l Robot? Bob Stanneveld8-Dec-05 2:30 Bob Stanneveld 8-Dec-05 2:30  Hello all! As I'm looking for a new hobby to spend the little time I have, I came across some nifty embedded systems at some mechatronic labs here at school. Being educated as a technical embedded systems programmer, I thought that it would be nice to build some hardware myself. After some thought, I chose a robot as my first undertaking to get into this. Right after I decided this, I found my first problem: where am I going to get all the hardware? Since there are is a lot of crap out there, I must carefully choose my tools. Some of the things I need are: <list> Microcontroller with C++ compiler Servos Pneumatic or Hydraulic cilinders etc.. So my question to my fellow geeks out there: do you know some good stores for me where I can get all of this stuff? Thanks a bunch!

The PIC's and Motorola HCxx will have the cheapest test/eval boards for development and open source or inexpensive compilers. If your looking for more brute force, you can always get student discounts. I.e. ARM risc processor compilers are around $500 for student discount. -good luck Re: l Robot? Bob Stanneveld8-Dec-05 10:46 Bob Stanneveld 8-Dec-05 10:46  Hello, Thanks for your answer. I'll look more into this micro controller business and see where I can get a decent one that fits into my budget. I still have to see what my budget will be...

But i prefer that u get some Kit and then start ur work ,that will be fine and worth the expense Vikas Amin Embin Technology Bombay vikas.amin@embin.com Re: l Robot? Bob Stanneveld27-Dec-05 6:43 Bob Stanneveld 27-Dec-05 6:43  Hello, Thanks for your information. The 8051 series sounds nice and I have some experiance with them from college. I failed to find a C++ compiler for the board.. I'll probably have to get some decent budget for this undertaking of mine and I assume that it is an almost once-in-a-lifetime purchase, so I better do it good.

We've purchased alot of our robotics components from them. Of course, there are alot more resources, but it just depends on what exactly you're looking for and where you live. Re: l Robot? Bob Stanneveld11-Dec-05 4:35 Bob Stanneveld 11-Dec-05 4:35  Hello, Thanks for your answer. I live in Holland and I'm now making an inventory of what I need and I have to get a budget..

I'd like to write a toolkit that would allow to work with fingerprint device. Such functions as getting the finger image from the device, matching with other, save in database etc. I have a device and driver for it. Maybe you can give some tips what to do for achieving this. I've disassembled the driver's "*.dll"s and found functions that might be necessary, but I don’t know how to work with them...

No mouse motion, no button response. LED still shining. I've found that unplugging it and replugging it (it is USB) will temporarily fix the problem. It may fix it for 5 minutes to 4 hours. I've trimmed all unnecessary tasks in Task Manager, looked into 'Run' in Regedit and cleaned that up a bit, but nothing looked wrong, and cleaned the dust-bunnies out from in front of the LED. The problem even recurred when I had the mouse plugged into another USB port after doing all that. What else, or does it sound like the mouse is ready to die?

Re: Mouse locking up Dan Neely1-Dec-05 7:12 Dan Neely 1-Dec-05 7:12  do you have a 2nd pc to test the mouse on? That'd help localise the problem. You could try using a differnt mouse as well. Re: Mouse locking up David O'Neil1-Dec-05 9:00 David O'Neil 1-Dec-05 9:00  I don't have either, unfortunately. Thanks for replying, though. David inline dont work in VC++ vikas amin25-Nov-05 1:51 vikas amin 25-Nov-05 1:51  I have a simple qestion that when we make a function inline then the code should be embeddede in the main function and we should not have any call done to the function . But actully in VC++ this dont happen pls try the example , and let me know that if am missing to set any compiler flag . In VC++ __forceinline is used to force inline function by passing the cost/benefit analysis .I have tried that also but it dont work . To test the code just go to the disassembly and if u find any assembly instruction as "call" then the inline mechanism is not implement by ur vc compiler . Thank you Vikas Amin Embin Technology Bombay vikas.amin@embin.com Re: inline dont work in VC++ toxcct30-Nov-05 0:15 toxcct 30-Nov-05 0:15  what a C++ question do in a hardware forum Mr Amin ??? did you lost yourself into this deep deep dark website !? moreover, ,if i well remember,, this is a repost... maybe that's why you asked it here (to hope me not to see it but you missed it ) TOXCCT >>> GEII power [toxcct][VisualCalc] -- modified at 6:15 Wednesday 30th November, 2005 Re: inline dont work in VC++ Bob Stanneveld7-Dec-05 22:29 Bob Stanneveld 7-Dec-05 22:29  Hello, The inline keyword is a hint to the compiler, not an absolute. The compiler still chooses best whats good for you or not..

See this http://www.codecomments.com/archive292-2004-11-329446.html 2) Functions containing while cycles will not expand inline 3) Functions calling inline functions will not expand inline I think that´s all.

RAM, Motherboard, processor hardware IDs Bilal Farooq14-Nov-05 20:22 Bilal Farooq 14-Nov-05 20:22  Hi, I have developed a WinXP based application in .NET C#. I want to make sure that it only runs on specified set of hardware. It first checks the hardware IDs of motherboard, RAM, and processor. This application compares those values to what it is supposed to run, and then decide if it is a valid set of specs. I can get these IDs from registry but registry could be fooled. What I want is to directly access these hardwares and get the IDs. Could anyone please help me out in this regard? I don't know if it is possible in .NET or I need to write an assembly code for it. Is there some api or already available programme to do so? Thanks Bilal Farooq Need a bit of Help Stylemaster14-Nov-05 1:14 Stylemaster 14-Nov-05 1:14  Hi This is not a programming problem but i dont know where else to turn i need to know what kind of hardware i need to go on the internet with my PSP from home using a telephone line or do i need a satilite connection.

I installed a generic printer so I could see the name of the printer port and then passed USB002 to WriteFile, but it gives me an error and says that the com port does not exist. Has anyone used this cable to send data directly to the printer through the parallel port and if so could you tell me how to do it or give me some pointers. Roger Re: belkin usb to parallel port cable Trollslayer22-Jan-06 6:06 Trollslayer 22-Jan-06 6:06  A Com port is a serial port, not parallel. Did you install the driver for the USB to parallel adaptor (it is NOT just a cable)? The tigress is here
