[参考译文] Code Composer Studio 工作区到头文件的链接

https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/986795/code-composer-studio-workspace-links-to-header-files

当 CCS 工作区中的程序文件丢失其指向引用的头文件的所有链接时、这些头文件具有所有别名声明。

是否有办法修复此问题、以便链接再次正常工作？ 例如、如果您在程序中右键单击任何别名寄存器值、例如"CS_clock_divider 2"、则不会发生任何情况。 通常情况下、CS_clock_divider@的声明会打开 cs.h 文件并突出显示"#define CS_clock_diver_2 CS_CTL1_divs_1"

我找到的唯一解决方法是打开一个新的工作区、并将相同的程序导入新的工作区。

 * MSP432 Clock System - HFXT Startup
 *
 * Description: This is a simple code example that starts the 48MHz crystal
 * attached to HFXTIN/HFXTOUT, sources MCLK from the crystal, and then
 * blinks an LED using SysTick (which is sourced from MCLK). This is meant
 * as a very elementary code example which shows the use how to start the
 * high frequency crystal and source clock signals from HFXT.
 *
 * This program runs infinitely until manually halted by the user.
