STM32F4 Hardware Abstraction Library

It's a copy of STM32F4 HAL wrapped to static library using cmake

Additionally it provides:

• Toolchain file cmake/arm-none-eabi.cmake
• OpenOCD caller for deploy and debug

CMake Toolchain File

CMake Toolchain file provides set of compiler and linker flags for "arm-non-eabi-gcc" compiler

To use the toolchain file one should either call cmake with -DCMAKE_TOOLCHAIN_FILE=<path>/cmake/arm-none-eabi.cmake or specify CMAKE_TOOLCHAIN_FILE variable in CMakeLists.txt file before project() command:

cmake_minimum_required(VERSION 2.8)
set(CMAKE_TOOLCHAIN_FILE ../STM32F4xx_DSP_StdPeriph_Lib/cmake/arm-none-eabi.cmake)
project(test1)

OpenOCD caller

There is a FindOpenOCD.cmake module that searches for openocd binary and provides option to add deploy and debug target.

The path to FindOpenOCD.cmake module is automatically added by toolchain file.

OpenOCD deployment

Note:

For now the OpenOCD flags are set to st_nucleo_f4 board.

There are two option to deploy target to board:

Post-build command

enable_deploy() command adds deployment command as Post-build command.

Sample usage:

find_package(OpenOCD REQUIRED)
add_executable(test1 main.c)
enable_deploy(test1)

In this case building executable will call openocd to deploy binary to board.

Deploy target

add_deploy_target() command adds deployment target deploy_${TARGET} that depends on ${TARGET}.

Sample usage:

find_package(OpenOCD REQUIRED)
add_executable(test1 main.c)
add_deploy_target(test1)

Calling:

$ make deploy_test1

OpenOCD debuging

add_debug_target() command adds debuging target debug_${TARGET} that depends either on deploy_${TARGET} or on ${TARGET}

If deployment is neither enabled (post-build) neither added, it automatically adds deploy_${TARGET}.

Sample usage:

find_package(OpenOCD REQUIRED)
add_executable(test1 main.c)
add_debug_target(test1)

Calling:

$ make debug_test1
