The ds18B20's are brilliant, and it's dead easy to address them from the pic all you need to find is the matching rom address for each device then talk to each one whenever you want :)

Anyone used one of these?
What I'm trying to find out is what happens if power is removed, does the time stay stored or does it lose power?
also anyone seen these anywhere in UK?

DO you reckon I could use that, but still have enough time to poll 4 1 wire devices and keep the clock running?...

how about using the eeprom inside the pic?
I'm going to be suing the 16F88 pic it has 256 bytes of eeprom and 20000 hours counted once a second only comes to 33 bytes if I'm starting to understand...

I'm actually going to be using 2 X ds2405's as switches to work relays along with 2 ds18b20's as temp sensors
What I'd like to do is log the total amount of time the ds2405's are activated and...

Anyone got any ideas how to implement "powered on/run time" in a 1 wire network? All I need is the amount of hours and minutes it's running, in fact it can be just one device that I time as it's...

or at least very hard!

Hi guys...

my pin assignments are:
RS PORTB.4
E PORTB.5
but the data lines are
PORTB.0 LCD D7
PORTB.1 LCD D6
PORTB.2 LCD D5

Totally perfect thanks :)
not sure if I'll buy the usb adaptor or just make the interface yet but really good info and exactly what I was looking for
I would just make an interface but it's going...

THINK I've sussed a bit more:
IF I want to change the resolution from the default I can use something like

OWOUT DQ, 1, [$CC, $4E, 0, 0, $5F] ' 11 bit resolution

and to address individual...

Thats fine thanks :)
Actually I've only skipped through the manual to bits I really need to research that I cant find answers elsewhere, but I found the easiest and best way to learn was study other...

Am I right in assuming IF i dont use the constants then it would default to 0.0625°C resolution and take 750ms to take a reading?
BUT IF I want to change the resolution I'd use the constants, but...

Thanks, that actually helped a LOT, even though it threw me at first and I had to read it several times...

Has anyone any suggestions on how to read the id code from 1wire products?

No that was one I missed actually, many thanks, it's good interesting reading, Melanie must be a complete genius :)

I've seen many examples of code for the DS18B20 and I've successfully made it work before
However there is one thing I dont understand and could someone please explain it to me?
IN this code

Changed it thanks. Hopefully it's right now.

Anyoe know how I program it so the mclr input only works as an input pin and not mclr?
still stuck on the ds too


CCP1CON = %00000000 ;...

AHH now that makes sense.. I just wasn't sure what I should do with the pics when using them as ext OSC
Thanks:)

Apart from that, does the code look ok?
and any ideas on how to set the higher...

Think i MIGHT have that sorted now:)

CCP1CON = %00000000 ; Disable CCP Module

Hi all, and before I go any further I want to say thanks to everyone who has helped me before :)
The previous problem I had about trying to work a serial LCD, I've left that to one side for the...

Thanks guys, you've been a great help :)
I'm going to try building my own and it will take me some time to get it working but I'll persevere

I'm still lost in a world ruled by machines :)

But on the 2nd pic it receives serin...
