Distribution packages, package management, and deploying applications
=====================================================================
Just as the "big" Python, MicroPython supports creation of "third party"
packages, distributing them, and easily installing them in each user's
environment. This chapter discusses how these actions are achieved.
Some familiarity with Python packaging is recommended.
Overview
--------
Steps below represent a high-level workflow when creating and consuming
packages:
1. Python modules and packages are turned into distribution package
archives, and published at the Python Package Index (PyPI).
2. `upip` package manager can be used to install a distribution package
on a `MicroPython port` with networking capabilities (for example,
on the Unix port).
3. For ports without networking capabilities, an "installation image"
can be prepared on the Unix port, and transferred to a device by
suitable means.
4. For low-memory ports, the installation image can be frozen as the
bytecode into MicroPython executable, thus minimizing the memory
storage overheads.
The sections below describe this process in details.
Distribution packages
---------------------
Python modules and packages can be packaged into archives suitable for
transfer between systems, storing at the well-known location (PyPI),
and downloading on demand for deployment. These archives are known as
*distribution packages* (to differentiate them from Python packages
(means to organize Python source code)).
The MicroPython distribution package format is a well-known tar.gz
format, with some adaptations however. The Gzip compressor, used as
an external wrapper for TAR archives, by default uses 32KB dictionary
size, which means that to uncompress a compressed stream, 32KB of
contguous memory needs to be allocated. This requirement may be not
satisfiable on low-memory devices, which may have total memory available
less than that amount, and even if not, a contiguous block like that
may be hard to allocate due to memory fragmentation. To accommodate
these constraints, MicroPython distribution packages use Gzip compression
with the dictionary size of 4K, which should be a suitable compromise
with still achieving some compression while being able to uncompressed
even by the smallest devices.
Besides the small compression dictionary size, MicroPython distribution
packages also have other optimizations, like removing any files from
the archive which aren't used by the installation process. In particular,
`upip` package manager doesn't execute ``setup.py`` during installation
(see below), and thus that file is not included in the archive.
At the same time, these optimizations make MicroPython distribution
packages not compatible with `CPython`'s package manager, ``pip``.
This isn't considered a big problem, because:
1. Packages can be installed with `upip`, and then can be used with
CPython (if they are compatible with it).
2. In the other direction, majority of CPython packages would be
incompatible with MicroPython by various reasons, first of all,
the reliance on features not implemented by MicroPython.
Summing up, the MicroPython distribution package archives are highly
optimized for MicroPython's target environments, which are highly
resource constrained devices.
``upip`` package manager
------------------------
MicroPython distribution packages are intended to be installed using
the `upip` package manager. `upip` is a Python application which is
usually distributed (as frozen bytecode) with network-enabled
`MicroPython ports <MicroPython port>`. At the very least,
`upip` is available in the `MicroPython Unix port`.
On any `MicroPython port` providing `upip`, it can be accessed as
following::
import upip
upip.help()
upip.install(package_or_package_list, [path])
Where *package_or_package_list* is the name of a distribution
package to install, or a list of such names to install multiple
packages. Optional *path* parameter specifies filesystem
location to install under and defaults to the standard library
location (see below).
An example of installing a specific package and then using it::
>>> import upip
>>> upip.install("micropython-pystone_lowmem")
[...]
>>> import pystone_lowmem
>>> pystone_lowmem.main()
Note that the name of Python package and the name of distribution
package for it in general don't have to match, and oftentimes they
don't. This is because PyPI provides a central package repository
for all different Python implementations and versions, and thus
distribution package names may need to be namespaced for a particular
implementation. For example, all packages from `micropython-lib`
follow this naming convention: for a Python module or package named
``foo``, the distribution package name is ``micropython-foo``.
For the ports which run MicroPython executable from the OS command
prompts (like the Unix port), `upip` can be (and indeed, usually is)
run from the command line instead of MicroPython's own REPL. The
commands which corresponds to the example above are::
micropython -m upip -h
micropython -m upip install [-p <path>] <packages>...
micropython -m upip install micropython-pystone_lowmem
[TODO: Describe installation path.]
Cross-installing packages
-------------------------
For `MicroPython ports <MicroPython port>` without native networking
capabilities, the recommend process is "cross-installing" them into a
"directory image" using the `MicroPython Unix port`, and then
transferring this image to a device by suitable means.
Installing to a directory image involves using ``-p`` switch to `upip`::
micropython -m upip install -p install_dir micropython-pystone_lowmem
After this command, the package content (and contents of every depenency
packages) will be available in the ``install_dir/`` subdirectory. You
would need to transfer contents of this directory (without the
``install_dir/`` prefix) to the device, at the suitable location, where
it can be found by the Python ``import`` statement (see discussion of
the `upip` installation path above).
