收到PIC18上與plib I2C函數有關的XC8錯誤「undefined symbols」錯誤

我一直試圖解決整個晚上的問題，而我似乎無法完成。我遇到了一個和這個非常相似的問題：Receiving "undefined symbols" error with XC8 concerning plib I2C functions 收到PIC18上與plib I2C函數有關的XC8錯誤「undefined symbols」錯誤

問題是，上一篇文章的推薦操作是更改爲PIC18以解決問題......我已經在使用PIC18！

我的設置如下：

MPLAB：產品版本：MPLAB X IDE V3.50 的Java：1.8.0_91; Java HotSpot（TM）64位服務器VM 25.91-b14 運行時：Java（TM）SE運行時環境1.8.0_91-b14 系統：在amd64上運行的Windows 7版本6.1; CP1252; en_CA（MPLAB）

XC8：1.40版

還安裝：外設庫換PIC18-v2.00rc3窗口-Installer.exe的

這裏是「有問題的代碼」 ...請注意，這不會在我的main.c文件中生成任何錯誤（沒有以紅色下劃線的函數）。起初，I2C功能以紅色標出，但是當我在代碼開始處添加#define I2C_V1時，它自行解決了......但是我仍然收到以下錯誤：

：0：error：（499）未定義的符號： _OpenI2C（DIST /默認/生產\ Lab2.X.production.obj）

下面的代碼：

void readTemp() 
{ 
    int TEMP = 0; 
    char temp2= 0; 

    // code pour le i2c 
    unsigned char temperature, addr, cmd_byte, status; 
    TRISBbits.RB0 =1; 
    TRISBbits.RB1 =1; 


    SSPADD = 0x31; // 100KHz Fosc = ?? Mhz 
    OpenI2C(MASTER,SLEW_OFF); 

    cmd_byte=1; //start with measure 
    StartI2C(); 
    // while (SSPCON2bits.SEN); // wait until start condition is over 
    // already included in StartI2C() 
    addr = 0x90; // adresse du TC74 modèle A0 en écriture 
    status = WriteI2C(addr); 
    while (SSPCON2bits.ACKSTAT); //Bit 6 (I2C_V4 routine does not ackn. 
    IdleI2C(); // while ((SSPCON & 0x1F) || (SSPSTATbits.R_W)) 
    WriteI2C(0x00); 
    while (SSPCON2bits.ACKSTAT); // wait for the acknowledge from slave 
    IdleI2C(); 
    RestartI2C(); // keep the line and avoid others to grab the line 
    while (SSPCON2bits.RSEN); // wait until re-start condition is over 
    IdleI2C(); 
    addr = 0x91; // adresse du TC74 modèle A0 en lecture 
    WriteI2C(addr); 
    while (SSPCON2bits.ACKSTAT); 
    IdleI2C(); 
    temperature = getcI2C(); 
    IdleI2C(); 
    RestartI2C(); 
    addr = 0x91; // adresse du TC74 modèle A0 en lecture 
    WriteI2C(addr); 
    while (SSPCON2bits.ACKSTAT); 
    IdleI2C(); 
    temperature = getcI2C(); 
    IdleI2C(); 
    StopI2C(); 
    CloseI2C(); 
    temp2 = temperature; 
    //return temperature; 


    TXREG = temp2; 
    LATDbits.LATD4 = 0; 

}

我已檢查鏈接器選項中的「外設庫中的鏈接」框。此外，如果它得到了整個日誌丟失的地方，有下列警告，我得到：

:: warning: (1370) peripheral library support is not available for the 18LF4550

我看着它，但無法找到任何信息，以什麼我可能會丟失/做錯了。

至於一些額外的上下文，我正在教授一門關於微處理器和PIC編程的課程，我正在從去年的其他人那裏學習一切。顯然，I2C模塊去年工作...我正在與我的同事覈對，看看自那時以來發生了什麼變化。也許是編譯器版本。

想想吧，我沒有重新啓動我的電腦後，我安裝了庫...不認爲這應該有所作爲，但我會嘗試反正。

謝謝您的幫助:)

您可能需要手動安裝傳統外設庫，因爲它不再作爲XC8的默認設置。 http://www.microchip.com/mplab/compilers，在下載選項卡中向下滾動到「Legacy Peripheral Libraries」。 – Unimportant

好了，永遠找下去之後，我的同事通知我，如果你設置該設備作爲PIC18LF4550庫不起作用。您必須在項目選項中將器件設置爲PIC18F4550，否則將無法與I2C外設庫（可能還有其他器件未經測試）配合使用。
