# DJITelloPy
## [中文文档 (Chinese version of this readme)](README_CN.md)
DJI Tello drone python interface using the official [Tello SDK](https://dl-cdn.ryzerobotics.com/downloads/tello/20180910/Tello%20SDK%20Documentation%20EN_1.3.pdf) and [Tello EDU SDK](https://dl-cdn.ryzerobotics.com/downloads/Tello/Tello%20SDK%202.0%20User%20Guide.pdf). This library has the following features:
- implementation of all tello commands
- easily retrieve a video stream
- receive and parse state packets
- control a swarm of drones
- support for python >= 3.6
Feel free to contribute!
## Install using pip
```
pip install djitellopy
```
For Linux distributions with both python2 and python3 (e.g. Debian, Ubuntu, ...) you need to run
```
pip3 install djitellopy
```
## Install in developer mode
Using the commands below you can install the repository in an _editable_ way. This allows you to modify the library and use the modified version as if you had installed it regularly.
```
git clone https://github.com/damiafuentes/DJITelloPy.git
cd DJITelloPy
pip install -e .
```
## Usage
### API Reference
See [djitellopy.readthedocs.io](https://djitellopy.readthedocs.io/en/latest/) for a full reference of all classes and methods available.
### Simple example
```python
from djitellopy import Tello
tello = Tello()
tello.connect()
tello.takeoff()
tello.move_left(100)
tello.rotate_counter_clockwise(90)
tello.move_forward(100)
tello.land()
```
### More examples
In the [examples](examples/) directory there are some code examples.
Comments in the examples are mostly in both english and chinese.
- [taking a picture](examples/take-picture.py)
- [recording a video](examples/record-video.py)
- [flying a swarm (multiple Tellos at once)](examples/simple-swarm.py)
- [simple controlling using your keyboard](examples/manual-control-opencv.py)
- [mission pad detection](examples/mission-pads.py)
- [fully featured manual control using pygame](examples/manual-control-pygame.py)
### Notes
- If you are using the `streamon` command and the response is `Unknown command` means you have to update the Tello firmware. That can be done through the Tello app.
- Mission pad detection and navigation is only supported by the Tello EDU.
- Bright environment is necessary for successful use of mission pads.
- Connecting to an existing wifi network is only supported by the Tello EDU.
- When connected to an existing wifi network video streaming is not available (TODO: needs confirmation with the new SDK3 `port` commands)

```
## 使用
### 查阅API
查看 [djitellopy.readthedocs.io](https://djitellopy.readthedocs.io/en/latest/) 以获取所有可用的类与方法。
### 简单示例
```python
from djitellopy import Tello
tello = Tello()
tello.connect()
tello.takeoff()
tello.move_left(100)
tello.rotate_counter_clockwise(90)
tello.move_forward(100)
tello.land()
```
### 更多示例
在 [示例](examples/) 有一些代码示例:

- [使用Pygame实现键盘控制飞机](examples/manual-control-pygame.py)
### 提示
- 如果你使用 ```streamon``` 命令时返回 ```Unknown command```你需要通过Tello app升级固件。
- 挑战卡识别与导航只支持Tello EDU
- 必须在明亮的环境下识别挑战卡
- 只有Tello EDU支持连接一个已存在的wifi
- 当连接一个已存在wifi时视频流不可用

Hello everyone, this is my 2D texture manager class for OpenGL using the FreeImage Library.
Requirements:
--------------------
OpenGL
STL map class
FreeImage (included)
Usage
--------------------
To load a texture, simply call the LoadTexture function:
TextureManager::Inst()->LoadTexture("img\\bg.jpg", BACKGROUND_IMAGE_ID);
This also binds the loaded texture as the current texture, so after calling it you may make any calls to glTexParameter you may need to specify the properties of the texture.
When you are rendering, just call the TextureManager's BindImage function instead of glBindImage:
TextureManager::Inst()->BindImage(BACKGROUND_IMAGE_ID);
and then do your rendering as normal.
--------------------
Feel free to distribute this as you like, but mind the FreeImage licence included in license-fi.txt, and please don't take credit for my code. If you modify it, be sure to mention me (Ben English) somewhere.
Please send any comments or suggestions to me at benjamin.english@oit.edu
Thanks to Herve Drolon for the FreeImage library, I've found it to be very useful!

Loads a bitmap into memory. On entry it is assumed that
the bitmap to be loaded is of the correct type. If the bitmap
is of an incorrect type, the plugin might not gracefully fail but
crash or enter an endless loop. It is also assumed that all
the bitmap data is available at one time. If the bitmap is not complete,
for example because it is being downloaded while loaded, the plugin
might also not gracefully fail.
