AVR-Chat

hi all 
well this is my first time to programing micro controller so i will use 
proteus program to be sure first that the program will be in  a right 
way to make simulation so i want your help if u don't mind plz  . i use 
proteus before but how can i use it with micro . i don't have till now 
a good idea . i want to make control on the speed of fan this fan will 
decrease the temperature in a small box but i have a question in my 
circuit i will use temperature sensor i think that its output will be 
sure voltage so i will put voltage source to the input of the micro or 
do we have the ability to use the sensor in the proteus   
thank u for reading my e_mail . i wait for ur replay  .BYE

Its not clear what you are asking. If your temperature sensor has a  
voltage output, then you probably want to use the analog-digital  
converter (ADC) of the micro. Then, you wold probably want to use PWM  
to control the fan motor, depending on the kind of motor it is.

I could describe how to do it, but it would be far better to point 
you in the direction of the help file first, which is found in ISIS's 
Help->Proteus VSM Help.  There is a whole section on working with 
microprocessors.  If you've used Proteus enough to simulate non-
programmable circuits, then the AVR simulation isn't a big step.
I would, however offer the following advice:
The more recent models (from the 'AVR2' library) simulate the reset 
pin as open=low, so for the Mega series, tie it high or your 
simulation won't run.
This is based on using AVR Studio and WinAVR - Save your Proteus work 
in the same directory as the .aps of you project and load the .elf 
file into the AVR.  That way you get source-level debugging.

If you have problems using it (and you have a legal copy of Proteus), 
I recommend going to Labcenter's user forums here:
