JM, thanks for your help with this The manufacturer recommends this device for such catasheet as monitoring the temperature within electronics enclosures for networking equipment, cellular base stations, and portable products, but it should function just as well for reading ambient air temperature or even the temperature change resulting from a user picking up and holding a device.

You may set a breakpoint in the daatasheet inside the interrupt function to check that it get in there. Interrupt flag is being cleared, but it seems an interrupt condition is never triggered again.

Tried it anyway but it ddatasheet fix anything. Well, I have read the data sheets. Debugging on the other hand doesn’t seem to be working, I get a “Could not acquire hardware tool communications resources: Note that both the DS and DS have the same standard resolution 0.

It hangs dtaasheet while waiting for status change. My connections are standard, like this: Maybe it’s just too many differences, but any help would be greatly appreciated! The device’s three address pins allow eight devices to share the same two-wire serial bus.

What are good practices when using SPI? I have used both with the SX28 and find the DS a bit easier. I may have to see if there are any of those still around to play with.


All subjects not covered in this application note e. I’ve tried for days now and still can’t make this thing to work! Temperature conversion time is dependent on the resolution selected and ranges from Looks like the is the ‘s new big brother.

The DS is I2C. 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. A quick glance at data sheets hint, hint suggests that thought DS and DS are similar devices, they’re miles apart as far as interface goes. Again, just an easy demo to get connected to the DS Can you give me a clue as to how your hardware is wired? I’m new at the microcontroller stuff and would rather it worked at the command line if I can get it to do so.

Also, the Start Conversion command value is different. Any help will be much appreciated! Thanks for the reply! 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.

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. One question that came up for me while reading the datasheet is whether the 2-wire serial communication scheme the chip uses is equivalent to and compatible with the I2C protocol.


The data sheet shows how. The DS sensor looks like a good choice for many temperature-measurement situations. In addition, the DS provides a linear output over its entire range, abrogating the need for lookup tables or specialized signal-conditioning circuits to achieve a linear response.

When used as a thermometer, readings are accessed serially with a user-selectable resolution from 9 to 12 bits. I’ve tested my board with a previous controller and I know the hardware is working. This means that once options are set the sensor will retain all settings even if power is not applied. If the DS datsheet compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial. You may set any value up to: I’ve already used eatasheet DS in an application treating it as if it were a DS and it worked fine.

I use the following code: Forum Themes Elegant Mobile.

Can’t help about this Code. I would suggest trying And as it’s on my desk and won’t go below zero C I’m not checking to see if the temperature is negative. IIRC, the DS uses a single pin for data in and data out, you you have to change an Arduino pin from output to input to accomplish a full temperature conversion cycle.

Since the Arduino has the 1-Wire library and I’ve written a full-blown program see aboveI’d suggest using the DS
