Hello,

I asked a few questions some time ago, but I need to ask a few new questions about the way of programm one of NMIY micros.

Can you help me? I would be very grateful to you for your answers.

I have a <NMIY-0031 8051 CPU V1.0>. It has a chip where puts: <NMIY-0031 MONITOR 1996 New Micros>, and a big chip where is written: <SIEMENS 644-318-2 V 4.0 SAB8051A-16-N AUSTRIA BC INTEL'80>. This is the image: <http://www.newmicros.com/store/product_thumbnails/NMIY-0031.jpg>


These are the questions:



1st) The only way I get to send a string to serial port was the following:

**********************************************
.ORG H'8000

MOV DPTR,#(STRING1 - 1H)
LCALL 012AH

STRING1: .DB "HELLO WORLD\0"
***********************************************

But this always inserts a space character before my string. How can I avoid this space?. I have to say that I use <#(STRING1 - 1H)> instead <STRING1>, otherwise the first character of the string is eliminated (I don't
know why).




2nd) I need to manage 2 interruptions, so I decided to use the external INT0 and INT1 lines. I used a code similar to this:


************************************************************
.ORG H'0003 ;DEFINE INT0 HANDLER
LCALL INTER0
RETI

.ORG 8000 ;BEGIN OF CODE

MOV A,#H'85 ;SET IE TO ACCEPT INT0
ORL A,IE

BUCLE: AJMP BUCLE ;WAITING FOREVER, FOR THE INTERRUPTION

INTER0: PUSH PSW ;MANAGEMENT OF INT0
PUSH ACC
MOV DPTR,#(STRING0 - 1H)
LCALL 012AH
POP ACC
POP PSW
RET

STRING0: .DB "HELLO WORLD\0"
************************************************************

But nothing happens when I make a shorcircuit between INT0 (J5,PIN 17) and GND (J5,PIN 1) pins of J5 to simulate a interruption. What's the problem? Are these the wrongs INT0 pins? Anything wrong on the ASM code? Please help me!


3rd) I'm not sure about the micro I have. It's an Intel 8085? 8085A? 8031? The chip has written upside, <SIEMENS 644-318-2 V 4.0 SAB8051A-16-N AUSTRIA BC INTEL'80>, but I can't use all the instruction set of an 8085, because the <PseudoSam(tm) 51 assembler. V1.7.00> that New Micros provide me, gives the error: "Unknow opcode". But instead, the 8085 instrucction set works fine. Can you say me where can I find a full instruction set for my micro please?

4th) In the manual is written: <"See an 8031/51A data book for details on timer, counter, and interrupt programming.">. Can you recommend me a good one for my micro?


Thank you.

I look forward to hearing from you.

RAUL GLEZ.

I found this MOV DPTR,#(STRING1 - 1H) inserted a junk character at the beginning of the string. Where this,MOV DPTR,#STRING1 does not insert or eliminate any character as you experienced.

The INT0 interrupt vector is moved to 8003h as stated in the monitor.doc file
Here is the working interrupt INT0 sample program provided with the diskette,

; EX0, interrupt driven routine - running under monitor V1.1

.ORG H'8003 ; EX0 INTERRUPT VECTOR

MOV A,#H'55
MOV P1,A

RETI ; return from interrupt

.END

The microprocessor on the NMIY-0031 is SAB8051A manufactured by Siemens now is Infineon. Any 8051 opcode should be compatible.

Hello:

First of all I want to thank nmitech for his quick reply.

I would like to know where can I find the files he says:

"The INT0 interrupt vector is moved to 8003h as stated in the monitor.doc file
Here is the working interrupt INT0 sample program provided with the diskette"

I have this file: Nmiy0031.zip (1.005.121 bytes), which contains this files and directories (you provide me with this file a long time ago through mail):

8051mon.doc is included the interrupt vector table in ram

Thanks one more time nmitech!

Now I realize that I had been using an old version of the NMIY-0031 files, so 8051MON.DOC file only contains this:

***************** BOF ******************

NMI 8051 MONITOR V1.0

NMI 8051 MONITOR provides an easy way to access the program and
data memory and special function registers of 8051 processor.
The command line consists of one capital letter and optionally
one or two or three hex numbers.

The available commands and descriptions are following:

--------------------------------------------------------------
H :help
R <addr> :read internal data memory
D <addr> :read external data memory
P <addr> :read program memory
S <addr> :read special function register
A <addr> <size> :dump internal data memory
U <addr> <size> :dump external data memory
M <addr> <size> :dump program memory
W <value> <addr> :write onto internal data memory
O <value> <addr> :write onto external data memory
T <value> <addr> :write onto special function register
F <addr> <size> <value> :fill external data memory with value
X <addr> :execute
Z <addr> <size> :erase internal data memory
E <addr> <size> :erase external data memory
L :load INTEL HEX file
I <addr> <size> :dump memory in INTEL HEX format
--------------------------------------------------------------

<addr>, <size> = 4-digit hex number.
<value> = 2-digit hex number.

Example:

In order to read a special function register, PCON, whose
address is 87H,

Type:
>S 0087
Response:
xx xx = value of PCON







1







The external memory of 8051 board may be configured as 'program
only' or 'data only' or 'program/data' according to the jumper
settings of NMI CPU board (refer to the strapping diagram of 8051
board). Therefore, the commands 'D' and 'U' are valid only for
the memory location which is configured as either 'data only' or
'program/data'. While, the commands 'P' and 'M' work only for
'program only' or 'program/data' memory.

Since 8051 does not allow a write to the program area, there is
no command to write on the program memory. In order to write on
the program memory, the jumper should be reconfigured as 'data
only' or 'program/data'.

Command 'X' loads the data pointer with <addr> and executes from
that location. The memory location which contains the program to
execute should be configured as either 'program only' or
'program/data'. If <addr> is not program memory, or the byte at
<addr> is not a valid opcode, operation is not defined and system
may need RESET.

In order to load an INTEL HEX file, type 'L', and then send the
hex file to the board. Incoming hex data is automatically loaded
at the memory location specified in the file. Be sure that the
target memory is configured as either 'program/data' or 'data
only'.

Command 'I' dumps <size> of memory beginning at <addr> in INTEL
HEX format. The default number of bytes per line is 32 (20 hex).
You may utilize the capture function in your communication
software to capture the dump and create an intel hex file.

If you have any questions regarding NMI 8051 MONITOR, please call
214-339-2204.
******************* EOF *********************

And the file EX0INT.ASM doesn't even exist.

When I sent the list of the files that I had, I sent the list of a directory different from the one where I'm working because this it's full of temp files of mine.

But, when I was trying to locate the files that you said in my directory, I realized of the problem: I was using the older version.

I apologize for all this confusion and the troubles I caused to you. Sorry.

Thank you.
