The ExpressPCBWindows layout software makes designing PC boards simple for the beginner and efficient for the professional. Its standard Windows user interface uses
all the familiar commands such as copy, cut, paste & dragging.

The program consists of three main modules
Layout Editor
Schematic Editor
Autorouter

which are embedded in a single user interface. Therefore there is no need for converting netlists between schematics and layouts.

FreePCB is a free, open-source printed circuit board layout editor for Microsoft Windows, released under the GNU General Public License. It is not quite finished, lacking some important features such as a Footprint Editor, Design Rule Check and Autorouter. However, it is quite capable of laying out a PCB and producing Gerber files. Some of its features are:
- 1 to 8 copper layers
- Board size up to 60 inches by 60 inches
- Footprint libraries courtesy of Ivex Design International Inc.
- Copper fill areas
- Imports PADS-PCB netlists
- Exports extended Gerber files (RS274X) and Excellon drill files
If you use FreePCB to design a PCB, I would STRONGLY suggest that you check your Gerber files with a program such as ViewMate (available for free here) before spending any money to have the boards manufactured.

The Merlin PCB designer package
Probably you are professionally involved with printed circuit manufacturing and you are looking for a cheap, easy to use package to design printed circuit boards (PCBs).
Or maybe you are just making a few PCBs for your job or at home, and even a non-commercial version of a standard PCB layout software would constitute a significant part of your monthly expenses.
In either case, you may have found that PCB design packages tend to be rather expensive and complicated pieces of software. But you already have a nice graphics program, like CorelDRAW, on your computer, and you wonder why you could not use it for designing PCB layouts. In fact, you can. Merlin PCB designer is a shareware solution that offers you the possibility to do just that.

Available on the net is a zip file containing CorelDRAW files (from version 7 on), and a large component library + manual.

Summary:
Integrated Development Environment (IDE) is an application that has multiple functions for software development. MPLAB�IDE an executable program that integrates a compiler, an assembler, a project manager, an editor, a debugger, simulator, and an assortment of other tools within one Windows�application. A user developing an application should be able to write code, compile, debug and test and application without leaving the MPLAB�IDE desktop. It is available for download FREE from our web site.
Bundled with MPLAB�IDE software are several code generation tools. MPASM�assembler is a full-featured universal macro assembler for all PICmicro�MCUs. It can produce absolute code directly in the form of HEX files for device programmers, or it can generate relocatable objects for MPLINK�linker. MPLINK�linker links relocatable objects from assembly or C source files along with pre-compiled libraries using directives from a linker script, and supports MPASM� MPLAB�C17, and MPLAB�C18. MPLIB�librarian ia a librarian for pre-compiled code to be used with MPLINK�linker. When a routine from a library is called from another souce file, only the modules that contain that routine will be linked in with the application. This allows large libraries to be used efficiently in many different applications. The latest versions of MPASM� MPLINK� and MPLIB�are bundled with MPLAB�and can be downloaded separately by choosing the web install and selecting only the MPASM� MPLINK� and/or MPLIB�

Description:
MPLAB�allows you to write, debug, and optimize the PICmicro�MCU applications for firmware product designs.
MPLAB�IDE software package includes the following: MPLAB�Project Manager, MPLAB�SIM Software Simulator, MPLAB�Editor, MPASM� Assembler Universal Macro Assembler for the PICmicros and other language products supporting the Common Object Description file format, MPLINK�Object Linker, MPLIB�Object Librarian

Avr fp calc and timer tool

To generate a delay loop in ASM source code just follow the steps in the left part of the window:
1. Enter the cycles the delay loop shall have. (in a future version you'll be able to enter the delay time in seconds).
2. Click the GO-Button
3. Save the generated code to a file or copy the source to your ClipBoard (Copy/Paste).
That's it.
Watch out for register collisions in your ASM source!
You may download, use and copy the programs for free! See german copyright info at top of page for details.

Flow Chart Programming for Microchip PIC Microcontrollers

Flowcode is a very high level language programming system for PICmicro�microcontrollers based on flowcharts. Flowcode allows you to design complex PIC based robotics and control systems by simply drawing a flow chart of your desired program in a matter of minutes even without any prior programming skills.


- Requires no programming experience
- Allows complex PICmicro programs to be designed quickly
- Uses international standard flow chart symbols (ISO5807)
- Full on-screen simulation allows debugging and speeds up the development process
- Facilitates learning via full suite of demonstration tutorials and virtual systems (burglar alarms etc.)
- Produces ASM code for a range of 18, 28 and 40 pin devices
- Allows C code or assembly code to be embedded as a macro
- Supports interrupts and A/D converters
How Flowcode Works
Flowcode is built on a C compiler - C2C. This is a general purpose 8/16 bit compiler designed specifically for PICmicro devices. Flowcode generates a C code file from the flow chart that you create. This C-code is automatically compiled into assembler code by the C2C compiler and then translated into a Hex machine code file using Microchip's MPASM assembler.
Any third party PIC programmer can then be used to download the resulting Hex file into the target PIC's program memory.
If Flowcode is used with an optional training and development board then this whole operation of compiling assembling and downloading is carried out with one button, providing a totally seamless PICmicro development tool.

Supported PIC Devices
Flowcode runs on Windows 98, 2000, NT, ME and XP and supports code generation for the following PIC devices:
PIC12C671, PIC12F629, PIC12F675, PIC16C61, PIC16C62, PIC16C62A, PIC16C62B, PIC16C63, PIC16C63A, PIC16C64, PIC16C64A, PIC16C65, PIC16C65A, PIC16C65b, PIC16C66, PIC16C67, PIC16C620, PIC16C620A, PIC16C621, PIC16C621A, PIC16C622, PIC16C622A, PIC16C71, PIC16C72, PIC16C72A, PIC16C73, PIC16C73A, PIC16C73B, PIC16C74, PIC16C74A, PIC16C74b, PIC16C76, PIC16C77, PIC16C710, PIC16C711, PIC16C712, PIC16C715, PIC16C716, PIC16C717, PIC16C745, PIC16C765, PIC16C773, PIC16C774, PIC16C84, PIC16CE623, PIC16CE624, PIC16CE625, PIC16F627, PIC16F627A, PIC16F628, PIC16F628A, PIC16F648A, PIC16F630, PIC16F676, PIC16F72, PIC16F73, PIC16F74, PIC16F76, PIC16F77, PIC16F737, PIC16F747, PIC16F767, PIC16F777, PIC16F84, PIC16F84A, PIC16F87, PIC16F88, PIC16F818, PIC16F819, PIC16F870, PIC16F871, PIC16F872, PIC16F873, PIC16F873A, PIC16F874, PIC16F874A, PIC16F876, PIC16F876A, PIC16F877, PIC16F877A
