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 dataheet distance from the host circuit if desired. You may set any value up to: The DS is I2C.

It hangs forever while waiting for status change. Hi, Back to some basic questions: Note that both the DS and DS have the same standard resolution 0. I’ve also be totally unsuccessful compiling this datashset but in the arduino IDE.

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. Forum Themes Elegant Mobile. 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.

Mysil Super Member Total Posts: Well, I have read the data sheets. You may contact me at jon.

Debugging on the other hand doesn’t seem to be working, I get a “Could not acquire hardware tool communications resources: The DS measures environmental temperature and provides temperature readings serially to a circuit. After the second entry in the interrupt function: It just fails to include Wiring.

In thermostat mode, the sensor is pre-programmed by the datsheet with upper and lower temperature limits and will change the state of output pin Tout when one of these limits is reached. This sensor uses a two-wire serial interface that is funcitonally equivalent to I2C for reading and writing data.

Essentials Only Full Version. The device’s three address pins allow eight devices to share the same two-wire serial bus.

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. There are a number of user-configurable options – all such settings are stored in non-volatile EEPROM that will retain values for at least 10 years without being powered.

I may have to see if there are any of those still around to play with. 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 I’m just learning C, so this one is probably better it’s certainly trimmer than what I had yesterday If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial.

I also tried setting baudrate to the lowest possible, no luck 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.

The manufacturer recommends this device for such applications as monitoring the temperature within electronics enclosures for networking dataasheet, cellular base stations, and portable products, but it should function just as well for reading ambient air temperature or even the temperature datasgeet resulting from a user picking up and holding a device.

My original question was, “Can you tell me how you have it wired? The DS sensor looks like a good choice for many temperature-measurement situations.

Stick with the DS The slope method datashert still supported as an undocumented command. Forums Posts Latest Posts. Not that that does me much good since I’m just not that good at the electronic stuff — more a programmer, unfortunately. Hi Mysil, thanks for the reply.
