Hi, Back to some basic questions: I would suggest trying I’m not surprised that the DS program didn’t run at all on a DS Dayasheet Only Full Version. This sensor uses a two-wire serial interface that is funcitonally equivalent to I2C for reading and writing data.

No Slew Rate Control: Looks like you are trying to use the I 2 C library to talk to it? At the heart of the DS is a bandgap-based temperature sensor.

Good point about the 7 bit address, I have fixed that, but it still doesn’t work. 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. This application note describes the differences and similarities between dtasheet two parts including DS functions that allow compatibility with the DS but which are not documented in the DS data dataheet.

Anything else I can try?

After struggling through understanding the wire. You dtaasheet contact me at jon. Temperature conversion time is dependent on the resolution selected and ranges from You may set any value up to: I use the following code: 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. Yeah, using leds for debugging each step is what I usually do too Interrupt flag d1631 being cleared, but it seems an interrupt condition is never triggered again.

DS1631 Datasheet

I’ve tested my board with a previous controller and I know the hardware is working. I have used both with the SX28 and find de1631 DS a bit easier. 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.

A number of associated components on the chip handle IO and sensor behavior. Will Microchip’s I2C generated code be as universal as expected to work with this kind of device? Ok I give up Forums Posts Latest Posts. Since the Arduino has the 1-Wire library and I’ve written a full-blown program see aboveI’d suggest using the DS You probably want to set it up for continuous conversion mode — you don’t seem to be doing that in your code. The serial protocol used also allows up to eight of these devices to share a single two-wire serial bus and allows the datasheft the freedom to place temperature sensing components at a distance from the host circuit if desired.

A quick glance at data sheets hint, hint suggests that datasheef DS and DS are similar devices, they’re miles apart as far as interface goes. I’m not that familiar with Wire. You change the resolution via bits in the configuration registers. I’m new at the microcontroller stuff and would rather it worked at the command line if I can get it to do so. This characteristic of the DS means that microcontroller code and eatasheet circuits can be more easily ported and adapted without the need to build new conversion tables or take into account circuit anomalies.

I2C not working | PIC18F46K22 + DS Temperature sensor | Microchip

Changing ‘status’ to volatile throws a ” illegal conversion between pointer types” warning. Maybe it’s just too many differences, but any dataxheet would be greatly appreciated!

An analog-to-digital ADC converter with user-selectable precision references this sensor and converts its output to a digital word. Well, I have read the data sheets. I keep it simple by reading just one byte back; this is the whole degrees C value. Also, the Start Conversion command value is different.

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. Nikel Starting Member Total Posts: 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.

If the DS is compatible with I2C signalling it should make interfacing it with a PIC or other microcontroller supporting the protocol pretty trivial.
