问 最好能举个例子，或提供个例子资料什么的 答 1: 谁有这方面的例子 答 2: like this onevoid AssemProgram()
{
asm("string of assemble \n"
"another string of assemble \n"
...
);
}
ok you CANuse this function now. 答 3: 我需要调用整个程序的，因为汇编程序很长 答 4: 你在汇编之前用asm，然后把汇编程序用括号括起来！ 答 5: 汇编代码很长我不会要一句一句括吧 答 6: 看过来将你的汇编文件改名字为*.S，然后和C的主程序一起加入工程，在C中要调用的汇编函数在C中声明成外部函数，在汇编文件函数名前面加上下划线，后面是两个冒号，其他的不用改，编译就好了 答 7: 可是在汇编中不能写portd等的寄存器，只能用单片地址来表示吗也不能用equ等伪指令
有没有办法，能使这个汇编能像纯汇编那样运用自如 答 8: 可以的我的做法是将汇编文件包含的头文件中的.equ去掉，只留下UDR1 = $9C，这样的语句，就可以编译通过了，这样c调用的汇编文件就和纯汇编一模一样了（指的是语法，格式当然稍有不同） 答 9: iccAVR库中有aiom128.s这是汇编头文件 iccAVR库中有aiom128.s等等。这是汇编头文件 答 10: 这样的话就会出现新的问题：因为必须去掉相应的.def指令，那么
XL =r26
XH =r27
YL =r28
YH =r29
ZL =r30
ZH =r31
就会出现r26..r31等等出错，因此在汇编中无法使用x、y、z
这该怎么办 答 11: .def指令不要去掉下面是我改的128的头文件，你要是用128的话，可以直接考过去用，不是的话就仿照改吧
m128def.inc

;*
;* Number : AVR000
;* File Name : "m128def.inc"
;* Title : Register/Bit Definitions for the ATmega128
;* Date : 07.09.2001
;* Version : 1.0
;* Support telephone : +47 72 88 43 88 (ATMEL Norway)
;* Support fax : +47 72 88 43 99 (ATMEL Norway)
;* Support E-mail : AVR@atmel.no
;* Target MCU : ATmega128
;*
;* DESCRIPTION
;* When including this file in the assembly program file, all I/O register
;* names and I/O register bit names appearing in the data book CANbe used.
;* In addition, the six registers forming the three data pointers X, Y and
;* Z have been assigned names XL - ZH. Highest RAM address for Internal
;* SRAM is also defined
;*
;* The Register names are represented by their hexadecimal address.
;*
;* The Register Bit names are represented by their bit number (0-7).
;*
;* Please observe the difference in using the bit names with instructions
;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc"
;* (skip if bit in register set/cleared). The following example illustrates
;* this:
;*
;* in r16,PORTB ;read PORTB latch
;* sbr r16,(1<;* out PORTB,r16 ;output to PORTB
;*
;* in r16,TIFR ;read the Timer Interrupt Flag Register
;* sbrc r16,TOV0 ;test the overflow flag (use bit#)
;* rjmp TOV0_is_set ;jump if set
;* ... ;otherwise do something else

答 12: 是在 iccAVR中编吗？aiom128.s不是汇编的头文件吗？
怎么不用这个呢？
问一下
是不是这样调用
;;;void testasm(void);
_testasm::
.....///
这是（*.s）
void main(viod)
{
;;;;
testasm();
;;;;;;;
}
两个文件在一个工程里。。
这样调用可以吗？
我模拟一下，怎么没有反应呢？？？ 答 13: 这样：extern void testasm(void);//in C

void main(void)
{
testasm();
}

//以下在in testasm.s

_testasm::
....
ret

了解一下