The Load function has the following parameters:
The first parameter (FreeImageIO *io) is a structure providing
function pointers in order to make use of FreeImage's IO redirection. Using
FreeImage's file i/o functions instead of standard ones it is garantueed
that all bitmap types, both current and future ones, can be loaded from
memory, file cabinets, the internet and more. The second parameter (fi_handle handle)
is a companion of FreeImageIO and can be best compared with the standard FILE* type,
in a generalized form.
The third parameter (int page) indicates wether we will be loading a certain page
in the bitmap or if we will load the default one. This parameter is only used if
the plugin supports multi-paged bitmaps, e.g. cabinet bitmaps that contain a series
of images or pages. If the plugin does support multi-paging, the page parameter
can contain either a number higher or equal to 0 to load a certain page, or -1 to
load the default page. If the plugin does not support multi-paging,
the page parameter is always -1.
The fourth parameter (int flags) manipulates the load function to load a bitmap
in a certain way. Every plugin has a different flag parameter with different meanings.
The last parameter (void *data) can contain a special data block used when
the file is read multi-paged. Because not every plugin supports multi-paging
not every plugin will use the data parameter and it will be set to NULL.However,
when the plugin does support multi-paging the parameter contains a pointer to a
block of data allocated by the Open function.

number that the plugin may use to show plugin specific warning messages
or other information to the user. The plugin number
is generated by FreeImage and can differ everytime the plugin is
initialised.
If you want to create your own plugin you have to take some
rules into account. Plugin functions have to be compiled
__stdcall using the multithreaded c runtime libraries. Throwing
exceptions in plugin functions is allowed, as long as those exceptions
are being caught inside the same plugin. It is forbidden for a plugin
function to directly call FreeImage functions or to allocate memory
and pass it to the main DLL. Exception to this rule is the special file data
block that may be allocated the Open function. Allocating a FIBITMAP inside a
plugin can be using the function allocate_proc in the FreeImage structure,
which will allocate the memory using the DLL's c runtime library.

Using the FreeImage library with the MinGW Compiler Suite
=====================================================================
This file describes how to use the precompiled FreeImage library
FreeImage.dll with the MinGW port of the GNU Compiler Collection
(GCC), how to build this library from source using MinGW and how
to use this MinGW-built library with Microsoft Visual Studio.
Contents:
I. Prerequisites
1. Using the precompiled FreeImage library with MinGW
2. Building the FreeImage library with MinGW
3. Using the MinGW FreeImage library with Microsoft Visual Studio
4. Useful links
---------------------------------------------------------------------
I. Prerequisites
=====================================================================
The procedures described in this document have been developed and
tested using the following free tools:
1. MinGW GCC Version 4.4.0 (Core and C++ including required libs)
2. MinGW GNU Binutils Version 2.19.1
3. MinGW GNU Make Version 3.81-20080326-3
4. MinGW Runtime Version 3.15.2
5. MinGW API for MS-Windows Version 3.13
6. GnuWin32 Package CoreUtils Version 5.3.0 (only for building)
7. GnuWin32 Package Sed Version 4.2 (only for creating the GCC
import library)*
* Sed is only needed to create a GCC-native import library from
the MSVC import library FreeImage.lib. However, since MinGW now
supports linking against MSVC lib files, this process seems to
be obsolete. See section 1.
Basically, no version dependent capabilities are used so, this
should also work with older versions of the tools mentioned above.
Similarly, the GnuWin32 packages (which I just prefer over MSYS)
could likely be replaced by a properly installed MSYS environment.
Furthermore, the following preconditions should be met:
1. The folders 'bin' under both the MinGW and the GnuWin32
installation directory should have been added to the PATH
environment variable. Likely it is best adding these
directories permanently to PATH through the System
Properties dialog on the Control Panel.
2. The MinGW Make package only provides a 'mingw32-make.exe'
executable. There is no alias 'make.exe'. However, make is
preconfigured to use 'make' as the default $(MAKE) command.
This seems to be a bug in the MinGW GNU Make distribution.
Thus, a copy of 'mingw32-make.exe' named 'make.exe' should
be placed into MinGW's 'bin' directory.
---------------------------------------------------------------------
1. Using the precompiled FreeImage library with MinGW
=====================================================================
When using functions from C/C++, that reside in a DLL, the linker
needs a so called import library, which specifies, how to
dynamically link these external functions during runtime. However,
different linkers use different types or formats of these import
libraries.
Since the precompiled FreeImage library was build with Microsoft
Visual Studio, in the past, some extra work was required to use it
from MinGW. An import library, that was compatible with GNU ld,
must have been created first.
