want to know,
what micro controller or controller or whatever processor or small processor that supported by fasm or could be program using fasm although no support.

have any one of you made a board, put a microcontroller, put led, put a port then program in pc, send to micocontroller? maybe put wifi control then use it to broadcast "hello world" or something else?
i want to learn but i don't know how to start Crying or Very sad

any teacher/guider here?

short answer Fasm is afaik for x86 processors only. To program micros you need an IC programming kit PIC's are the most widely used by hobbyists. This is a very expensive hobby especially when you are startin out and dont have most of the necessary equipment.

Are you trying to get into IC as a hobby or just considering the idea

at watever cost, i want to know how to do it. coz i want robot/small device to serve me. and resusing the components from faulty board/monitor to create something useful.
or just a wifi control that could control a motor to move left,right,forward,backward.

the problem is, i don't know how to start Crying or Very sad
the only relevant knowledge i got now is, a little bit asm.

Here you can buy everything you need (in USA)
http://www.radioshack.com/corp/index.jsp?page=store_locator_international
or alternatively (in UK)
http://www.catalogue-discounts.co.uk/pages/?maplins
hint if at any time the salesman offers you a near equivelent because they dont have the exact components (happens all the time) make sure you are already familiar with the alternative parts or you risk short circuiting all you hard work

Here is a little info to get you started
http://www.mstracey.btinternet.co.uk/pictutorial/picmain.htm
http://users.tpg.com.au/users/talking/index_of_chapters.html

and as for robotics
http://www.societyofrobots.com/remote_control_robot.shtml
Take note of the components they mention and find out more about those that interest you and remember to start small

edit -
http://www.play-hookey.com/
This is the best place to start I think with IC it doesnt deal with programmable logic chips just bog standard logic gates but the experiments will give you a solid grounding in what is needed and will introduce you to components that are essential to PIC as well such as the 7805 regulator

Microchip will gladly send you lotsa chips completely free of charge:

http://sample.microchip.com

Don't hurt them, if you don't order anything they may get really sad.

On a side note, at Texas Instruments they are very nice too.. and at Maxim half nice.

I started getting free samples, now I started my own business and am gonna buy 1000's of chips from them. So don't think they're stupid giving away lotsa chips for free, because they definitely ain't. They know how to do marketing.

so nice Smile
so, i think i just make sure what i need first now Wink
coz they got sales office in penang, malaysia (around 45 mins from my current location)
thanks a lot, maverick & tom Wink all links appreciated!!

ok, i think my first ambitious project would be create a LED sign board.
something like here, http://www.led-signs.com/displays/
and maybe i could use like the radio controller / wifi controller to control watever text that should shown there through pc, scroll from left to right or right to left, up to down or down to up.

so, i think i need,
several LEDs
and ...? idk.

zZzzzZzz: I suggest you NOT to begin with the 16F family, it's too outdated. If you want 8bit, begin straight with 18F. But if you can, go dsPIC directly, it's 16bit and has even DSP-style instructions (not the 24F though, where they are stripped).

Start slow and grow a bit at a time. Then throw all your microcontrollers away and go for FPGAs!

Hmm am I smelling 'VHDL' here ?
Very Happy

Wow, sure beats smelling that old soldering gun we used in the 1960's....Do they still manufacture solder? Smile

Ha ha
Yes, solders are still out there
Yet, I prefer not to do the 'dirty works' ... let the electrical engineering guys do that
Simulator works are enough for me Very Happy

God forbids! You are NOT smelling VHDL here, but Verilog!! Wink

For totally noobs in the subject like me I recommend to look that site, I got impressed looking at it. The tutorials are in Verilog which IMHO is easier to understand. There are people that says that for big projects is better VHDL but I can't comment anything about that. Maverick?

here is what i got currently,

i am a little bit confuse on what micro-controller i should get.
PIC ? atmel? or basicx stamp or ...
still research for more info.
and what is fpga? Crying or Very sad Crying or Very sad

Yes, fpga4fun is a very nice site.

I disagree, for me Verilog was better as a start and is still better, until I die and stop. Very Happy

Get a PIC (or, better, a dsPIC), so you can get the chips for free.

FPGA = a kind of custom chip you can make by yourself. A sea of logic gates, so to speak, you decide the interconnessions of. Try Wikipedia.

But there's time.. start with the microcontrollers, FPGAs require good knowledge of digital logic, and definitely serious experience. They are to make CPU's, for example, not "blink a led" projects (although they can make that, too, of course!).

Have fun!

thanks maverick,
btw, i found this really great tutorial for microchip, it uses PIC1648A as example.

http://amqrp.org/elmer160/lessons/
it provides step by step tutorial, really nice!

You need to get MPLAB and a pic programmer, you can buy one or make one
http://www.bobblick.com/techref/projects/picprog/picprog.html
I was thinking about writing one for DexOS (the software), as theres lots of dos examples.
This is some thing, i was thinking about making POV for peoples car weels
See here: http://drewish.com/blogger/archives/2005/03/17/2sided_pov_toy.html

My idea was to make it small enough to screw on the dust caps, about 2 1/2 inch long, with led along it and SM and a small pic.
