So Easy MicroPython — ESP8266/ESP32 MCU File Management

Using ampy to manage the files of your MCU, for example on ESP8266, ESP32 or Raspberr Pi, …etc

Step 1: Install ampy

• pip install adafruit-ampy

Step 2: Verify ampy

• ampy — help

if you saw the message as screenshot means install successfully.

Step 3: Upload your file to MCU

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

As your coding done, confirm your board and port first, plug-in your MCU, then you are ready to upload your file, just using the commands above.

For example, if the serial port of your MCU is /dev/cu.usbserial-11440, and want to upload a file called main.py onto current directory.

Then, the command will be :

ampy — port /dev/cu.usbserial-11440 put main.py

Step 4: Check your file on MCU

• ampy — port {your device port} ls

Using command “ls” can check if the file has been uploaded to the MCU

Step 5: Execute the file

• ampy — port /dev/cu.usbserial-11440 run {path/xxx.py}

＊＊＊ If the file is either boot.py or main.py, it will be run automatically after start-up. So, you just need to press the RST button to reboot it. ＊＊＊

Step 6: Other commands

• 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

That’s all, so easy right ? Hope this helps !
