Simulate 8052 microcontroller with keiluVision3

wei wang

Hi,

I would like to debug a piece of source code based on 8052 microcontroller, the code is following:

MAIN:      MOV T2CON, #02h
           MOV tl2,   #0FBh
          MOV th2,   #0FFh
          MOV RLDL,  #0FBh
          MOV RLDH,  #0FFh
          MOV IE,    #0A0h
          SETB TR2
HERE:      LJMP HERE
           ORG  002BH
           CPL  P1.0
           RET
           END


The device I choose is "Analog device ->ADE7169F16".
As I know, it is based on 8052 microcontroller and it contains 3 timers/counters. But when I compile it, it appears error message as follow:

Build target 'Target 1'
assembling 8052.asm...
8052.asm(1): error A45: UNDEFINED SYMBOL (PASS-2)
8052.asm(2): error A45: UNDEFINED SYMBOL (PASS-2)
8052.asm(3): error A45: UNDEFINED SYMBOL (PASS-2)
8052.asm(4): error A45: UNDEFINED SYMBOL (PASS-2)
8052.asm(5): error A45: UNDEFINED SYMBOL (PASS-2)
8052.asm(7): error A45: UNDEFINED SYMBOL (PASS-2)
Target not created

Who can help me ? Thanks in advance!

    These are assmebler errors - they are nothing to do with simulation or debugging!

    You need to get your project to build cleanly (ie, without errors or warnings) before you can simulate or denug it.

    "8052.asm(7): error A45: UNDEFINED SYMBOL (PASS-2)"

    Does the message not tell you which symbol it considers to be undefined?
    Have you checked the rest of your code - have you provided a definition for the symbol in question?

    There is no ADE7169F16 listed here:
    http://www.keil.com/dd/chips/analogdevices/8051.htm
    Are you sure it's supported?

    Just because it's not on the list doesn't mean it can't be used; it just means that you have to do the work yourself - like providing the SFR definitions...