However, for several MinGW versions, the GNU linker ld also
supports linking against Microsoft Visual C++ import libraries
directly. So, this effectively makes any circulating HOWTO's on
how to create a GCC-compatible import library from a MSVC lib file
more or less obsolete. Additionally, MinGW does not require the
GCC/Linux usual lib prefix for libraries, so linking with MinGW
against the precompiled FreeImage DLL is as easy as with MSVC:
1.) Open a DOS shell (run application cmd.exe)
2.) Ensure, that the 'bin' folder of MinGW is added to the PATH
environment variable (see Prerequisites).
3.) Link directly against the supplied lib file:
C:\>gcc -oFreeImageTest.exe FreeImageTest.c -lFreeImage
Nonetheless, for the sake of completeness, the following steps
describe how to create a native GCC import library:
1.) Open a DOS shell (run application cmd.exe)
2.) Ensure, that the 'bin' folders of both MinGW and GnuWin32 are
added to the PATH environment variable (see Prerequisites).
3.) Create a .def file 'libfreeimage.def', that contains all symbols
exported by the FreeImage library:
C:\>pexports FreeImage.dll | sed "s/^_//" > libfreeimage.def
4.) Create the GCC compatible import library 'libfreeimage.a':
C:\>dlltool --add-underscore -d libfreeimage.def -l libfreeimage.a
5.) Use this library to link against with GCC:
C:\>gcc -oFreeImageTest.exe FreeImageTest.c -lfreeimage
---------------------------------------------------------------------
2. Building the FreeImage library with MinGW
=====================================================================
You *do not* need to have any other third party library (like
libjpeg, libpng, libtiff, libmng and zlib and others) installed on
your system in order to compile and use the library. FreeImage uses
its own versions of these libraries. This way, you can be sure that
FreeImage will always use the latest and properly tested versions
of of these third party libraries.
In order to build the FreeImage library under Windows with MinGW
(GCC), ensure that all the prerequisites mentioned above are met.
The MinGW makefile aims to build a Windows DLL, that differs as
least as possible from the precompiled library that comes with the
FreeImage distribution. Thus, the build process also includes the
DLL version resource as well as the __stdcall attribute for all the
exported functions, including the MSVC-like function decorations
_FuncName@nn.
When building the FreeImage DLL, of course, an import library is
generated, too. However, this input library is not in GCC's native
format, but in MSVC lib format, which makes it usable from both
MinGW and Microsoft Visual Studio with no further processing.
The MinGW makefile can also be used to build a static library.
However, due to the different function export attributes needed
for both the dynamic and the shared library (DLL), this requires
a separate invocation of make, which in turn needs to rebuild every
source file after switching from dynamic to static and vice versa.
So, a 'make clean' is required each time, the library type is
changed.
The type of library to build is specified by a variable named
FREEIMAGE_LIBRARY_TYPE, which may either be set directly in the
Makefile.mingw near line 18 or may be specified as an environment
variable. This variable may either take SHARED or STATIC to build
a dynamic link library (DLL) or a static library respectively.
Since this value is used to dynamically form the actual make target
internally, only uppercase values are valid. Defaults to SHARED.
The MinGW makefile also supports the 'install' target. However,
this only copies the FreeImage dynamic link library (DLL) from the
Dist folder into the %SystemRoot%\system32 folder. So, invoking this
target only makes sense, if the DLL has been built before.
Since there is neither a common system wide 'include' nor a 'lib'
directory available under Windows, the FreeImage header file
FreeImage.h as well as both the static library and the DLL import
library FreeImage.lib just remain in the 'Dist' folder.
The following procedure creates the FreeImage dynamic link library
(DLL) from the sources, installs it and also creates a static
FreeImage library:
1.) Open a DOS shell (run application cmd.exe)
2.) Ensure, that the 'bin' folders of both MinGW and GnuWin32 are
added to the PATH environment variable (see Prerequisites).
3.) Create the FreeImage dynamic link library (DLL):
C:\>make
4.) Install the FreeImage dynamic link library (DLL):
C:\>make install
5.) Clean all files produced by the recent build process:
C:\>make clean
6.) Create a static FreeImage library:
C:\>set FREEIMAGE_LIBRARY_TYPE=STATIC
C:\>make
You should be able to link progams with the -lFreeImage option
after the shared library is compiled and installed. You can also
link statically against FreeImage.a from MinGW.
---------------------------------------------------------------------
3. Using the MinGW FreeImage library with Microsoft Visual Studio
=====================================================================
Since the MinGW makefile creates an import library in MSVC's lib
format, the produced shared library (DLL) can be used from both
MinGW and Microsoft Visual Studio with no further adaption. Just
link to the import library FreeImage.lib from either MinGW or
Microsoft Visual Studio.
