You may contact me at jon. 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.

DS1631, DS1631A, DS1731 High-Precision Digital Thermometer And Thermostat

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. Maybe it’s just too many differences, but any help would be greatly appreciated! I use the following code: It just fails to include Wiring. The data sheet shows how. My original question was, “Can you tell me how you have it wired?

DS1631 Datasheet

I stand corrected – I never realized it was I 2 C. If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial. Stick with the DS Note that both the DS and DS have the same standard resolution 0.

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.

When used as a thermometer, readings are accessed serially with a user-selectable resolution from 9 to 12 bits.

I also tried setting baudrate to the lowest possible, no luck In thermostat mode, the sensor is pre-programmed by the user with upper and lower temperature limits and will change the state of output pin Tout when one of these limits is reached. After struggling through understanding the wire. 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.

Can’t help about this Code. Datashset probably want to set it up for continuous conversion mode — you don’t seem to be doing that in your code. Tried it anyway but it didn’t fix anything. Haven’t received registration validation E-mail? Interrupt flag is being cleared, but it seems an interrupt condition is never triggered again. Again, just an easy demo to get connected to the DS Good point about the 7 bit address, I have fixed that, but it still doesn’t work.

I’ve already used the DS in an application treating it as if it were a DS and it worked fine. Hi, Back to some basic questions: Debugging on datasjeet other hand doesn’t seem to be working, I get a “Could not acquire hardware tool communications d1631 The DS measures environmental temperature and provides temperature readings serially to a circuit.

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. Ok I give up Mysil Super Member Total Posts: 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. All subjects not covered in this application note e. After the second entry in the interrupt function: Changing ‘status’ to volatile throws a ” illegal conversion between pointer types” warning.

This sensor can be used to monitor the temperature of an area or object and to either provide temperature information to a circuit or trigger some action when a certain temperature is reached.

Not that that does me much good since I’m just not that good at the electronic stuff — more a programmer, unfortunately. This frees 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. Anything else I can try? Essentials Only Full Version. Yeah, using leds for debugging each step is what I usually do too Temperature conversion time is dependent on the resolution selected and ranges from 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.

I don’t think the DS vs the DS should matter as I’ve made that switch before and they’re supposed to be pin compatible. You change the resolution via bits in the configuration registers. 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.

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.

In the past Ratasheet 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. An analog-to-digital ADC converter with user-selectable precision references this sensor and converts its output to a digital word. 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.

No Slew Rate Control: I may have to see if there dataasheet any of those still around to play with.

The DS is I2C. This is a link to a dropbox zip file with all my attempts dropbox. You may set a breakpoint in the debugger inside the interrupt function to check that it get in there.
