[Moved] how to simulate Mt8870 with proteus7.2?

[Eip]

Hi! I wana simulate Mt8870 with proteus7.2 but as you know it does not have this
component !? please help me.What should I do!?

try this

Can you explain a bit about this file you have suggested? Coz i didnt find any 8870 Proteus model in it. A hex file was found and it would be great if you could let know how to use it.
Cheers

in fact it is a for substitute simulation 8870 using 8951 and keypad
I made it according to the datasheet 8870
P0.0 = Q0 p0.1=Q1 p0.2 = Q2 p0.3= Q3 p0.7=StD & p2.7 = TOE
how it works is:
* if button 1 is pressed then the data p.0.0-p0.3 = 0001
* if button 2 is pressed then the data p.0.0-p0.3 = 0010
* if button 3 is pressed then the data p.0.0-p0.3 = 0011
* if button 4 is pressed then the data p.0.0-p0.3 = 0100
so on until
* if the 0 key is pressed then the data p.0-p0.3 = 1010
any suppression issue StD pin high to low 1-->0
and if given the TOE pin low then p.0.0-p0.3 will high all

if there is an error please correct me this idea ..

Hey, plz.... u mail me details about DTMF decoder simulation in proteus at anilzkf@hotmail.com

Hey, plz.... u mail me details about DTMF decoder simulation in proteus at anilzkf@hotmail.com

as detailed as what you mean?
simulation that I created,just to help simulate DTMF receiver pin only,such as DTMF receiver using a microcontroller,and the microcontroller is of course that can be simulated,the pin 8870is used only STD (15), Q4 (14), Q3 (13), Q2 (12), Q1 (11) and TOE pin (10)
while the other pins are not used, to replace the phone line input, I use the keypad matrix as used on the telephone, the same right?

I'm not getting DTMF decoder ic at all. Tell me which library should i add???

I do not use the library, MT8870 was replaced by the AT89C51 as the receiver keypad and output as output MT8870

plz tell me that wheather ur hex file contain keypad code or not ????

of course .. It contains the program code read keypad

can you plz provide me the ASM code for that logic you have made?
