Hi dazheng,
Need to know ... what is EEPROM used in MCU for ?. I know EEPROM stand for Electrical Erasable Programming ROM but I need to know what's the purpose or where it going to be used in MCU?
I ask this because some of MCU dont have EEPROM ( EEPROM = 0 byte) ie 80NC535 & 80NC321 and the best thing about this MCU (without EEPROM) that's its cheaper than MCU with EEPROM. If it just minor used and can solve it in other method (and not effect my project) , I will use it as I need to lower the cost as much as possible.
Any instruction (ie in proton) that must be used on MCU with EEPROM ?
More explanation greatly appreciated.
Thanks

Hi "zuisti",
She wants the EEPROM for keeping the program when changed.
Will flash Magic Support this one ?
I happen to have a few pieces of this controller!!
I'm ready(?) with this work yet. It is a two mode (switchable) 8 char dot matrix display, working in Proteus, with source in javaC: I'm used a 89c734a.
- in scrolling mode it has a buffer for a max 54 chars message. The speed is controllable. - in static mode it is cascadable, set the position in the received string with the pos. switch.
The attached ZIP contains the orig. article (a PDF), as my start point. Please read it!
Please post here your minds!
"She wants the EEPROM for keeping the program when changed."
No, she doesn't. I checked with her and she wants it for calibration data storage.
can iuse 1-wir eeprom to store cfg dta for signle strand?
"??? why the trollops keep trying to hyjack our project thread ???"
That brings up a really interesting question:
Why are we morons not using e-mail, blogs, social networking websites, etc. for our idiotic project discussion?
"can iuse 1-wir eeprom to store cfg dta for signle strand?"
Absolutely! We use FPGA on source end of all the strands and clock a 1-bit transaction on the strand when the strand's signal crosses zero. On the other end, each strand has it's own 1-wire slave; EEPROMs, MCUs, etc. The throughput is really pretty good overall. Obviously the higher audio frequencies do better.
"... each strand has it's own 1-wire slave ..."

??? why the trollops keep trying to hyjack our project thread ??? if you, for your private discussion had used the appropiate media (e-mail) nobody could have "hjacked your project thread"
i think we must use the secret code to hide detail or they will copy our ideas. what ideas? that a square wheel is better than a round?
The problem to solve is: The speakers have two stereo inputs. One for low frequencies, one for middle rage frequencies and one for hight frequencies. I knew it was bad - but not that it was this bad 1+1+1 = 2 ????
i know you are good strong profesional guru that helps again. just about as true as 1+1+1=2

What a relief!
I was starting to think that I've lost touch with modern design techniques.
another day, another week, another woman (hehe)
By the terms "load labeL, solar panel label, batt label' , i mean "load current, solar panel current and battery voltage" ? In the schematic , i are sensing the voltage across R2 which represents the current drawn from the battery. Then i is using a voltage divider to take a sample of this voltage and producing analog sample using an opamp digital amplifier. I feel this circuit can work much better to sense the battery current.I feel it will work better accuracy if R2 is reduced further (at the cost of watterage).
i want to use it for solar charger and controller , if i use this block for detect load label then it will work at real hardware? i am using mcu with lcd display for showing parameter. batt label, solar panel label , load label, and also with sun tracker(not use at this moment) . have u any idea for that type of project.
thanks
I know you've a good programmer and understand lots, but i've found an artic that you will like to become king master guru !
its advanced c pointer use and how to explain arrays;

I read some but got lost.i am not such goodd programmer as you mate.
readn and learn lots mate.
Oh No! - don't let him loose with pointers...!!

You're quite a butcher, I must say.
"i are sensing the voltage across R2 which represents the current drawn from the battery. Then i is using a voltage divider ..."
s/i are/I am/ s/i is/ I am/
"... further (at the cost of watterage)."
s/watterage/wattage/
"i want to use it for solar charger and controller , if i use this block for detect load label then it will work at real hardware?"
Is that a statement or a question?
"but i've found an artic that you will like to become king master guru !
">www.gamedev.net/.../article1697.asp"
You're kidding, right? With errors occurring in the very first code snippet in Chapter 1, I didn't even bother to read further.
"Is that a statement or a question?"
For your reference, that's a question.
And for your further reference, that's a statement.
"By the terms 'load labeL', 'solar panel label', 'batt label' , i mean 'load current', 'solar panel current' and 'battery voltage'"
Yes, that's a great idea - let's just choose some random word like 'label' and use it to mean 'voltage' or 'current' at random.
Why don't you just call eveything "Bruce" to avoid confusion?!
thanks MatE,
briliant article that.i've been wriing me own ones recentkly and hope to put on a website like that; maybe with results of some of our the other work yeah?
fame man! maybe the trollops around here will learn from you're quality investegations.
last problem you know this; I think you are asking for the code which are contained in a matrix form all the dots for a character. I've seen som examples from the web with this codification, I dont know what are you programming ATM, but the codification its universal, keep looking good luck
thanks agaiin for the article. you remember it for the good future yea !
"briliant article that."
Yeah brilliant, mistakes and all. Let's all learn to write bad code. You two are already experts at writing crappy code.
"i've been wriing me own ones recentkly ..."
Oh, please spare us. There's already too much crappy code on the web. Thanks anyway.
"... the trollops around here ..."
Your sister? Where, WHERE!? I am mighty curious to this bushy maiden. Is the circus in town?
