DS1821 Help

Hi,

I'm trying to solder a DS1821 chip onto a board and connect it to an ATMega128 for reading temperatures. I'm not too good with reading electrical diagrams and I can't figure out how I should solder the wires etc.

Please can someone have a look at the following link for the layout of the DS1821 and tell me how it should be connected?

I don't understand the part where the resistor needs to be connected to the DQ pin and then it says "Vcc" there.. does this mean that the DQ pin needs to be joined with Vcc (the power) with the resister in between? Please help before I blow the chip

Thanks!

Rick

If you can't make sense of the datasheet, that rather likely means you're not up to the task you've set yourself, and will need help from someone with the appropriate skills.

You should consider working through a textbook on (hobby) electronics before you proceed.

I suspect the only way to avoid damage to that chip, not to mention the other expensive gadgets in the vicinity, would be if you didn't touch a soldering iron in the first place.

I can read a datasheet but not an electrical circuit diagram because I haven't done electronics. I am an experienced programmer who started working on embedded systems just a few months ago so I'm learning :)

I got it working and figured out after struggling a bit. Thanks though,

regards,

Rick

You might try reading "Designing Embedded Hardware" from O'Reilly. A good start for a non-hardware person (like me).
