深海游弋的鱼 – 默默的点滴

在开发Ti CC1310应用的时候遇到了SDK版本兼容问题。早期的应用都是从SDK 1.60版本的例子中修改得来的，最近在升级到SDK 2.x版本的时候遇到了编译不通过的问题。主要是某些变量名的定义改变了。

但是，翻遍了代码也没找打一个SDK版本宏。

于是只能通过ti/devices/cc13x0/driverlib/driverlib_release.h文件里面的DRIVERLIB_RELEASE_BUILD的版本号来进行区分，根据数字的不同来使用不同的代码，例子如下：

#include <ti/devices/cc13x0/driverlib/driverlib_release.h>

/*SDK 1_60_00_21*/
#if (DRIVERLIB_RELEASE_BUILD <= 50218)
const DisplaySharp_HWAttrs displaySharpHWattrs = {
    .spiIndex    = CC1310_LAUNCHXL_SPI0,
    .csPin       = CC1310_LAUNCHXL_LCD_CS,
    .extcominPin = CC1310_LAUNCHXL_LCD_EXTCOMIN,
    .powerPin    = CC1310_LAUNCHXL_LCD_POWER,
    .enablePin   = CC1310_LAUNCHXL_LCD_ENABLE,
    .pixelWidth  = BOARD_DISPLAY_SHARP_SIZE,
    .pixelHeight = BOARD_DISPLAY_SHARP_SIZE,
    .displayBuf  = sharpDisplayBuf,
};
#else /*SDK 2_10_02_10*/
const DisplaySharp_HWAttrsV1 displaySharpHWattrs = {
    .spiIndex    = CC1310_LAUNCHXL_SPI0,
    .csPin       = CC1310_LAUNCHXL_LCD_CS,
    .powerPin    = CC1310_LAUNCHXL_LCD_POWER,
    .enablePin   = CC1310_LAUNCHXL_LCD_ENABLE,
    .pixelWidth  = BOARD_DISPLAY_SHARP_SIZE,
    .pixelHeight = BOARD_DISPLAY_SHARP_SIZE,
    .displayBuf  = sharpDisplayBuf,
};
#endif

#include <ti/devices/cc13x0/driverlib/driverlib_release.h>

/*SDK 1_60_00_21*/

#if (DRIVERLIB_RELEASE_BUILD <= 50218)

const DisplaySharp_HWAttrs displaySharpHWattrs = {

.spiIndex = CC1310_LAUNCHXL_SPI0,

.csPin = CC1310_LAUNCHXL_LCD_CS,

.extcominPin = CC1310_LAUNCHXL_LCD_EXTCOMIN,

.powerPin = CC1310_LAUNCHXL_LCD_POWER,

.enablePin = CC1310_LAUNCHXL_LCD_ENABLE,

.pixelWidth = BOARD_DISPLAY_SHARP_SIZE,

.pixelHeight = BOARD_DISPLAY_SHARP_SIZE,

.displayBuf = sharpDisplayBuf,

};

#else /*SDK 2_10_02_10*/

const DisplaySharp_HWAttrsV1 displaySharpHWattrs = {

.spiIndex = CC1310_LAUNCHXL_SPI0,

.csPin = CC1310_LAUNCHXL_LCD_CS,

.powerPin = CC1310_LAUNCHXL_LCD_POWER,

.enablePin = CC1310_LAUNCHXL_LCD_ENABLE,

.pixelWidth = BOARD_DISPLAY_SHARP_SIZE,

.pixelHeight = BOARD_DISPLAY_SHARP_SIZE,

.displayBuf = sharpDisplayBuf,

};

#endif

其他的就是动态链接库的位置不同，导致链接的时候报告找不到链接库，需要重新设置一下，或者简单的移除一些找不到的库即可，例子中并没有用到全部的链接库。

我们在实际编写代码的时候，经常需要判断当前编译环境是否存在我们需要的头文件，如果不存在，则使用其他头文件代替。

以前这个操作都是通过外部的configure文件生成Makefile的时候指定。

最近的GCC已经增加了__has_include这个内置函数判断头文件是否存在。

这个功能最早是Clang实现的，现在GCC终于补上了这个功能。

例子如下：

#ifdef __has_include
#  if __has_include(<optional>)
#    include <optional>
#    define have_optional 1
#  elif __has_include(<experimental/optional>)
#    include <experimental/optional>
#    define have_optional 1
#    define experimental_optional
#  else
#    define have_optional 0
#  endif
#endif

#ifdef __has_include

# if __has_include(<optional>)

# include <optional>

# define have_optional 1

# elif __has_include(<experimental/optional>)

# include <experimental/optional>

# define have_optional 1

# define experimental_optional

# else

# define have_optional 0

# endif

#endif

Code Composer Studio 8.2.0.00007 ,GCC 5支持这个内置函数。