Cross-installing packages with freezing
---------------------------------------
For the low-memory `MicroPython ports <MicroPython port>`, the process
described in the previous section does not provide the most efficient
resource usage,because the packages are installed in the source form,
so need to be compiled to the bytecome on each import. This compilation
requires RAM, and the resulting bytecode is also stored in RAM, reducing
its amount available for storing application data. Moreover, the process
above requires presence of the filesystem on a device, and the most
resource-constrained devices may not even have it.
The bytecode freezing is a process which resolves all the issues
mentioned above:
* The source code is pre-compiled into bytecode and store as such.
* The bytecode is stored in ROM, not RAM.
* Filesystem is not required for frozen packages.
Using frozen bytecode requires building the executable (firmware)
for a given `MicroPython port` from the C source code. Consequently,
the process is:
1. Follow the instructions for a particular port on setting up a
toolchain and building the port. For example, for ESP8266 port,
study instructions in ``ports/esp8266/README.md`` and follow them.
Make sure you can build the port and deploy the resulting
executable/firmware successfully before proceeding to the next steps.
2. Build `MicroPython Unix port` and make sure it is in your PATH and
you can execute ``micropython``.
3. Change to port's directory (e.g. ``ports/esp8266/`` for ESP8266).
4. Run ``make clean-frozen``. This step cleans up any previous
modules which were installed for freezing (consequently, you need
to skip this step to add additional modules, instead of starting
from scratch).
5. Run ``micropython -m upip install -p modules <packages>...`` to
install packages you want to freeze.
6. Run ``make clean``.
7. Run ``make``.
After this, you should have the executable/firmware with modules as
the bytecode inside, which you can deploy the usual way.
Few notes:
1. Step 5 in the sequence above assumes that the distribution package
is available from PyPI. If that is not the case, you would need
to copy Python source files manually to ``modules/`` subdirectory
of the port port directory. (Note that upip does not support
installing from e.g. version control repositories).
2. The firmware for baremetal devices usually has size restrictions,
so adding too many frozen modules may overflow it. Usually, you
would get a linking error if this happens. However, in some cases,
an image may be produced, which is not runnable on a device. Such
cases are in general bugs, and should be reported and further
investigated. If you face such a situation, as an initial step,
you may want to decrease the amount of frozen modules included.
Creating distribution packages
------------------------------
Distribution packages for MicroPython are created in the same manner
as for CPython or any other Python implementation, see references at
the end of chapter. Setuptools (instead of distutils) should be used,
because distutils do not support dependencies and other features. "Source
distribution" (``sdist``) format is used for packaging. The post-processing
discussed above, (and pre-processing discussed in the following section)
is achieved by using custom ``sdist`` command for setuptools. Thus, packaging
steps remain the same as for the standard setuptools, the user just
needs to override ``sdist`` command implementation by passing the
appropriate argument to ``setup()`` call::
from setuptools import setup
import sdist_upip
setup(
...,
cmdclass={'sdist': sdist_upip.sdist}
)
The sdist_upip.py module as referenced above can be found in
`micropython-lib`:
https://github.com/micropython/micropython-lib/blob/master/sdist_upip.py
Application resources
---------------------
A complete application, besides the source code, oftentimes also consists
of data files, e.g. web page templates, game images, etc. It's clear how
to deal with those when application is installed manually - you just put
those data files in the filesystem at some location and use the normal
file access functions.
The situation is different when deploying applications from packages - this
is more advanced, streamlined and flexible way, but also requires more
advanced approach to accessing data files. This approach is treating
the data files as "resources", and abstracting away access to them.
Python supports resource access using its "setuptools" library, using
``pkg_resources`` module. MicroPython, following its usual approach,
implements subset of the functionality of that module, specifically
``pkg_resources.resource_stream(package, resource)`` function.
The idea is that an application calls this function, passing a
resource identifier, which is a relative path to data file within
the specified package (usually top-level application package). It
returns a stream object which can be used to access resource contents.
Thus, the ``resource_stream()`` emulates interface of the standard
`open()` function.
Implementation-wise, ``resource_stream()`` uses file operations
underlyingly, if distribution package is install in the filesystem.
However, it also supports functioning without the underlying filesystem,
e.g. if the package is frozen as the bytecode. This however requires
an extra intermediate step when packaging application - creation of
"Python resource module".
The idea of this module is to convert binary data to a Python bytes
object, and put it into the dictionary, indexed by the resource name.
