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.
|
||||
|
||||

|
||||
* Include Operation
|
||||
* Once-Only Headers
|
||||

# Blink Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
This example demonstrates how to blink a LED using GPIO or using the [led_strip](https://components.espressif.com/component/espressif/led_strip) component for the addressable LED, i.e. [WS2812](http://www.world-semi.com/Certifications/WS2812B.html).
|
||||
|
||||
The `led_strip` is installed via [component manager](main/idf_component.yml).
|
||||
|
||||
## How to Use Example
|
||||
|
||||
Before project configuration and build, be sure to set the correct chip target using `idf.py set-target <chip_name>`.
|
||||
|
||||
### Hardware Required
|
||||
|
||||
* A development board with Espressif SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
|
||||
* A USB cable for Power supply and programming
|
||||
|
||||
Some development boards use an addressable LED instead of a regular one. These development boards include:
|
||||
|
||||
| Board | LED type | Pin |
|
||||
| -------------------- | -------------------- | -------------------- |
|
||||
| ESP32-C3-DevKitC-1 | Addressable | GPIO8 |
|
||||
| ESP32-C3-DevKitM-1 | Addressable | GPIO8 |
|
||||
| ESP32-S2-DevKitM-1 | Addressable | GPIO18 |
|
||||
| ESP32-S2-Saola-1 | Addressable | GPIO18 |
|
||||
| ESP32-S3-DevKitC-1 | Addressable | GPIO48 |
|
||||
|
||||
See [Development Boards](https://www.espressif.com/en/products/devkits) for more information about it.
|
||||
|
||||
### Configure the Project
|
||||
|
||||
Open the project configuration menu (`idf.py menuconfig`).
|
||||
|
||||
In the `Example Configuration` menu:
|
||||
|
||||
* Select the LED type in the `Blink LED type` option.
|
||||
* Use `GPIO` for regular LED blink.
|
||||
* Set the GPIO number used for the signal in the `Blink GPIO number` option.
|
||||
* Set the blinking period in the `Blink period in ms` option.
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
As you run the example, you will see the LED blinking, according to the previously defined period. For the addressable LED, you can also change the LED color by setting the `led_strip_set_pixel(led_strip, 0, 16, 16, 16);` (LED Strip, Pixel Number, Red, Green, Blue) with values from 0 to 255 in the [source file](main/blink_example_main.c).

||||
|
||||

||||

|
||||
I (7325) example: Turning the LED ON!
|
||||
I (8325) example: Turning the LED OFF!
|
||||
```
|
||||
|
||||
Note: The color order could be different according to the LED model.
|
||||
|
||||
The pixel number indicates the pixel position in the LED strip. For a single LED, use 0.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
* If the LED isn't blinking, check the GPIO or the LED type selection in the `Example Configuration` menu.
|
||||

||||

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.
