使用 MPLAB X IDE C18 编译器编译我的 Microchip PIC18f4550 USB 项目时出现问题。编译器一直高亮 "syntax error" 并且不会编译
Trouble Compiling my Microchip PIC18f4550 USB project using MPLAB X IDE C18 compiler. The compiler keep highlighting "syntax error" and won't compile
我无法使用 MPLAB X IDE C18 编译器编译我的代码。下面的 link 是我 error.As 的打印屏幕图片的 link 你可以看到 IDE 说语句 LED3 = 0;[ 有语法错误=15=]
