Need 8051 Guru for project

Hello Rocky,

Can't help you there but I have forwarded it to a friend who does uCs a lot. Is your email the real one or somehow spam protected?

Long term it will help to build a small network of people with different talents, preferably in your area so you could meet easily. Then you'd be prepared if that situation ever comes up again. Including people with similar talents in your network can also help even though they may be seen as competitors. You never know. Once I had to jump in for an analog guy after a motorcycle crash. But the client turned pale when I told him that I was parachuting ;-)

Hmmmm.... floating point algebra on an 8051 ! It's a great little uC but hardly intended to do that !

I dealt with some issues that might have needed that kind of stuff by using some look-up tables in a 'cute' way.

Can you give a more detailed overiew of the hardware and its application. Is it stand alone btw ?

try a post in comp.arch.emmbeded, they'll surely have some contacts

The 8051 can do anything a Cray can do, it just takes a little longer. I suspect the OP would be happy with fixed point math anyway.

I do that too but I also have stuff like a 32 bit -> 16 bit squarerooter for when smaller is more of an issue than faster.

For arctan, an interpolated table seems to be the best way to go. Calculating one takes a very long time.

Heh. One time, years ago, I had a motorcycle, and I sky-dived. I'll never forget the time I was leaving for the day, and the owner of the DZ said, "Be careful on that murdercycle!"

(i.e., the most dangerous part of skydiving is driving to the DZ on a public road.) :-)

Cheers! Rich

Hello Rich,

True. The only time I ever hurt myself in skydiving was on the way back home, on the rear seat of a friends dirt bike. The foot rests on that seat were fastened to the rear wheel mount and he barreled over a railroad crossing at full bore. Ouch. Limped for days. Whenever I responded to questions that this wasn't related to parachuting people laughed "yeah, right...".

Regards, Joerg

^^^^^^^

The above makes it sound like you landed in the parking lot with a bag of op-amps in your hand. "Hi, I'm the new guy, where's the lab?"

I asked some of skydivers at the DZ I go to if they tell people at their "daytime job" what they do on the weekends. Most of them said they don't volunteer it, but will talk about it if asked.

I think that's true if you drive far enough (like a few dozen miles) and travel through a large, urban area, but it's not always true in general. #include

Hello Matt,

I didn't volunteer either but when in the office of their CEO he said "... but you don't do anything dangerous as well, like riding a motorcycle, do you?". I didn't ride motorcycles but felt that I had to be honest and told him about parachuting. He almost choked. Since there aren't many analog guys around he kindly asked whether I could hold back on it at least until the project was finished. And this CEO had a reputation of a lead foot. On the autobahns any speed below 130mph was a crawl to him. This is the only guy I had ever met who would max out a Mercedes 560S for long stretches.

To me the people in most danger were the skydivers who had lost all fear and pulled at 1700ft and stuff like that.

Regards, Joerg
