I had searched in the Discussion Forum for the whole moring but I couldn't find the right way to solve the problem I met,so I send this message hoping you guys can help me!Thanks in advance:-)My problem is as follows: 1.I want to define a macro,which is similar like function.It will be used in my communction interrupt service routine(so you can see that why I don't choose to call a function to realize it) 2.here's the definition of this macro: #define Macro_TestRxEnd(sbit Header_flag,uchar Header,uchar Tailer) \ { \ Return_flag = 0; \ if (!Header_flag) \ { \ if (Rxbuf == Header) \ { \ Header_flag = 1; \ ptRxBuf++; \ } \ else \ { ptRxBuf = xBuf; } \ else \ { \ if (Rxbuf == Tailer) \ { Return_flag = 1; } \ } 3.then the compile result is : Error C304: Bad Macro Parameter List so can anyone help me find out the right way to define such a long macro? I'm waiting for your good ideas earnestly!
"By your way,the ISR can only tell the main program that a total frame is received" Not true. The code I posted was just an idea of an outline; you need to fill in the details - including how to integrate it with the rest of your system For example, You could make the msg_type variable public...? No doubt you will also need to add other stuff shared between the ISR and the main code... Don't forget that 'volatile' keyword...!!
Today I've re-organized my uart-isr program on the base of the above good advice,and I get many useful ideas from this message,thank you all:-)
