pure-core:

How to use it:

The preferred way of including this library is to use CMake's FetchContents API.

Put the code below somewhere in your project's CMakeLists.txt

include(FetchContent)

FetchContent_Declare(
        pure-core
        GIT_REPOSITORY git@github.com:mudita/pure-core.git
)
FetchContent_MakeAvailable(pure-core)

After doing so, the new target pure-core will be available.

Alternatively, you can use GIT's submodules in conjunction with add_subdirectory

API

Available headers/modules are placed under hal directory.

hal
├── boot_control.h
└── boot_reason.h

To use them, simply add #include <hal/header_of_choice.h>

You will also need to link pure-core in order for the linker to find the correct symbols target_link_libraries(target PRIVATE/PUBLIC pure-core)

NOTE: In order to use boot_reason.h API you need to provide implementation of two functions:

extern uint32_t boot_reason_get_raw();
extern void boot_reason_set_raw(uint32_t raw);

For instance (use RT1051's SNVS general purpose registers):

uint32_t boot_reason_get_raw(){
  return SNVS->LPGPR[0];
}
void boot_reason_set_raw(uint32_t raw){
  SNVS->LPGPR[0] = raw;
}

Additionally, you need to link module that implements these functions to the pure-core using target_link_libraries(pure-core PRIVATE <target_that_implements_functions>)
