How can i create a new device in the database?

Hello,
I work at CTI Design House -Brazil (http://www.cti.org.br) and we develop a microcontroller based on the 8051. However, our microcontroller uses registers that are not available in 80C51 listed in the database. I'm having problems when I try to build the target, this case the following message appears "VER_I2CSM_TX_1B_NEW.asm (130): error A1: ILLEGAL CHARACTER IN NUMERIC CONSTANT"
Here is the line indicated by the message.

mov  0E8, # 001h; </ pre>.

Can someone show me the solution to this problem?

Sincerely,
Claudionor Santos

 RE: How can i create a new device in the database?

what about this:

MOV 0E8H,#1
MOV 0xE8,#1

 RE: How can i create a new device in the database?

Thanks,
it is working now !

But have some warning messages, like that:

 *** WARNING L5: CODE SPACE MEMORY OVERLAP
    FROM:    0000H
    TO:      0002H
*** WARNING L1: UNRESOLVED EXTERNAL SYMBOL
    SYMBOL:  ?C_START
    MODULE:  STARTUP.obj (?C_STARTUP)
*** WARNING L2: REFERENCE MADE TO UNRESOLVED EXTERNAL
    SYMBOL:  ?C_START
    MODULE:  STARTUP.obj (?C_STARTUP)
    ADDRESS: 080AH

 this is ridiculous

we develop a microcontroller based on the 8051.

anyhow what ARE you doing?
mov 0E8, # 001h; is assembler and the error messages are from 'C'
is seems like/could be that you include startup.a51 in an assembler program

Erik

it is a assembly code.

 the errors you get are, as I stated, typical for

startup.a51 included in the linking string

check the .map

thanks ,

i just could not understand when you wrote "this is ridiculous."

could you be clear ?

 RE: How can i create a new device in the database?

To answer the original question. You can modify some things in a device data base. First go to File -> Device DataBase... and open the dialog. Carefully select a device as near to your device as possible(carefully read the device descriptions). To make a copy of the existing device data base, change the name, device family and device type to your device names, etc. Modify the any data necessary and click the Update AND the the ADD button. At this point you can define the register .h files that you have created to define your register set. This is just your Regxxx.h file that you have created. You can change other device descriptions as necessary.

Now the real hard part. If you have peripherals not common to the device that you select to change, you must write your own peripheral types using the AGSI and/or the AGDI features in this toolset. These new tools will be written in C++ external to the Keil Tools and you will create a new .dll for your simulator. Templates are availble on this website.

All of this is described in detail in the PK51 User's Manuals at this website. You must read and study these manuals carefully to implement any serious changes to the Device Database.

Good Luck. You will need it.
