Re: One Wire - MAX1454

I've talked with MAXIM and they refer to the MAX1454 as a One Wire device even though the data sheet doesn't explicitly state this. Pin 12 is Multiplexed as both the Analog Output and the Digital Input/Output pin of the 1 Wire communication. https://datasheets.maximintegrated.com/en/ds/MAX1454.pdf ...

Thanks. Looks like they are all old Dallas Semiconductor devices, https://owfs.org/index_php_page_standard-devices.html. None of the Maxim One Wire devices.
In the datasheet of MAX1454 didnt pointed aot that it can work with 1-wire interface. Mothing. :?: :arrow: :!:

Re: One Wire - MAX1454

You can see official site OWFS - https://owfs.org/ if you find your chip in list of supported chips - yes you can do it.
If not -not.

Re: Dallas OneWire Ds2413

Hello, I apologize if this has been answered in another thread but I've searched for days and found nothing concrete. Does anyone know of any libraries to read and write to the DS2413 breakout board from Adafruit? I can see the device in the devices folder and turn on either or both outputs, and tu...

Re: how connnect 4 or more ds18b20

It has to be how you are connecting the 4,5,6 sensor, because you say you have checked the individual sensors and they work. Try replicating your wiring in a smaller scale say a foot of cable then if you still can't get it to work post some pictures and may be we can spot the problem. please see ti...

Re: how connnect 4 or more ds18b20

Vdd should be connected to 3.3V, not 5V! For long runs that need more power you can connect Vdd to 5V but have the 4K7 resistor between Data and 3.3V. The data line should never go above 3.3V or it could kill the Pi. my problem asnot in voltage, i assemble long wire with four ds18b20 and i have sho...

It all depends in which network the Pi is located. For my answer I'm going to assume that the Pi is located at your home and that you have a standard broadband connection with a router delivered by your internet provider. To let the incoming traffic reach your service you have to open/forward the c...
