# GPIO HAL Example
This example demonstrates and tests the functionality of the GPIO HAL. You can
use it to:
* Understand the logic of the GPIO HAL.
* Test your implementation of arch-specific GPIO HAL components if you are
developing a new port.
This example assumes a device with:
* 3 output pins (e.g. LEDs).
* 1 button.
# Supported devices
This example is expected to work off-the-shelf on the following boards:
* All CC13xx/CC26xx devices
* All CC2538 devices
# Extending for other platforms
Create a sub-directory with the same name as your platform. For example, for
platform `my-new-platform` create a subdirectory called `my-new-platform`.
Source files in this directory will be compiled automatically. In the most
simple case, all you will need is a source file called e.g. `pins.c` (it's OK
to use a different filename). In this file, you will need to provide
definitions of the variables used by the example to manipulate pins. These
variables are:
* `out_pin1`, `out_pin2` and `out_pin3` for output pins.
* `btn_pin` for the button pin.
Assign to those variables a value that corresponds to the output pin in your
board that you wish to test with the example. For example, if you have a LED
connected to pin 20, then you will need to
gpio_hal_pin_t out_pin1 = 20;

*
* All the functions below must be provided by the platform's developer. The
* HAL offers the developer a number of options of how to provide the required
* functionality.
*
* - The developer can provide a symbol. For example, the developer can create
* a .c file and implement a function called gpio_hal_arch_set_pin()
* - The developer can provide a function-like macro that has the same name as
* the function declared here. In this scenario, the declaration here will
* be removed by the pre-processor. For example, the developer can do
* something like:
*
* \code
* #define gpio_hal_arch_write_pin(p, v) platform_sdk_function(p, v)
* \endcode
*
* - The developer can provide a static inline implementation. For this to
* work, the developer can do something like:
*
* \code
* #define gpio_hal_arch_set_pin(p) set_pin(p)
* static inline void set_pin(gpio_hal_pin_t pin) { ... }
* \endcode
*
* In the latter two cases, the developer will likely provide implementations
* in a header file. In this scenario, one of the platform's configuration
* files must define GPIO_HAL_CONF_ARCH_HDR_PATH to the name of this header
* file. For example:
*
* \code
* #define GPIO_HAL_CONF_ARCH_HDR_PATH "dev/gpio-hal-arch.h"
