SPI: Some fixes to docs and flag naming Kolban noticed the flags for a transaction are not named like the documentation states. The flags as mentioned in the docs are more consistent, so this MR renames them to that. Also some additions to the docs wrt the SPI signals Ref http://www.esp32.com/viewtopic.php?f=13&t=919&p=3976#p3976 and http://www.esp32.com/viewtopic.php?f=13&t=921&p=3975#p3975 See merge request !398 |

Examples
This directory contains a growing number of simple example projects for esp-idf. These are intended to show basic esp-idf functionality, and to provide you can use for your own projects.
Using Examples
Building examples is the same as building any other project:
-
Follow the setup instructions in the top-level esp-idf README.
-
Set
IDF_PATHenvironment variable to point to the path to the esp-idf top-level directory. -
Change into the directory of the example you'd like to build.
-
make menuconfigto configure the example. Most examples require a simple WiFi SSID & password via this configuration. -
maketo build the example. -
Follow the printed instructions to flash, or run
make flash.
Copying Examples
Each example is a standalone project. The examples do not have to be inside the esp-idf directory. You can copy an example directory to anywhere on your computer in order to make a copy that you can modify and work with.
The IDF_PATH environment variable is the only thing that connects the example to the rest of the esp-idf system.
If you're looking for a more bare-bones project to start from, try esp-idf-template.
Contributing Examples
If you have a new example you think we'd like, please consider sending it to us as a Pull Request.
Please read the esp-idf CONTRIBUTING.rst file which lays out general contribution rules.
In addition, here are some tips for creating good examples:
- A good example is documented and the basic options can be configured.
- A good example does not contain a lot of code. If there is a lot of generic code in the example, consider refactoring that code into a standalone component and then use the component's API in your example.
- Examples must be licensed under the Apache License 2.0 or (preferably for examples) if possible you can declare the example to be Public Domain / Creative Commons Zero.
