programming ip core 8051 spartan 3e

Hello,

I questioned on the forum but so far no response.
The Keil simulator does not fail, but do not get a good result in programs that have to act for themselves, for example:

mov p3,#01h mov r1,#00h
inici: mov p3, r1 inc r1 jmp inici
end

This program is so simple I hung with a 02h in the P3 and not with that increase.
In Canvio those in need of my interaction there is no problem.
for example:
inici: mov p3,p1 jmp inici
end

He believed that there could be a problem of the clock, but do not be.

Health and thanks

So what result, exactly, do you get??

Please pay attention to the instructions for posting source code: www.danlhenry.com/.../keil_code.png

"programs that have to act for themselves"

What, exactly, do you mean by that?
Surely, it is in the nature of any program that it should "act" for "itself"??

Where did you get your "Spartan 3e" board?
Can't your supplier provide assistance?

Are you experienced in FPGA design and/or microcontroller proramming?

This program is so simple that it is missing the "org 0"

Hello, I am a student final project is to implement a career 8051 ip core in 3e Spanta. L'experience I have with the FPGA is two subjects.
The problem I have is that once implemented the IP core is not operating with a loop without user interaction, example:

Org 0
Inici:   mov p3,#01h
                 Mov r0,#0ffh
        Mov  r1,#0ffh
Temp1:  Djnz  r1, temp1
Temp2:      djnz r0,temp2
                Mov p3,#02h
                Mov r2,#0ffh
                Mov r3,#0ffh
Temp3 : djnz r2, temp3
Temp4 : djnz r3, temp4
                Jmp inici
end

The P3 is the output of LEDs that have the plate, the response of the plate is a 1 in the leds i mas.No be nothing if not accept a DJNZ, JMP ...
But if I do a program

mov p3, p1
P1 is the input buttons, if I get a loop in which I can go play.

Health i thank you for the help

I think the above frenglish sentence translates to "P3 pins read '1'". p3.2 - p3.7 should be a '1', p3.0 - p3.1 should oscillate very fast (too fast for a LED which will just appear lit).

are you measuring with a scope or a meter or - are you relying on the LEDs?

not related to your problem, but your code is "overcomplicated"

Org 0
Inici:   mov  p3,#01h
Temp1:   djnz r0, temp1
Temp2:   djnz r0,temp2
         Mov  p3,#02h
Temp3 :  djnz r0, temp3
Temp4 :  djnz r0, temp4
         Jmp  inici
         end

will do the exact same

Erik

I tried the program and does the same, stays the P3.0 i will not turn on the P3.1 at any time.
Do not know if the problem is related to the djnz, the IP core that may need to configure depends instructions.

are you measuring with a scope or a meter or - are you relying on the LEDs?

I tried the program and does the same of, course, I said so

Erik

hello, I do not understand the question?

are you measuring with a scope oro en meter oro - are you relying on the LEDs?

you mean as I see it only P3.0 LED lights?
I say looking at it with the eye,

He mean: Try with an oscilloscope.

Your eyes cannot see the LED blinking, it's blinking too fast!

Hi, I understand that I comenteis eye can not see whether or not the lights P3.1, but I understand that this program the two would have to see leds on / off alike, no?
i even look at the oscilloscope.
Thanks for your time

... I think it would be advisable for you to get experience with a well documented debuggable case like a SILabs devboard before tackling the IP cores with their idiosynchracies.

now having the background to say "It MUST be so" makes it impossible for you to decicevely determine if it is a "core idiosynchracy" or your code.

As far as your actual problem it could be a spartan IP idiosynchracy such as
the pins in question having a dedicated purpose
a pin configuration register
the port bit routed differently
....

all beyond "normal behaviour" but quite typical for IP cores

erik: have you checked T1's maximum clock rate lately?

The troll took a long sleep.

Per, no reason you have to be so harsh on yourself.

Ciao.

erik: have you checked T1's maximum clock rate lately?
can't say, it depends on which derivative you refer to.
