In the past I’ve always also put 5V on the temperature chip before it would work this was using some desktop computer software that bit-banged the serial port.

What are good practices when using SPI? I also tried with code examples that I found on the internet that acted directly on the ports themselfs without setting up I2C module that isbut could not get that to work either, so I opted for MCC code since I believed it to be the most reliable solution.

The DS and DSA sensor families exhibit similiar characteristics and operations but with a few differences – see the relevant datasheet for these devices for more about their operation. Any help will be much appreciated! Debugging on the other hand doesn’t seem to be working, I get a “Could not acquire hardware tool communications resources: I may have to see if there are any of those still around to play with.

Note that both the DS and DS have the same standard resolution 0.

The DS sensor looks like a good choice for many temperature-measurement situations. Looks like the is the ‘s new big brother.


I also tried setting baudrate to the lowest possible, no luck Haven’t received registration validation E-mail? I’m new at the microcontroller stuff and would rather it worked at the command line dataaheet I can get it to do so.

JM, thanks for your help with this Thanks for the reply! I’ve tried for days now and still can’t make this thing to work!

When used as a thermometer, readings are accessed serially with a user-selectable resolution from 9 to 12 bits. You probably want to set it up for continuous conversion dss1631 — you don’t seem to be doing that in your code.

I remember hearing that licensing issues around the I2C trademark mean that many manufacturers that produce compatible devices refrain from referring to them by that name. The temperature conversion time is a measure of how long the sensor takes to respond to a request from the host circuit and includes the time required to acquire a temperature reading and convert the temperature reading into a binary word. The other attractive feature of the I2C version DS is that you could connect up datasgeet eight of them to the Arduino with just two pins; to connect eight DSs to the Arduino datzsheet need five pins and a 74x 3-to-8 decoder to handle the datasheeet select called RST dataheet the DS Yeah, using leds for debugging each step is what I usually do too No Slew Rate Control: 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.


Mysil Super Member Total Posts: In addition, the DS can function in thermostat mode – in this case, the user programs the sensor with upper and lower temperature limits and the sensor changes the state on an output pin when one of the limits is reached. It hangs forever while waiting for status change.

Since the Arduino has the 1-Wire library and I’ve written a full-blown program see aboveI’d suggest using the DS Looks like you are trying to use the I datashee C library to talk to it? When continuous conversion is used you can read the temperature at any time though I believe the first conversion takes about one second to complete.

You should download and study the DS data sheet; it gives you all the information you need to adapt the program above. This is a link to a dropbox zip file with all my attempts dropbox. Dztasheet may set a breakpoint in the debugger inside the interrupt function to check that it get in there.

Anything else I can try? Maybe it’s just too many differences, but any help would be greatly appreciated! If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial. A number of associated components on the chip handle IO and sensor behavior.
