I am a beginner and I need a graphical simulator to write assembly programs based on 68000 microprocessor. I have found Easy68K simulator. It works and the features are good, but is there any newer/better graphical simulator than Easy68K? I need the most uptodate one.
Latest version of EASy68K emulator is v5.12.29 at the moment. You can find this information (and follow the updates) at EASy68K forums. You can download latest version from the URL below;
http://www.easy68k.com/
If you want some graphical simulation, you may like to use an emulator of a computer using 68K CPU like Commodore Amiga or Atari ST. I prefer UAE Amiga emulator. Of course you need to learn about Amiga hardware and stuff but you may also like the experience, test your 68k routines, see or hear the output.
My advice may not be suitable for your needs. But you already know about EASy68K and i know no better way than Amiga/Atari ST emulators myself.
You may want to check out BSVC.
But this depends on what you mean by "graphical" simulator...BSVC has a graphical user interface, but doesn't simulate graphics. Hope that helps!

Do Chromebooks offer adequate programming capabilities offline?
I can never guarantee my WiFi access.
I know I can access local files, and being Linux-based, what does this mean for programming offline?
Also, I am returning to obtain my MSc in IT. Would this be a good purchase for such a cause? I am focusing on web development (HTML, JavaScript, Rails).
I want to know specifically if a Chromebook (I have my eyes on the Acer C720) can get the work done. True, I'll probably rare ever be offline, but I want to know if I'll be able to both edit code, then run it to troubleshoot.
My main points: editing and running code on a Chromebook. Also, could I amend the drawback by running Windows or Linux (ie, Ubuntu, Mint)?Thanks guys for any advice.
I use an Acer C720 Chromebook (2GB RAM, 16GB SSD) as my Meteor (Javascript, HTML. CSS, MongoDB) development machine. The specs may sound poor but in reality - thanks to the fantastic Haswell chip - the laptop is great.
I have Xubuntu installed instead of ChromeOS... so maybe that is not a real answer to your question.
It's a fantastic little machine - long battery life and boots in a few seconds. I tried Bodhi Linux first but find Xubuntu better for my needs.
I expanded the storage using a keep-in tiny UltraFit 64GB USB 3.0 flash key. Amazing device.
I use an HDMI monitor when doing longer coding sessions.
Device cost me $150 on eBay and around $25 for the USB key.
I use the free http://komodoide.com/komodo-edit/ as my editor.
If you feel like taking the plunge and converting from ChromeOS to Xubuntu, these two links may help:
BIOS changes: https://blogs.fsfe.org/the_unconventional/2014/09/19/c720-coreboot/

Good luck and enjoy!
I have to develop an sdk for biometric applications, but don't know how to start development. Either I need to write my own algorithm or use written by other and are free. If I use others algorithm then it is difficult to say about the quality and results.
Is there any standard source available that can help me in term of quality.
I don't wanna use any available sdk
Anybody who can help me in this regard will be a plus for me.
Thanks
Khizar
Programming for biometric devices depends largely on the device you use. Chances are you've received software with your device that has its own evaluation algorithim which then outputs a value, usually a hash, that your program can then handle.
If you're looking for a generic option, Google has several. One option being m2sys.
Does anybody know of an existing Flex component that does VT500 terminal emulation?
We are gradually replacing terminal-based user interfaces with an AIR-based GUI.
We would like to have a terminal emulator embedded in that new AIR GUI, in order to give our users an integrated user experience when navigating between our old and new software.
Emulation of other VT-series terminals than the VT500 could also be usefull.
Btw, I'm not interested in writing it myself (nor having it written for me) because it would only be a nice-to-have in our software architecture.
Thanks,
Pieter
Isn't the whole point of using Air and upgrading the technology is that you DON'T need to use a terminal anymore? Seems a bit redundant.
I don't think you'll find anyone that has already created the emulator, but it can't be that hard to implement if you really need the functionality. I know I've seen an AJAX implementation of it (anyterm.org) that uses the ROTE library for the virtual emulator. You might want to look into that.

