# ampy replacement

We have been working on the next version of ampy which will solve various problems with the current system. Based on a new modular architecture, it makes adding device support and features very simple using plugins. It also aims to support coding over WiFi for supported devices. This should eliminate the need to have a wired connection and improve reliability as well.

[Here](https://github.com/curiouswala/ampy-2) is an alpha release please go ahead and play with it. Leave suggestions for a new name in the issue section. :)



## ampy



MicroPython Tool (ampy) - Utility to interact with a CircuitPython or MicroPython board over a serial connection.



Ampy is meant to be a simple command line tool to manipulate files and run code on a CircuitPython or

MicroPython board over its serial connection.

With ampy you can send files from your computer to the

board's file system, download files from a board to your computer, and even send a Python script

to a board to be executed.



Note that ampy by design is meant to be simple and does not support advanced interaction like a shell

or terminal to send input to a board.  Check out other MicroPython tools

like [rshell](https://github.com/dhylands/rshell)

or [mpfshell](https://github.com/wendlers/mpfshell) for more advanced interaction with boards.



## Installation



You can use ampy with either Python 2.7.x or 3.x and can install it easily from

Python's package index.  On MacOS or Linux, in a terminal run the following command (assuming

Python 3):



    pip3 install --user adafruit-ampy



On Windows, do:



    pip install adafruit-ampy



Note on some Linux and Mac OSX systems you might need to run as root with sudo:



    sudo pip3 install adafruit-ampy



If you don't have Python 3 then try using Python 2 with:



    pip install adafruit-ampy



Once installed verify you can run the ampy program and get help output:



    ampy --help



You should see usage information displayed like below:



    Usage: ampy [OPTIONS] COMMAND [ARGS]...



      ampy - Adafruit MicroPython Tool



      Ampy is a tool to control MicroPython boards over a serial connection.

      Using ampy you can manipulate files on the board's internal filesystem and

      even run scripts.



    Options:

      -p, --port PORT  Name of serial port for connected board.  [required]

      -b, --baud BAUD  Baud rate for the serial connection. (default 115200)

      -d, --delay DELAY Delay in seconds before entering RAW MODE (default 0)

      --help           Show this message and exit.



    Commands:

      get  Retrieve a file from the board.

      ls   List contents of a directory on the board.

      put  Put a file on the board.

      rm   Remove a file from the board.

      run  Run a script and print its output.



If you'd like to install from the Github source then use the standard Python

setup.py install (or develop mode):



    python3 setup.py install



Note to run the unit tests on Python 2 you must install the mock library:



    pip install mock



## Usage



Ampy is made to talk to a CircuitPython MicroPython board over its serial connection.  You will

need your board connected and any drivers to access it serial port installed.

Then for example to list the files on the board run a command like:



    ampy --port /dev/tty.SLAB_USBtoUART ls



You should see a list of files on the board's root directory printed to the

terminal.  Note that you'll need to change the port parameter to the name or path

to the serial port that the MicroPython board is connected to.



Other commands are available, run ampy with --help to see more information:



    ampy --help



Each subcommand has its own help, for example to see help for the ls command  run (note you

unfortunately must have a board connected and serial port specified):



    ampy --port /dev/tty.SLAB_USBtoUART ls --help



## Configuration



For convenience you can set an `AMPY_PORT` environment variable which will be used

if the port parameter is not specified.  For example on Linux or OSX:



    export AMPY_PORT=/dev/tty.SLAB_USBtoUART

    ampy ls



Or on Windows (untested) try the SET command:



    set AMPY_PORT=COM4

    ampy ls



Similarly, you can set `AMPY_BAUD` and `AMPY_DELAY` to control your baud rate and

the delay before entering RAW MODE.



To set these variables automatically each time you run `ampy`, copy them into a

file named `.ampy`:



```sh

# Example .ampy file

# Please fill in your own port, baud rate, and delay

AMPY_PORT=/dev/cu.wchusbserial1410

AMPY_BAUD=115200

# Fix for macOS users' "Could not enter raw repl"; try 2.0 and lower from there:

AMPY_DELAY=0.5

```



You can put the `.ampy` file in your working directory, one of its parents, or in

your home directory.
