The DS sensor looks like a good datasheeet for many temperature-measurement situations. The data sheet shows how. Read out of DS Good point about the 7 bit address, I have fixed that, but it still doesn’t work. I stand corrected – I never realized datasheeg was I 2 C. Nikel Starting Member Total Posts: Can you give me a clue as to how your hardware is wired?
The precision, range, and accuracy promised by the datasheet should be suitable for most typical applications and the response time, especially at 9 bits of resolution, should be fast enough for near-real time sensing. Changing ‘status’ to volatile throws a ” illegal conversion between pointer types” warning.
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.
Mysil Super Member Total Posts: The DS measures environmental temperature and provides temperature readings serially to a circuit. At the heart of the DS is a bandgap-based temperature sensor.
The sensor itself is working it’s on a small separate boardI have tested it with a previous controller board and it works.
Maybe it’s just too many differences, but any help would be greatly appreciated! Since the Arduino has the 1-Wire library and I’ve written a full-blown program see aboveI’d suggest using the DS The slope method is still supported as an undocumented command. 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.
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. I’ve tested my board with a previous controller and I know the hardware is working.
I2C not working | PIC18F46K22 + DS Temperature sensor | Microchip
Anything else I can try? The DS is I2C. I use the following code: Interrupt flag is being cleared, but it seems an interrupt condition is never triggered again. Forums Posts Latest Posts.
Using the DS in DS applications: No code, but it does include some waveforms and helpful hints. This sensor uses a two-wire serial interface that is funcitonally equivalent to I2C for reading and writing data. If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial.
You should download and study the DS data sheet; it gives you all the information you need to adapt the program above. Ok I give up 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.
I also tried setting baudrate to the lowest possible, no luck Essentials Only Full Version. 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 dataasheet binary word.
Can’t help about this Code. Thanks for the reply! 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.
It hangs forever while waiting for status change. 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.
After the second entry in the dataaheet function: Yeah, using leds for debugging each step is what I usually do too Thanks in advance Lodo I’m just learning C, so this one is probably better it’s certainly trimmer than what I had yesterday Forum Themes Elegant Mobile.
No Slew Rate Control: I have used both with the SX28 and find the DS a bit easier. 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 just fails to include Wiring. 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. 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.
I don’t think the DS vs the DS should matter as I’ve made that dataaheet before and they’re supposed to be pin compatible. I’ve already used the DS in an application treating it as if dtasheet were a DS and it worked fine.
