我正在尝试使用 globalVar.h 来清理和整理我的 main.c。但是我遇到了很多我和我的同事无法理解或解决的错误。

请有人这么好心，给我一个提示我可能做错了什么吗？

我正在为我的 PIC12F1572 使用 MPLAB X IDE 3.60 和 MPLAB XC8。

// main.c

#include "mcc_generated_files/mcc.h"
#include "globalVar.h"

void SDiagnose(sd_state_t SD_STATE);

void main(void)
{
    // Initialize the device
    SYSTEM_Initialize();

    INTERRUPT_GlobalInterruptEnable();
    INTERRUPT_PeripheralInterruptEnable();

    while (1)
    {
        if (gFlag_SDAktiv)          // Selbstdiagnose wird alle 180 Sekunden aktiviert
        {
            switch(gCnt_SD)
            {
            case 180:
                SD_STATE = START;
                SDiagnose(SD_STATE);                     //SD-PIN auf LOW ziehen, Laden starten
                break;

            case 190:
                SD_STATE = STARTMESSEN;
                SDiagnose(SD_STATE);               //Messung des Wertes während des Ladens und der Rekuperation starten
                break;

            default:
                break;

            }
        }   
    }
}

void SDiagnose(sd_state_t SD_STATE)
{ 
    switch(SD_STATE) 
    {
        case START:
            PIN_SDIAGNOSE_SetDigitalOutput();
            PIN_SDIAGNOSE_SetLow();
            break;

        case STARTMESSEN: 
            ADC1_StartConversion();
            break;

        default:  
            break;      
    }
}

    // add your TMR1 interrupt custom code
    // or set custom function using TMR1_SetInterruptHandler()

    gCnt_SD++;

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 .c 模块之一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;
