我正在尝试使用globalVar.h来使我的main.c更清洁和整理。 但是，我和我的同事无法理解或解决许多错误。
请一些人如此友好并给我一个提示我可能做错了什么？
我在PIC12F1572上使用MPLAB X IDE 3.60和MPLAB XC8。

我希望，你能帮助我！ 提前谢谢！
答案 0 :(得分：0)
您在global.h中声明了4个外部变量
EXTERN volatile sd_state_t SD_STATE;
EXTERN volatile unsigned char gFlag_AdcReady;
EXTERN volatile unsigned char gFlag_SDAktiv; // = 0; The assign should go in .c
EXTERN volatile unsigned char gCnt_SD; // = 0;
您需要在其中一个.c模块中为这些变量分配空间。这也是初始值分配的地方。它们将在启动时自动设置为零。
volatile sd_state_t SD_STATE;
volatile unsigned char gFlag_AdcReady;
volatile unsigned char gFlag_SDAktiv;
volatile unsigned char gCnt_SD;
