it will be helpful if you provide more information like how you power the circuit and load plus how you hold your reset pin? It will be helpful if you attach schematic.
Re: a software for drawing electronic circuits
Whatever package you are using, just read its help file or user manual, look for the section where it explains how to draw/add user defined components.
I personally never used LCD with PIC microcontrollers but I am sure microchip or mikroElectronika must provide library routines for interfacing LCD. That will make your job lot simpler as you don't need to reinvent the wheel.
Re: pcb manufacturing files
Solder Paste layers and Component placement List are required when you opt for automatic placement of surface mount components.
Before soldering components to board, solder paste is applied to the board using special stencils. These stencils are made according to...
seems to me as you are working on arduino.... if analog pin is floating then it will pick interference, feed known voltage into this pin and verify values.
Please refer to following diagram:

Magnetic susceptibility system consists of: 1. MS3 meter and 2. Magnetic Susceptibility Loop.
Loop is connected to the meter through a coaxial cable "ONLY". So the same coaxial cable is used to excite...
You can downlaod Xilinx Webpack ISE which is free. All you need to do is to specify target harware and input your netlist. It will then implement your design and generate programming file. Depend upon your target hardware, you may need special cable to connect your target hardware to PC so that...
To design filters you must read some books or articles to build up understanding of it otherwise you will never understand what is going on. I personally find Analog and Digital Filter Design by Steve Winder a very good book.
Also, I would recommend you to start using simulators. There are many...
I am personally not aware of any such method because stepper motor in principle is an electromagnet which means if there is no current then motor will rotate freely. Can you give some information on motor, driver and weight?
Following are the links for detailed information on the whole system:

**broken link removed**
apart from that, what other information are you looking for?
Stepper motors requires holding current to stop in fixed position. If you remove that holding current or put excessive amount of weight then it will rotate. Disconnect it from controller and try to move it, you will get the answer.
Hi,
I am working on a magnetic susceptibility sensor to interface it to our existing electronics board.
The original system consists of a loop (through which we pass specimen) and a meter which powers the loop and receives pulses of certain frequency (depends upon specimen). This meter powers...