I've a Good Command over C++, But I've never done anything anything on device programming. I've some basic understanding on Digital Logic Design. But I am complete Noob in Electronics. Currently I am getting huge interest on microcontroller Programming.
Where To Start ?
I don't think one really needs to have huge amount of knowledge on electronics to run a program on a microcontroller.
I am using Linux. and I've downloaded Keil. never tried to run it through Wine. I've ran it in Windows. But how the code works is not completely clear to me. though I can understand Logic as its written in C. But Its still like a Fog to me.I Just need a Quick Kickstart.
SO is not the best site to ask this kind of question. There's really a large distinction between programming for a PC and programming for an embedded system, other SE sites specialize in physical computing. I got this email from Robert Cartaino on Tuesday:
...Barring any last-minute interest from
[chiphacker.com], we will be launching [electronics.stackexchange.com]
either tomorrow [Wednesday 9/22] or
Thursday.
So, go commit to electronics.stackexchange.com here, and browse chiphacker.com while you wait. Take a look at these questions on Chiphacker:
How to become an embedded software developer?
Steps to learning Arduino Programming
PIC Programming
What are the best beginner project[s] using an arduino
There are a few things you should consider when planning your entry path to embedded systems programming.
What do you want to do?
What do you know how to do?
How fast are you comfortable learning?
I've outlined a few options in the following paragraphs.
You tagged your question linux-device-driver, does this mean that you want to make a custom device to use in Linux? If you meant embedded-linux, then you're into a larger class of microcontrollers. I suggest that you look at the BeagleBoard, also look at this Chiphacker question for some other options. If you want to do embedded linux, and want to build your own board, you'll first need to build up some experience in simpler levels of embedded systems design.
You also tagged your question avr, which is a popular microcontroller class made by Atmel (check out the avrfreaks forum for more info). I started learning embedded systems on the ATmega324p; they really have great documentation, are easy to use, and there are more sites online for the avr than most any other processor.
If you want an easier learning curve, I suggest taking a look at the Arduino environment. It uses Wiring, which is very similar to C/C++, and the Arduino can be enhanced with 'shields', which are modules that can be plugged into the Arduino main board to add functionality. This is your Quick Kickstart.
A good learning path would be to get familiar with the Arduino, then build your own AVR board (possibly a Linux device, like a joystick), then work with an ARM-based development kit, and finally move on to to building your own embedded linux board. You can skip a few steps if you don't mind a steep learning curve, or stop at any point along the way if a given level's capabilities satisfy your needs. You don't necessarily need a "huge amount of knowledge on electronics to run a program on a microcontroller", it's true, but you should understand some basic things like voltage and current before you try to light an LED or connect two devices.
Finally, you said in your question that you've installed the Keil IDE. While this is a fine and rather popular IDE, I'd suggest that you learn using a gcc-based command line toolchain. There are a staggering number of ways in which things that can go wrong when working with embedded systems, and an IDE adds a layer of magic on top of everything that happens. While this can be nice, I'm a strong advocate of minimizing the magic when trying to learn the system. You need to understand the low-level stuff when things don't work automagically. This advice doesn't apply when using the Arduino, which is designed to (and does) make all of the automagical stuff work well.
sparkfun.com has a lot of boards, arduino family and other. I recommend the armmite pro, the lillypad instead of the arduino pro because there is no soldering involved, for either you will need/want the correct usb to serial/power. The mbed2 costs a little more, the blue leds are brutal on the eyes, but easy to use. For none of the above are you required to play in their sandbox, you can use the canned environment, etc but not required.
if it is linux development you are after I recommend the hawkboard.org over the beagleboard.org, to make the beagleboard useable costs about twice as much as the board itself, the hawkboard is usable by only buying something to power it. But you can just learn linux drivers on your desktop/laptop and dont need to mess with embedded necessarily.
Emulators are a good start. Qemu is good stuff, emulates a number of processors, great for emulating virtual linux systems, learning linux driver development, etc. But getting visibility into what the (virtual/emulated) processor is doing is not the goal. I find it useful to have visibility. gdb includes a few emulators as well. mame is loaded with them, but like qemu designed for fast emulation and not for education. visual boy advance is good. Emulation is never perfect, so eventually you want to run on hardware, but emulators and compiler tools are free and you can learn quite a bit before you have to buy hardware. There is a considerable amount you cannot learn from an emulator though, loading your programs into flash/ram, debugging using jtag or other interfaces. i2c, spi, etc.
Our company is using some software that ONLY accepts input from an "Imaging Device" i.e. a TWAIN device (e.g. scanner).
The problem is that we are receiving our files digitally, so using an actual scanner would require us to print, scan, and shred documents that we already have on the computer, but not in the software.
I was curious if anybody has any idea of how we might be able to work around this problem in the meantime. My first thought was to find some way to trick the program into thinking we're using a scanner, via some new 'imaging device' that would just read in the file, and spit it out to the software, but I don't even know where to begin with that.
We put in a feature request, seeing as how this problem should obviously be addressed in the software itself, but the company is notorious for lagging pretty hard when it comes to updates.
The system used by scanners is called TWAIN, so you'd be looking for some sort of virtual twain driver.
A quick google search will produce several hits, I don't have any experience with the software myself so can't advise any further.
Two such providers I found via experts exchange:
http://www.twaintools.de
http://www.scanpoint-usa.com
OK, months late... but in case you are interested, I have a TWAIN driver framework/toolkit that might let you build this fairly easily, depending on just what your scanning app expects, and how hard it is to read images from your digital documents. It's a Microsoft Visual C++ project. No charge but you'd need our permission to redistribute a driver based on it: GenDS
The TWAIN Working Group also has a sample/skeleton driver, I think it's straight C - and used to have some rather bad bugs (Why I wrote mine ;-) but, it might have got better.
Look for the "sample data source and application" on their download page.
And of course I have a 'commercial' version of GenDS that I use to write TWAIN drivers on contract.
