Re: 請問18系列之RAM及*.LKR問題?

#721

資深會員

大家好:
那麼再請問=>
My_RAM0 UDATA該如何定址?
另外再請問=>程式如下(由help中copy的測試用):


;*******************************************************

;main.asm

;*******************************************************

  #include p16f877a.inc  ;Include standard header file

                         ;for the selected device.

  UDATA

  delay_value  res  1

  

  GLOBAL  delay_value    ;The variable 'delay_value',

                         ;declared GLOBAL in this

                         ;module, is included in an

                         ;EXTERN directive in the module

                         ;sub.asm.

  EXTERN  delay          ;The variable 'delay', declared

                         ;EXTERN in this module, is

                         ;declared GLOBAL in the module

                         ;sub.asm.

RST     CODE     0x0      ;The code section named RST

                          ;is placed at program memory

                          ;location 0x0. The next two

                          ;instructions are placed in

                          ;code section RST.

     pagesel  start       ;Jumps to the location labelled

     goto     start       ;'start'.

PGM     CODE              ;This is the begining of the

                          ;code section named PGM. It is

                          ;a relocatable code section

                          ;since no absolute address is

                          ;given along with directive CODE.

start

  movlw  D'10'

  movwf  delay_value

  xorlw  0x80

  call   delay

  

  goto   start

  end  

;*******************************************************

       ;*******************************************************

;sub.asm

;*******************************************************

  #include p16f877a.inc  ;Include standard header file

                         ;for the selected device.

  GLOBAL  delay          ;The variable 'delay' declared

                         ;GLOBAL in this module is

                         ;included in an EXTERN directive

                         ;in the module main.asm.

  EXTERN  delay_value    ;The variable 'delay_value' 

                         ;declared EXTERN in this module

                         ;is declared GLOBAL in the  

                         ;module main.asm.

PGM  CODE

delay

  decfsz  delay_value,1

  goto   delay

  return

  end

             為何會出現這樣警告?

      Warning[207] D:TESTMCUPICTS_GLOBALMAIN.ASM 7 : Found label after column 1. (delay_value)

請幫忙Thanks.

請問18系列之RAM及*.LKR問題?

#722

資深會員

大家好:
我是參考曾百由的著作"ASM與PIC18"(LCD部分),那麼
我自己加入一些副程式;有定義一些變數,利用equ或
cblock,但在watch或file register卻找不到?另外為何
一定要載入*.LKR檔呢?(18f4423).
以上兩個問題希望有那位高手幫忙解答.Thanks

Re: 請問那位高手知道CCS中RAM的變數如何定址?

#723

資深會員

大家好:
我應該已找到了.
unsigned char A;
#locate A=0x30要設稍為大一點,
可能是compiler要用到吧!Thanks.

請問那位高手知道HI-TIDEV3如何輸出List檔?

#724

資深會員

大家好:
我有從HI-TECH網站上,下載HI-TIDEV3來試.
覺得還不錯;只是它的open及close project
較奇怪,而且不知如何輸出List檔及詳細設定
還不是很清楚?希望大家多多教流.Thanks.

請問那位高手知道CCS中RAM的變數如何定址?

#725

資深會員

大家好:
我在CCS中定義
#define CNT 100
#byte A
而在程式執行時A卻會被重填回原值,無法--;
void main(void)
{
A=CNT;
for(;;)
{
if(A==8) break;
}
}
#int_tmr0
void timer0_isr(void)
{
if(A>0) A--;
RTCC=6;
}
但設為unsigned char A;時雖然正常但卻無法自行定址!!!
請高手幫忙解答,Thanks.

感謝你的回覆:
但像a=i*j及b=x/y卻沒有翻!
