/**
|
|
* Umbrella header for AP_HAL_Empty module.
|
|
* The module header exports singleton instances which must conform the
|
|
* AP_HAL::HAL interface. It may only expose implementation details (class
|
|
* names, headers) via the Empty namespace.
|
|
* The class implementing AP_HAL::HAL should be called HAL_Empty and exist
|
|
* in the global namespace. There should be a single const instance of the
|
|
* HAL_Empty class called AP_HAL_Empty, instantiated in the HAL_Empty_Class.cpp
|
|
* and exported as `extern const HAL_Empty AP_HAL_Empty;` in HAL_Empty_Class.h
|
|
*
|
|
* All declaration and compilation should be guarded by CONFIG_HAL_BOARD macros.
|
|
* In this case, we're using CONFIG_HAL_BOARD == HAL_BOARD_EMPTY.
|
|
* When creating a new HAL, declare a new HAL_BOARD_ in AP_HAL/AP_HAL_Boards.h
|
|
*
|
|
* The module should also export an appropriate AP_HAL_MAIN() macro iff the
|
|
* appropriate CONFIG_HAL_BOARD value is set.
|
|
* The AP_HAL_MAIN macro expands to a main function (either an `int main (void)`
|
|
* or `int main (int argc, const char * argv[]), depending on platform) of an
|
|
* ArduPilot application, whose entry points are the c++ functions
|
|
* `void setup()` and `void loop()`, ala Arduino.
