How to build PlatformIO based project
=====================================
1. `Install PlatformIO Core <http://docs.platformio.org/page/core.html>`_
2. Download `development platform with examples <https://github.com/platformio/platform-espressif32/archive/develop.zip>`_
3. Extract ZIP archive
4. Run these commands:
.. code-block:: bash
# Change directory to example
> cd platform-espressif32/examples/espidf-ulp-adc
# Build project
> platformio run
# Upload firmware
> platformio run --target upload
# Build specific environment
> platformio run -e esp32dev
# Upload firmware for the specific environment
> platformio run -e esp32dev --target upload
# Clean build files
> platformio run --target clean

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
and a contents of `src/main.c`:
```
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
```
PlatformIO Library Dependency Finder will find automatically dependent
libraries scanning project source files.

This directory is intended for PIO Unit Testing and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

This file contains assembly code which runs on the ULP.
ULP wakes up to run this code at a certain period, determined by the values
in SENS_ULP_CP_SLEEP_CYCx_REG registers. On each wake up, the program
measures input voltage on the given ADC channel 'adc_oversampling_factor'
times. Measurements are accumulated and average value is calculated.
Average value is compared to the two thresholds: 'low_thr' and 'high_thr'.
If the value is less than 'low_thr' or more than 'high_thr', ULP wakes up
the chip from deep sleep.

How to build PlatformIO based project
=====================================
1. `Install PlatformIO Core <http://docs.platformio.org/page/core.html>`_
2. Download `development platform with examples <https://github.com/platformio/platform-espressif32/archive/develop.zip>`_
3. Extract ZIP archive
4. Run these commands:
.. code-block:: bash
# Change directory to example
> cd platform-espressif32/examples/espidf-ulp-pulse
# Build project
> platformio run
# Upload firmware
> platformio run --target upload
# Build specific environment
> platformio run -e esp32dev
# Upload firmware for the specific environment
> platformio run -e esp32dev --target upload
# Clean build files
> platformio run --target clean

This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in `src` folder
by including it, with the C preprocessing directive `#include'.
```src/main.c
#include "header.h"
int main (void)
{
...
}
```
Including a header file produces the same results as copying the header file
into each source file that needs it. Such copying would be time-consuming
and error-prone. With a header file, the related declarations appear
in only one place. If they need to be changed, they can be changed in one
place, and programs that include the header file will automatically use the
new version when next recompiled. The header file eliminates the labor of
finding and changing all the copies as well as the risk that a failure to
find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'.
It is most portable to use only letters, digits, dashes, and underscores in
header file names, and at most one dot.
Read more about using header files in official GCC documentation:
* Include Syntax
* Include Operation
* Once-Only Headers
* Computed Includes

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into executable file.
The source code of each library should be placed in a an own separate directory
("lib/your_library_name/[here are source files]").
For example, see a structure of the following two libraries `Foo` and `Bar`:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
and a contents of `src/main.c`:
```
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
```
PlatformIO Library Dependency Finder will find automatically dependent
libraries scanning project source files.

This directory is intended for PIO Unit Testing and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.

/* ULP Example: pulse counting
This example code is in the Public Domain (or CC0 licensed, at your option.)
Unless required by applicable law or agreed to in writing, this
software is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR
CONDITIONS OF ANY KIND, either express or implied.
This file contains assembly code which runs on the ULP.
ULP wakes up to run this code at a certain period, determined by the values
in SENS_ULP_CP_SLEEP_CYCx_REG registers. On each wake up, the program checks
the input on GPIO0. If the value is different from the previous one, the
program "debounces" the input: on the next debounce_max_count wake ups,
it expects to see the same value of input.
If this condition holds true, the program increments edge_count and starts
waiting for input signal polarity to change again.
When the edge counter reaches certain value (set by the main program),
this program running triggers a wake up from deep sleep.
