Connecting to Pycom using Ampy
- To connect to the Pycom enter the following command:
ampy -p /dev/ttyACM0 ls
- Commands need to be entered one at a time.
- This command list the main directory on the Pycom /flash
- All files on the Pycom are found within this directory.

- Use the get command to copy files from the pycom.
- The following commands serves as an example to get the boot.py file from the Pycom to the host computer.
- The get command will always overwrite files on the computer without warning!
ampy -p /dev/ttyACM0 get /flash/boot.py /home/pi/boot_backup.py
- The get command without a destination file name will print the contents of the file.
Put files onto the Pycom using Ampy
- Put files onto the Pycom with the command:
ampy -p /dev/ttyACM0 put /home/pi/test.py /flash/test.py
Run code using Ampy
- You can copy code to the Pycom and then run the code.
- Save the following code in a file named /home/pi/test.py
print('Hello world! I can count to 100:')
