Thanks in advance Lodo JM, thanks for your help with this Good point about the 7 bit address, I have fixed that, but it still doesn’t work.

Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond You probably want to set it up for continuous conversion mode — you don’t seem to be doing that in your code.

I’m new at the microcontroller stuff and would rather it worked at the command line if I can get it to do so. Using the DS in DS dw1631 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. 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. Anything else I can try? It’s too long to post, however, and I can’t fins a way to attach it.

The temperature datashee time is a measure of how long the sensor takes to respond to de1631 request from the host circuit and includes the time required to acquire a temperature reading and convert the temperature reading into a binary word. 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.

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.

I’m not that familiar with Wire.

I2C not working | PIC18F46K22 + DS Temperature sensor | Microchip

Will Microchip’s I2C generated code be as universal as expected to work with this kind of device? Forums Posts Latest Posts. I’ve tested my board with a previous controller and I know the hardware is working. Essentials Only Full Version.

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

DS or B4 AG thanks again for your help, isaac. One question that came up for me while reading dwtasheet datasheet is whether the 2-wire serial communication scheme the chip uses is equivalent to and compatible with the I2C protocol. Also, the Start Conversion command value is different. 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. This application note describes the differences and similarities between the two parts including Daatasheet functions that allow compatibility with the DS but which are not documented in the DS data sheet.

I also tried with code examples that I found on the internet that acted directly on the ports themselfs without setting up I2C module d1631 isbut could not get that to work either, so I opted for MCC code since I believed it to be the most reliable solution. My original question was, “Can you tell me how you have it wired?

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. I have used both with the SX28 and find the DS a bit easier. After struggling through understanding the wire. 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. I keep it simple by reading just one byte back; this is the whole degrees C value. Again, just an easy demo to get connected to the DS 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.

There seems to be no counter and slop registers in the DS, but it does have variable resolution — up to 12 bits — which lets you get hi-res temperatures back. Temperature conversion time is dependent on the resolution selected and ranges from You may set any value up to: Looks like you are trying to use the I 2 C library to talk to it?

I remember hearing that licensing issues around the I2C trademark mean that many manufacturers that produce compatible devices refrain from referring ds16311 them by that name.

The data sheet shows how.

This sensor dataaheet a two-wire serial interface that is funcitonally equivalent to I2C for reading and writing data. Since the Arduino has the 1-Wire library and I’ve written a full-blown program see aboveI’d suggest using the DS You change the resolution via bits in the configuration registers.

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. You may contact me at jon.

I would suggest trying A quick glance at data sheets hint, hint suggests that thought DS and DS are dataasheet devices, they’re miles apart as far as interface goes. I’ve tried for days now and still can’t make this thing to work! After the second entry in the interrupt function:
