I m using proteus 7.4 professional.i want to design the circuit of GSM based robot.when i tried to to draw it in proteus i did'nt find the MT8870 IC(DTMF).plz help me8O
Firstly you'll have to upgrade to the latest version of proteus, to have a clear idea whether labcenter have included the device in proteus or not..
If it is not available there, then you 'll have to create the device yourself for that I would suggest to go through proteus help files.
BTW:
I am pretty impressed with the schematics you have drawn and I am more interested in knowing the application that you have used to draw attached schematics..
sir abidr, i hope you can help me with my proteus, 7.7
whenever i clicked on my worksheet my design, or my component were all lost, do you have any idea with this problem?
Probably from the tools menu you had had selected delete all option, that is why your components are all deleted.
Once you open your design file, take the mouse pointer to the left side of the screen where there are icons, click on the arrow icon on the top and hopefully your design file should be alright now.