This conversion is done automatically using overridden ``sdist`` command
described in the previous section.
Let's trace the complete process using the following example. Suppose
your application has the following structure::
my_app/
__main__.py
utils.py
data/
page.html
image.png
``__main__.py`` and ``utils.py`` should access resources using the
following calls::
import pkg_resources
pkg_resources.resource_stream(__name__, "data/page.html")
pkg_resources.resource_stream(__name__, "data/image.png")
You can develop and debug using the `MicroPython Unix port` as usual.
When time comes to make a distribution package out of it, just use
overridden "sdist" command from sdist_upip.py module as described in
the previous section.
This will create a Python resource module named ``R.py``, based on the
files declared in ``MANIFEST`` or ``MANIFEST.in`` files (any non-``.py``
file will be considered a resource and added to ``R.py``) - before
proceeding with the normal packaging steps.
Prepared like this, your application will work both when deployed to
filesystem and as frozen bytecode.
If you would like to debug ``R.py`` creation, you can run::
python3 setup.py sdist --manifest-only
Alternatively, you can use tools/mpy_bin2res.py script from the
MicroPython distribution, in which can you will need to pass paths
to all resource files::
mpy_bin2res.py data/page.html data/image.png

MicroPython port to the ESP32
=============================
This is an experimental port of MicroPython to the Espressif ESP32
microcontroller. It uses the ESP-IDF framework and MicroPython runs as
a task under FreeRTOS.
Supported features include:
- REPL (Python prompt) over UART0.
- 16k stack for the MicroPython task and 96k Python heap.
- Many of MicroPython's features are enabled: unicode, arbitrary-precision
integers, single-precision floats, complex numbers, frozen bytecode, as
well as many of the internal modules.
- Internal filesystem using the flash (currently 2M in size).
- The machine module with GPIO, UART, SPI, software I2C, ADC, DAC, PWM,
TouchPad, WDT and Timer.
- The network module with WLAN (WiFi) support.
Development of this ESP32 port was sponsored in part by Microbric Pty Ltd.
Setting up the toolchain and ESP-IDF
------------------------------------
There are two main components that are needed to build the firmware:
- the Xtensa cross-compiler that targets the CPU in the ESP32 (this is
different to the compiler used by the ESP8266)
- the Espressif IDF (IoT development framework, aka SDK)
The ESP-IDF changes quickly and MicroPython only supports a certain version. The
git hash of this version can be found by running `make` without a configured
`ESPIDF`. Then you can fetch only the given esp-idf using the following command:
$ git clone https://github.com/espressif/esp-idf.git
$ git checkout <Current supported ESP-IDF commit hash>
$ git submodule update --init --recursive
The binary toolchain (binutils, gcc, etc.) can be installed using the following
guides:
* [Linux installation](https://esp-idf.readthedocs.io/en/latest/get-started/linux-setup.html)
* [MacOS installation](https://esp-idf.readthedocs.io/en/latest/get-started/macos-setup.html)
* [Windows installation](https://esp-idf.readthedocs.io/en/latest/get-started/windows-setup.html)
If you are on a Windows machine then the
[Windows Subsystem for Linux](https://msdn.microsoft.com/en-au/commandline/wsl/install_guide)
is the most efficient way to install the ESP32 toolchain and build the project.
If you use WSL then follow the
[Linux guidelines](https://esp-idf.readthedocs.io/en/latest/get-started/linux-setup.html)
for the ESP-IDF instead of the Windows ones.
The Espressif ESP-IDF instructions above only install pyserial for Python 2,
so if you're running Python 3 or a non-system Python you'll also need to
install `pyserial` (or `esptool`) so that the Makefile can flash the board
and set parameters:
```bash
$ pip install pyserial
```
Once everything is set up you should have a functioning toolchain with
prefix xtensa-esp32-elf- (or otherwise if you configured it differently)
as well as a copy of the ESP-IDF repository. You will need to update your `PATH`
environment variable to include the ESP32 toolchain. For example, you can issue
the following commands on (at least) Linux:
$ export PATH=$PATH:$HOME/esp/crosstool-NG/builds/xtensa-esp32-elf/bin
You can put this command in your `.profile` or `.bash_login`.
You then need to set the `ESPIDF` environment/makefile variable to point to
the root of the ESP-IDF repository. You can set the variable in your PATH,
or at the command line when calling make, or in your own custom `makefile`.
