Cant we do this?

[drwayne]

I heard that tv show has great ratings lol. Ill try to send another pic. How long does stuff take to get here from there.I also have to ask you this cause i see it in outback steakhouse what the hell is a bloke? I mean is that a direct interpretation for the word man?Also this is way off subject. Ever seen an inland taipan?

7-10 days average.

A bloke is .. a classic Aussie male.. crocodile dundee sorta character exaggerates a lot.. but thats the image... easy going , not concerned by much
Cripes... Steve Irwin is an Americanized for TV version of a 'bloke'.. he spoke too much, wouldnt leave nasty things alone.. .. and took his missus fishing !

The Taipan snake is fast .. and it lucky4me prfers to be some 1500 miles NE from my doorstep... where the greater prevalence of overseas tourists visit, offering numerous snacks to the faster local reptilians.

Wayne if I get this high voltage esc built. Can you write code for me? The microproccesor will likely be in the pic dsp family 18xxxxseries pic or a parallax propeller chip

Aww, that's cheating !



The mechanics of a circuit are @90% the work.. the code is the other 50 % !!
This is what makes everything work.
You need to design hardware mutually with code script.. and satisfy both to suit the other.
It is not a case of 'here is the fet array, write me a driver.'

Research something basic like a HC6811 and scale up from there.

I could certainly read your scripts and point, cough or smile at what's wrote..

Advise is free from my slowly replenishing pool of wordswise.. alas drink deep too often and the pool runs dry !

Im sure you understand that addendum ..........

cheers

Wayne why in the world would u want me to fool with old 6811 stuff. Ive already have experience coding pic, cplds, 8051/52,basic stamp,etc. I just hate to type period. lol

A pic 30f2010 is more what im thinking of it desingned for brushless motor control it 40 mips fast and has 8 motor control outputs as well as a input for qudrature rotary sensor> Im just worried about money for compilers for this chip I have none . The only programmers I have now are pic 18pin and atmel 40 pin .So ill have to borrow that from the school if I can.Check that pic30f2010 chip out and tell me what you think?

Get the eval copy!

He's right, though. You work on both hw and fw at the same time when you're developing this stuff. Actually, working on the code first helps because you define pin usage correctly then :)

Im aware of that andy I just dont like type once again.Please listen. when I tell you I know something I do . Im totally aware of defining pins and what not. Did you read what I have experience in programming? Do you think I could go through all the course work and not know that the programmer would have to know what was going on with the hardware to program the code? All of them basically work the same you read their bible figure out the syntax it wants and program it, I get and have much experience with all of that daily. Code is coming out my ears. I dream of the A-register lol.I know logic okay too boolean algebra karnaugh maps all that mess. And I can do altera cpld's as well. I just hate typing code. Besides they have sample code if you build the example schematic but its very basic. I was doing like wayne said; trying to cheat and save myself some time.I think that closed loop/locked rotor code might get a little hairy for me. I dont want to do all that typing.Ive also already gone through digital. Electronics Communications was hairy with all the trig but I squeezed a b outa that course too. An "anstrom" I learned all that junk dont remind me eek.

You need someone on your doorstep everytime you seek a change...
Lots of comparative tests and instant entropy give datalogs from where code can be based

If your competency is as large and bold as your enthusiasm.. There is likely a competent code writer eagerly waiting to partner with your project.
Advertise your need where code writers live and breathe.. this electric boat forum does not seem to be where we exist in abundance... !

Me.. write code for you.. no, not practical from Oz.

Stay in touch

The nice part about code is you can often copy and paste. That doesn't work so well for English.

Please listen. when I tell you I know something I do . Im totally aware of defining pins and what not. Did you read what I have experience in programming? Do you think I could go through all the course work ...

Course work and reality are quite different.

I just hate typing code.

VB will type it for you. :grin:

Ive also already gone through digital. Electronics Communications was hairy with all the trig but I squeezed a b outa that course too. An "anstrom" I learned all that junk dont remind me eek.

I live in the digital world. It's a cool place. What's really interesting is where it interfaces to the analog world. And that's what an ESC is.

Some of the app notes are far from basic.

Talk to Jim Drew at XPS. You can find him on RCGroups.com

When I was in college, I had a good buddy. We would team up and accomplish all kinds of neat stuff together. Got anybody in your classes you can do that with?

I ahead of most of the guys because of all my prior experience see I went to OU back in 90 and started there plus Ive just always fooled with electronics even as a kid.My dean will help me but he stays so busy . the school is going through alot of transitions, upgrades,etc. Andy I hear you but im good dont speak on the course work until youve had TIM WOO a chinese instructor that drives and pushes you into the ground. Repetition ,repetition,repetition.

[Xfactor]

Analog is more challenging for you too andy not just me the world.Ive already aced physics and ic's all really left before I transfer to nc state is op amps and maybe a troubleshooting course thats y im trying to keep tha gpa as high as possible.

[AndyKunz]

Yes, a high GPA is very helpful. I ended up with a 3.86/4.0 when I graduated from UNC-Wilmington with a double CS major and math minor. It definitely helped when I went to my first job. After that it didn't matter much to employers, but it still helped me in that I had mastered the subjects.

We had one prof (booted from UNC-CH to us) who taught in German, gave handouts in German, etc. I had the highest score in his class - 30%. Lucky for me my mother grew up in the same city as he did so I used brownie points.

As for electronics, I tested out.

As a freshman.

Dr. Doom (that's what we called the prof who did most of the electronics courses) wasn't pleased. Later we were friends.

I think you need to "tim woo" yourself on this stuff before you bring it here.

Well I tastfully disagree cause this is my thread and since the start youve been trying to get me to stop well Im not so ... If you dont like what I brought then of course you dont have to read it theres always that option. I think Im getting the help I need now thank you sir.Im no competition for your company so no need to lobby for them.Thats really good u tested out but I wanted a solid foundation so I opted to start over from scratch. Not trying to be smart but if every other reply after waynes gonna be negative please leave this foolish student (me) alone thanks.

[Xfactor]

You can only copy and paste whats been written already so for all the fine details ill still have to write code. Wayne Ill pm you .Luckily I have to earn every grade no brownie points and nc states the top state run engineering school in nc.So ill woo woo myself there.Thanks Dr.

[drwayne]

The Thread subject is "cant we do this?" and yet you argue on with "I" this and "I" that.

Your education background seems sound and predominantly qualified for the project's parameters you talk of.
Your current study topics equally so.

The one common thing coming from all respondents here is this...

esc design is not a simple task.

I personally dont care if you have a gpa of 4.. or are a school dropout "idiot savant" gifted in electronics. !
Ive acknowledged a few of each in my years, and am satisfied both talent sources are worthy.

Stop talking about doing this, and get on with it !

Easy start ... grab a small chunk of paper and work out budgets.....
hw, fw, r&d. ......
Admit it ... you need a sponsor/partner.!
So it is indeed a "we" thing.

err.. "we" does not include "me".

We're now limited to 24hrs each day, down here in Oz.
Im sure the govt have reduced the hours due some budget cutbacks....
I use to do so much more between breakfasts ...
(maybe I sleep too long?.. nope )
There's just not as much spare time for life outside of work these days...

but I do like my job :)
