This means that once options are set the sensor will retain all settings even if power is not applied.

My connections are standard, like this: You may contact me at jon. User Control Panel Log out. This application note describes the differences and similarities between the two parts including DS functions that allow compatibility with the DS but which are not documented in the DS data sheet. This characteristic of the DS means that microcontroller code and host circuits can be more easily ported and adapted without the need to build new conversion tables or take into account circuit anomalies.

It hangs forever while waiting for status change. Hi Mysil, thanks for the reply. Forums Posts Latest Posts. Stick with the DS Hi, Back to some basic questions: Changing ‘status’ to volatile throws a ” illegal conversion between pointer types” warning. What are good practices when using SPI? I’m not surprised that the DS program didn’t run at all on a DS You probably want to set it up for continuous conversion mode — you don’t seem to satasheet doing that in your code.

I may have to see if there are any of those still around to play with. If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial. After the second daatsheet in the interrupt function: I’ve been trying to get my DS to read using the code above and all I get is nonsense — negative numbers that don’t change.


No code, but it does include some waveforms and helpful hints.

I also tried setting baudrate to the lowest possible, no luck Ok I give up Since the Arduino has the 1-Wire library and I’ve written a full-blown program see aboveI’d suggest using the DS Using the DS in DS applications: The slope method is still supported as an undocumented command. There seems to be no counter and slop registers in the DS, but it does have variable resolution — up to 12 bits — which lets you get hi-res temperatures back. Note that both the DS and DS have the same standard resolution 0.

It just fails to include Wiring.

I’ve also be totally unsuccessful compiling this anywhere but in the arduino IDE. Can you give me a clue as to how your hardware is wired? This sensor uses a two-wire serial interface that is funcitonally equivalent to I2C for reading and writing data. Nikel Starting Member Total Posts: Haven’t received registration validation E-mail?

This datwsheet a designer from dedicating microcontroller ADC resources or a dedicated ADC circuit to the job of converting the analog signals provided by other temperature sensing technologies.

Thanks in advance Lodo You should download and study the DS data sheet; it gives you all the information you need to adapt the program above.

Not sd1631 that does me much good since I’m just not that good at the electronic stuff — more a programmer, unfortunately. I use the following code: The sensor itself is working it’s on a small separate boardI have tested it with a previous controller board and it works. I’m new at the microcontroller stuff and would rather it worked at the command line if I can get it to do so.


I have used both with datsheet SX28 and find the DS a bit easier. I’ve already used the DS in an application treating it as if it were a DS and it worked fine.

The other attractive feature of the I2C version DS is that you could connect up to eight of them to the Arduino with just two pins; to connect eight DSs to the Arduino you’d need five pins and a 74x 3-to-8 decoder to handle the chip select called RST on the DS Forum Themes Elegant Mobile. At the heart of the DS is a bandgap-based temperature sensor. The serial protocol used also allows up to eight of these devices to share a single two-wire serial bus and allows the designer the freedom to place temperature sensing components at a distance from the host circuit if desired.

Temperature conversion time is dependent on the resolution selected and ranges from The DS sensor looks like a good choice for many temperature-measurement situations.

Why does my PIC32 run slower than expected? All subjects not covered in this application note e.

Again, just datssheet easy demo to get connected to the DS I keep it simple by reading just one byte back; this is the whole degrees C value. Yeah, using leds for debugging each step is what I usually do too No Slew Rate Control: Tried it anyway but it didn’t fix anything. It’s too long to post, however, and I can’t fins a way to attach it.
