DS1631 and BS2p24

Jan Dvorak

I would like to try how to use I2C. So, I bought I2C thermometer DS1631 (http://www.chipcatalog.com/Maxim/DS1631.htm). But I wasn't able to use it according to datasheet. I found your application (http://www.parallax.com/dl/docs/prod/boards/28137.pdf) with DS1621 (http://www.chipcatalog.com/Maxim/DS1621.htm). I tried it, but without avail. Could you help me, how to write a correct program for READING temperature?

Jan,

I don't know if this helps since it's for a DS1624...
But if your chip has a "Continuous_Conversion" option, you need to set it first...
Then send the Start Conversion command...

Note that BS2p24 does have the IC2IN/OUT commands so you don't really have to use the low level I2C as I do for the BS2.
You can download the StampWorks manual (that's where I got the original I2C code) and have a look at another I2C example...

Experience level:
[noparse][[/noparse] ] Let's connect the motor to pin 1, it's a 6V motor so it should be fine.
[noparse][[/noparse] ] OK, I got my resistors hooked up with the LEDs.
[noparse][[/noparse]X] I got the Motor hooked up with the H-bridge and the 555 is supplying the PWM.

Also, which I/O lines are you using?· The I²C commands on the BS2p Stamp Modules only work on specific pins.

Chris: yes, I know, I use I/O lines 0 and 1.
Bamse: Thank you very much, but it didnt help me :-( I would need somethink for DS1621 (similar) or DS1631
