how to design a circuit with AT90S2313 microcontroller?

start with the datasheet\nhttp://www.atmel.com/dyn/resources/prod_documents/DOC0839.PDF\nthen look in the I/O ection to design the interface crcuits\n\nthen you have to get a programmer and compiler that will work for that chip. Often they have evaluation circuits that will help you get started. Check the mfg website for something of that nature.

Yupp... but unfortunately is a hardcopy on my desk. Perhaps you may straight to tell us what\n\n1. You are designing from HT to Transformer 11kV / 415V\n2. You are designinig from Transformer to LV ??\n3. What is the kVA of the transfomer?

You can find printable schematics on the page I've linked below.\n\nGood luck.

yeah you can use a switch (voltage switch) or if you can use binary logic, need to know how much voltage/current you are dealing with

Here are some sites that may help.  Both have circuit examples utilizing LVDT's.  Hope this helps.

Use a 7106 or 7107 IC.  They provide analog to digital conversion and drivers for a liquid crystal display.  The source in "references" provides kits to make a panel mounted ohm or volt meter using these ICs.  \n\n"Google" these ICs and you will find more.

It's a bit too complicated to explain in a quick answer. There would probably need to be some kind of back and forth dialogue for me to understand exactly what you need to do. But here's a link to the manual, it's well-written and should give you anything you need:\n\nhttp://www.akaipro.com/supportdocuments.html#MPC1000

Your question is very vague.\n\nGive more description as what you want. or contacta  hardware engineer.

If you go to PCB Express on-line, you can download some simple graphical type programs to design a schematic and do a board layout for a prototype board.  You enter credit card information and in a few days, you will have three prototype boards mailed to you.  You then populate them and solder it up.  This is only one of several services to do this.  It works pretty well, assuming that you are willing to do the work yourself.  \n\nIf not, I would make a flowchart on paper of what you want the circuit to do and submit it to an electronics or robotics on-line site or message board for help, go talk to a teacher or professor, etc.

You would have to use some-kind of a network interface chip or u can use a off the shelf PCI/ISA network card. One of the popular chips is the Realtek RTL8019, i used this to interface a mp3 player to the network. I have heard of the following being used with Atmels AVR RISC micro-controllers which are very popular among hobbyist's.\n\nhttp://www.ethernut.de/en/index.html\nhttp://www.avrfreaks.org/index.php?module=FreaksTools&func=viewItem&item_type=tool&item_id=289\n\nJust search on the internet and u would come up with thousands of projects doing the same.

Since it is only 16 options, you can just use a logic circuit. If it were more it would be best to convert each bit to analog with a summing op-amp circuit and have each bit input resistor double the last value. Then the two values could be fed into a comparator. A special logic circuit would need to be added for the equal [same as below] which would then logically override the comparator output for a 1 or 0 meaning L or G. \n[it would do this by making the outputs: \nG = comparator_output and not E  \nL = not comparator_output and not e]\n\nTo make the logic circuit you will need a bunch of logic gates. You can do everything with a slew of two input nor gates, or you can get some ands, ors, xors, and inverters of as many as 4 inputs each. That is up to you. \n\nTo figure out how to hook them up you need to draw a grid that is 4x4, down the side label it with the first number AB possible values:00,01,10,11 across the top label it with the second number CD possible values:00,01,10,11.\n\nNow in the grid fill in what output you want, presumably you will have three outputs, E,L, and G. E would be diagnal from top left to bottom right. The six above and right are Gs, and the six below and left are Ls.\n\nLike this except straight and with lines:\nAB  CD:00,01,10,11\n00      E  G  G  G\n01      L  E  G  G\n10      L  L  E  G\n11      L  L  L  E\n\nnow take each area that you can can and work it into the logic equation. For example the Es are two xor gates ANDed together. \nE = ((a xor c) and (b xor d)) [this is kind of by definition of equals there was no real trick here]\n\nthen you can see the top-right four Gs can easily be singled out with:\nG(1)=(c and (not a))  [that is c is 1 and a is 0]\n\nnow you can do the same for the Ls on the bottom left:\nL(1)=(a and (not c))\n\nNow you can pick up the straglers one at a time or as a group. for example the AB/CD=11/10 is an L, and so is the entire bottom row where ab=11 except for the E which is already known. so you could do this:\n\nL(2)=(a and b and c and (not d)) [to pick it up alone]\nor \nL(2)=(a and b and (not e)) [which gets some other Ls you already got which is fine since you are going to and all the Ls together later to get the final L]\n\nnow you need L(3) and then pick up G(2) and G(3) the same way. After that the final step is to or them all together:\n\nL= L(1) or L(2) or L(3) [same for Gs]\n\nNow you can take the rules for modifying and simplifying the gates down to only 2-input nors if you want, or you can keep all the various gates and hook them all up. \n\nIf you really want to get fancy then you can send the output to an alphanumeric LED and actually print the letter, but that is a whole nother task. \n\nEach segment would then be either always on, always off, or some logical combination of the three outputs G and E [since the L segments would always be on]