The last option is recommended as it allows you to easily configure other
variables for the build. In that case, create a new file in the esp32
directory called `makefile` and add the following lines to that file:
```
ESPIDF = <path to root of esp-idf repository>
#PORT = /dev/ttyUSB0
#FLASH_MODE = qio
#FLASH_SIZE = 4MB
#CROSS_COMPILE = xtensa-esp32-elf-
#CONFIG_SPIRAM_SUPPORT = 1
include Makefile
```
Be sure to enter the correct path to your local copy of the IDF repository
(and use `$(HOME)`, not tilde, to reference your home directory).
If your filesystem is case-insensitive then you'll need to use `GNUmakefile`
instead of `makefile`.
If the Xtensa cross-compiler is not in your path you can use the
`CROSS_COMPILE` variable to set its location. Other options of interest
are `PORT` for the serial port of your esp32 module, and `FLASH_MODE`
(which may need to be `dio` for some modules)
and `FLASH_SIZE`. See the Makefile for further information.
Building the firmware
---------------------
The MicroPython cross-compiler must be built to pre-compile some of the
built-in scripts to bytecode. This can be done by (from the root of
this repository):
```bash
$ make -C mpy-cross
```
The ESP32 port has a dependency on Berkeley DB, which is an external
dependency (git submodule). You'll need to have git initialize that
module using the commands:
```bash
$ git submodule init lib/berkeley-db-1.xx
$ git submodule update
```
Then to build MicroPython for the ESP32 run:
```bash
$ cd ports/esp32
$ make
```
This will produce binary firmware images in the `build/` subdirectory
(three of them: bootloader.bin, partitions.bin and application.bin).
To flash the firmware you must have your ESP32 module in the bootloader
mode and connected to a serial port on your PC. Refer to the documentation
for your particular ESP32 module for how to do this. The serial port and
flash settings are set in the `Makefile`, and can be overridden in your
local `makefile`; see above for more details.
You will also need to have user permissions to access the /dev/ttyUSB0 device.
On Linux, you can enable this by adding your user to the `dialout` group,
and rebooting or logging out and in again.
```bash
$ sudo adduser <username> dialout
```
If you are installing MicroPython to your module for the first time, or
after installing any other firmware, you should first erase the flash
completely:
```bash
$ make erase
```
To flash the MicroPython firmware to your ESP32 use:
```bash
$ make deploy
```
This will use the `esptool.py` script (provided by ESP-IDF) to download the
binary images.
Getting a Python prompt
-----------------------
You can get a prompt via the serial port, via UART0, which is the same UART
that is used for programming the firmware. The baudrate for the REPL is
115200 and you can use a command such as:
```bash
$ picocom -b 115200 /dev/ttyUSB0
```
Configuring the WiFi and using the board
----------------------------------------
The ESP32 port is designed to be (almost) equivalent to the ESP8266 in
terms of the modules and user-facing API. There are some small differences,
notably that the ESP32 does not automatically connect to the last access
point when booting up. But for the most part the documentation and tutorials
for the ESP8266 should apply to the ESP32 (at least for the components that
are implemented).
See http://docs.micropython.org/en/latest/esp8266/esp8266/quickref.html for
a quick reference, and http://docs.micropython.org/en/latest/esp8266/esp8266/tutorial/intro.html
for a tutorial.
The following function can be used to connect to a WiFi access point (you can
either pass in your own SSID and password, or change the defaults so you can
quickly call `wlan_connect()` and it just works):
```python
def wlan_connect(ssid='MYSSID', password='MYPASS'):
import network
wlan = network.WLAN(network.STA_IF)
if not wlan.active() or not wlan.isconnected():
wlan.active(True)
print('connecting to:', ssid)
wlan.connect(ssid, password)
while not wlan.isconnected():
pass
print('network config:', wlan.ifconfig())
```
Note that some boards require you to configure the WiFi antenna before using
the WiFi. On Pycom boards like the LoPy and WiPy 2.0 you need to execute the
following code to select the internal antenna (best to put this line in your
boot.py file):
```python
import machine
antenna = machine.Pin(16, machine.Pin.OUT, value=0)
```
Troubleshooting
---------------
* Continuous reboots after programming: Ensure FLASH_MODE is correct for your
board (e.g. ESP-WROOM-32 should be DIO). Then perform a `make clean`, rebuild,
redeploy.

# ULP
To compile binarys for the ulp you need the ulp toolkit. Download it from https://github.com/espressif/binutils-esp32ulp/wiki#downloads
Then extract it, then add ```esp32ulp-elf-binutils/bin``` to your PATH
## Example Makefile
```make
ULP_S_SOURCES := main.S
ULP_APP_NAME := test
ULP_LD_SCRIPT := esp32.ulp.ld
SRC_PATH := src
BUILD_PATH := build
include $(ESPIDF)/components/ulp/Makefile.projbuild
