So Easy MicroPython - ESP8266/ESP32 MCU File Management

Using ampy to manage the files on your MCU, for example ESP8266 or ESP32

Open the Terminal, you type

• pip install adafruit-ampy

type in ampy –help, if saw the message as screenshot means install successfully.

• ampy –help

As your coding done, just confirm your board and port first, plug-in your MCU, then ready to upload your file.

• ampy --port {your device port} put {path/xxx.py)

For example, the serial port of your MCU is /dev/cu.usbserial-11440, and filename is main.py on current directory.

Then, the command will be ampy --port /dev/cu.usbserial-11440 put main.py

How to verify if the file has been uploaded to the MCU, just using command "ls" to check.

• ampy --port {your device port} ls

Replace command "put" with "run", that all done

• ampy --port {your device port} run {path/xxx.py}

＊＊＊ If the file is either boot.py or main.py, they will be run automatically. So, just press the RST button to reboot it.

• Download file: ampy --port {your device port} get {path/xxx.py} {local driver path/xxx.py}
• Remove file: ampy --port {your device port} rm {path/xxx.py}
• Create directory: ampy --port {your device port} mkdir xxx
• Remove directory: ampy --port {your device port} rmdir xxx
• Reboot: ampy --port {your device port} reset
