ARM STM32 的 Ceedling CMock 设置

Ceedling CMock settings for ARM STM32

我一直在为 STM32 设置 Ceedling。 howto 非常稀少,到目前为止,我几乎没有 google。幸运的是,该框架相对于它的大小而言是相对透明的。 是PIC配置。我设置了类似的东西 (project.yml):

...
:defines:
  # in order to add common defines:
  #  1) remove the trailing [] from the :common: section
  #  2) add entries to the :common: section (e.g. :test: has TEST defined)
  :commmon: &common_defines #[]
    - STM32F103xB
    - UNITY_INT_WIDTH=32
    - CMOCK_MEM_INDEX_TYPE=uint32_t
    - UNITY_LINE_TYPE=uint16_t
  :test:
    - *common_defines
    - TEST
  :test_preprocess:
    - *common_defines
    - TEST

到目前为止一切顺利(尚未尝试实际工作)。添加了这个定义

    - CMOCK_MEM_PTR_AS_INT=uint32_t

我有一个警告:

/vendor/ceedling/vendor/cmock/src/cmock.c:105:40: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
   index = *(CMOCK_MEM_INDEX_TYPE*)((CMOCK_MEM_PTR_AS_INT)next - CMOCK_MEM_INDEX_SIZE);

难怪,因为next是PC平台的64位指针。我仍然不确定是否必须控制 CMOCK_MEM_PTR_AS_INT 。这取决于 CMOCK_MEM_PTR_AS_INT 是否为关键目标 (ARM) 平台定义。

到目前为止我还没有找到STM32的例子。

这是来之不易的序列,完成了 Eclipse 集成:

安装 Ceedling:

$ gem install ceedling

创建 Ceedling 项目(故障排除 #215):

myproject $ cd ..
$ ceedling new myproject
$ cd myproject/vendor/
$ rm -rf ceedling/
$ git clone --recursive https://github.com/throwtheswitch/ceedling.git

修改vendor/ceedling/plugins/module_generator/config/module_generator.yml

:module_generator:
  :project_root: ./
  :source_root:  Src/
  :inc_root:     Inc/
  :test_root:    test/

修改project.yml:

...
:paths:
  :test:
    - +:test/**
    - -:test/support
  :source:
    - Src/**
  :include:
    - Drivers/**
    - Inc/**
  :support:
    - test/support
...
:defines:
  :commmon: &common_defines  # A nice typo, next to invisible :)
    - STM32F103xB
...
:cmock:
  :strippables:
    - volatile
...
:plugins:
  :load_paths:
    - vendor/ceedling/plugins
  :enabled:
#    - stdout_pretty_tests_report
    - stdout_gtestlike_tests_report
    - module_generator

Eclipse C/C++单元插件配置:

  • Main/Project: 我的项目

  • Main/Application: /home/user/.gem/ruby/2.5.0/bin/ceedling

  • Main/Disable 自动构建

  • Arguments/Program 参数:clobber\ntest:all

  • Testing/Test 跑步者:Google 测试跑步者

  • 环境:变量 TERM 值 xterm
