v1.22.2.bin

3.也可以直接下载https://thonny.org/

点击thonny 运行->解释器->选择对应的 MicroPython(ESP32) 选择端口就是刚刚配置的串口 SLAB_USBtoUART 点击安装或更新MicroPython 则会自动安装成功
