各位先進好:
最近看了AN235對於裡面有幾個地方不懂，然後將程式碼燒進APP001的板子上，用的是18F452。問題如下: (1) 程式碼中的Even flag在LIN程式中有什麼樣的功用呢? #pragma udata access TestSection2 near union { struct { unsigned EO1:1; // Even or odd flag unsigned EO2:1; unsigned EO3:1; }Bit; near unsigned char Byte; } MYCOUNT; (2) 程式碼中的l_bit_rate=71，我的版子用的是16Mhz的 震盪器，所以改成l_bit_rate=25，這樣對嗎? (3) 因為AN235沒附lin_d.h與lindefs.inc檔，所以我將AN235裡面的附錄C存成.H檔，附錄D存成.INC檔，附錄E存成.INC檔。而DEVICES.inc檔是用AN237的，這樣使用對嗎? (4)請問程式中的timer的中斷的作用是什麼呢? 謝謝~
