Wireless network | | 01/01/70 00:00 |
assign address to each slave?(with "jumpers") | | 01/01/70 00:00 |
Still you wont know which is which? | | 01/01/70 00:00 |
pay with time | | 01/01/70 00:00 |
not easy | | 01/01/70 00:00 |
or pay with money | | 01/01/70 00:00 |
or pay with money - not a solution | | 01/01/70 00:00 |
Inherently not simple! | | 01/01/70 00:00 |
you cant poll for N number of slaves | | 01/01/70 00:00 |
automatic | | 01/01/70 00:00 |
N? | | 01/01/70 00:00 |
N? - any | | 01/01/70 00:00 |
Ho about this ... | | 01/01/70 00:00 |
how do you propose to do that? | | 01/01/70 00:00 |
have a look at the picture on the website | | 01/01/70 00:00 |
Obviously missing something here... | | 01/01/70 00:00 |
dipswitch my butt | | 01/01/70 00:00 |
it\'s pretty obvious, isn\'t it? | | 01/01/70 00:00 |
first - then | | 01/01/70 00:00 |
Once again you're assuming facts not in evidence | | 01/01/70 00:00 |
The sample is much larger now | | 01/01/70 00:00 |
example | | 01/01/70 00:00 |
Yes, it is | | 01/01/70 00:00 |
I like that ... | | 01/01/70 00:00 |
I Don't get it either. | | 01/01/70 00:00 |
It's reall not that complicated ... but ... | | 01/01/70 00:00 |
Still not with you | | 01/01/70 00:00 |
Slaves to broadcast their presence HOW? | | 01/01/70 00:00 |
Not that difficult | | 01/01/70 00:00 |
Thats fine but what if we have | | 01/01/70 00:00 |
Then you really do need a database! | | 01/01/70 00:00 |
you WILL get in big doo-doo | | 01/01/70 00:00 |
this is absolutely true! | | 01/01/70 00:00 |
You\'ll need lots of switches and lots of ports | | 01/01/70 00:00 |
totally off the rocker | | 01/01/70 00:00 |
How long, at 8kbps | | 01/01/70 00:00 |
Who on Earth wants to do that | | 01/01/70 00:00 |
One has to set limits | | 01/01/70 00:00 |
It does not have to be manual | | 01/01/70 00:00 |
It has its "baggage" | | 01/01/70 00:00 |
no "significant burden" who cares about 'simpler' | | 01/01/70 00:00 |
Maybe we need to bring the O/P back to reality | | 01/01/70 00:00 |
I can't tell | | 01/01/70 00:00 |
I may be slow today.... | | 01/01/70 00:00 |
ARP possiblities | | 01/01/70 00:00 |
Overhead - but possibly not too serious? | | 01/01/70 00:00 |
You may be onto something ... | | 01/01/70 00:00 |
you don't get it | | 01/01/70 00:00 |
How long would it take? | | 01/01/70 00:00 |
quicker than what? | | 01/01/70 00:00 |
Obviously there's a trick involved | | 01/01/70 00:00 |
or ... | | 01/01/70 00:00 |
no patent ... | | 01/01/70 00:00 |
With that scheme you have to skip some | | 01/01/70 00:00 |
easy | | 01/01/70 00:00 |
No ... it means there's nobody at that one address | | 01/01/70 00:00 |
Not an address, an address mask | | 01/01/70 00:00 |
not likely on low-cost RF | | 01/01/70 00:00 |
of course, but nobody woud dream of sending RF w/o | | 01/01/70 00:00 |
Miracle ? , I differ | | 01/01/70 00:00 |
confound it reat the stuff | | 01/01/70 00:00 |
no patent ... And after slaves colliding | | 01/01/70 00:00 |
after each 'find' it get faster | | 01/01/70 00:00 |
the cheap RF links are typically | | 01/01/70 00:00 |
Erik, please clarify one point | | 01/01/70 00:00 |
If one could devise a suitable RF protocol... | | 01/01/70 00:00 |
the key is to know more than is known here | | 01/01/70 00:00 |
confound it can't you read | | 01/01/70 00:00 |
You're assuming facts not in evidence. | | 01/01/70 00:00 |
if a response comes, your code is faulty | | 01/01/70 00:00 |
So ... how does that differ from not transmitting? | | 01/01/70 00:00 |
Richard, Richard | | 01/01/70 00:00 |
Yes, but what SHOULD happen? | | 01/01/70 00:00 |
with a mask of zero any unassigned sign sho | | 01/01/70 00:00 |
What is it you are recommending, Erik? | | 01/01/70 00:00 |
Nothing I feel | | 01/01/70 00:00 |
Reading Erik's mind | | 01/01/70 00:00 |
Address+Mask - an RF twist | | 01/01/70 00:00 |
let me clarify | | 01/01/70 00:00 |
Russ, I admire your "psychic abilities' | | 01/01/70 00:00 |
A refinement | | 01/01/70 00:00 |
yes | | 01/01/70 00:00 |
Starting over | | 01/01/70 00:00 |
Russ, you may very well be right | | 01/01/70 00:00 |
Erik, that is not what was asked for! | | 01/01/70 00:00 |
whic i would have done ... | | 01/01/70 00:00 |
Perhaps you\'re not aware ... | | 01/01/70 00:00 |
1) abd 2) | | 01/01/70 00:00 |
NOT "mask address" but "mask AND address" | | 01/01/70 00:00 |
some things you can do on the one-wire channel | | 01/01/70 00:00 |
Very tricky indeed | | 01/01/70 00:00 |
I do not ASS U ME diddlysquat | | 01/01/70 00:00 |
It is absolutly required for my scheme | | 01/01/70 00:00 |
That is a non-starter with low-cost RF. | | 01/01/70 00:00 |
sorry | | 01/01/70 00:00 |
OK, here's an idea | | 01/01/70 00:00 |
collisions avoidance ? | | 01/01/70 00:00 |
Surely the master needs to know its slaves?! | | 01/01/70 00:00 |
identifying slaves | | 01/01/70 00:00 |
I can not help with collisions but.. | | 01/01/70 00:00 |
multimaster via RF | | 01/01/70 00:00 |
collision recovery | | 01/01/70 00:00 |
Not a few seconds | | 01/01/70 00:00 |
Listen Before Xmit | | 01/01/70 00:00 |
not that urban legend again | | 01/01/70 00:00 |
Accepted terminology | | 01/01/70 00:00 |
Collisions will still happen | | 01/01/70 00:00 |
Yes, but how will the system respond? | | 01/01/70 00:00 |
Listen Before Xmit ...... | | 01/01/70 00:00 |
if slaves can "speak without being spoken to" | | 01/01/70 00:00 |
Perhaps you should read this article | | 01/01/70 00:00 |
A Better Way | | 01/01/70 00:00 |
There are some internal issues too | | 01/01/70 00:00 |
frequency hopping | | 01/01/70 00:00 |
frequency hopping , I have DSSS | | 01/01/70 00:00 |
