[英]Trouble Compiling my Microchip PIC18f4550 USB project using MPLAB X IDE C18 compiler. The compiler keep highlighting "syntax error" and won't compile
[英]Error on compiling c file on MPLAB X ide
在Windows上嘗試使用MPLAB X進行編譯時,出現以下錯誤。
newmain.c:40:9: error: unknown configuration setting: 'JTAGEN'
newmain.c:61:2: error: 'LATA' undeclared (first use in this function)
newmain.c:62:2: error: 'TRISA' undeclared (first use in this function)
newmain.c:61:2: error: 'LATA' undeclared (first use in this function)
我在2台不同的計算機上(在Windows 8.1和Vista上)嘗試了此操作,但是它們都給了我相同的錯誤。
好像xc.h文件已經包含在項目中,因為我可以打開該文件。 我也用谷歌搜索這個問題,但是沒有解決方案。
如果您能給我解決該問題的方法,我非常感謝。
我還附上描述該項目項目屬性的照片。

您收到的錯誤表明編譯器沒有看到任何庫引用這些寄存器。 而是將它們視為常規變量。
您應該包括正在使用的處理器的特定頭文件,並檢查其中包含哪些寄存器以使您的問題更有意義。
