I’m new at the microcontroller stuff and would rather it worked at the command line if I can get it to do so. Looks like you are trying to use the I 2 C library to talk to it?

Forum Themes Elegant Mobile. The device’s three address pins allow eight devices to share the same two-wire serial bus. Hi, Back to some basic questions: This application note describes the differences datashedt 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 use the following code: 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.

You may set a ds131 in the debugger inside the interrupt function to check that it get in there. You may set any value up to: Why does my PIC32 run slower than expected? Forums Posts Latest Posts. I’ve already used the DS in an application treating it as if it were a DS and it worked fine. If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial.

Nikel Starting Member Total Posts: After struggling through understanding the wire. The manufacturer recommends this device for such applications 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.


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

Again, just an easy demo to get connected to the DS The DS and DSA sensor families exhibit similiar characteristics and operations but with a few differences – see the relevant datasheet datsaheet these devices for more about their operation.

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. The DS is I2C.

Maybe it’s just too many differences, but any help would be greatly appreciated! User Control Panel Log out.

I2C not working | PIC18F46K22 + DS1631 Temperature sensor

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. It’s too long to post, however, and I can’t fins a way to attach it. The DS sensor looks like a good choice for many temperature-measurement situations.

The DS measures environmental dtasheet and provides temperature readings serially to a circuit. Temperature conversion time is dependent on the resolution selected and ranges from You change the resolution via bits in the configuration registers. 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.

Can you give me a clue as to how your hardware is wired? 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 datadheet 74x 3-to-8 decoder to handle the chip select called RST on the DS 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.


Read out of DS I’ve tried for days now and still can’t make this thing to work! At the heart of the DS is a bandgap-based temperature sensor.

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

JM, thanks for your help with this Changing ‘status’ to volatile throws a ” illegal conversion between pointer types” warning. Yeah, using leds for debugging each step is what I usually do too Can’t help about this Code. I’m not that familiar with Wire. Ok I give up You probably want to set it up for continuous conversion mode — you don’t seem to be doing that in your code.

The data sheet shows how. I also tried setting baudrate to the lowest possible, no luck 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.

Sensor Workshop at ITP :: Reports / DS

What are good practices when using SPI? An analog-to-digital ADC converter with user-selectable precision references this sensor and converts its output to a digital word. I may have to see if there are any of those still around to play with.

Using the DS in DS applications: The benefit of this type of temperature sensor over others is that it directly provides a serial representation of temperature in a relatively small package size. 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.

Stick with the DS I’m just learning C, so this one is probably better it’s certainly trimmer than what I had yesterday Also, the Start Conversion command value is different.
