Tnx in advance!

you can get the temp.sensor DS1820 for free at maxim-ic.com. I ordered 2 samples, and received them yesterday.

Only need a schematic or so. Offcourse I can use the K145 kit, however I do have most components already. Only problem is: I don't have a PIC programmer. Wondering if there is a schematic without PIC, or where I could buy JUST a preprogrammed pic.

I believe you won't find the programmed pic for sale alone, but you can search for a pic programmer schematic that you can build on a prototype board and use once... maybe you can convince mauri to "sell" you a programmed pic.. the code is available on the author's site..

Thank you a lot, I have just ordered them

Mauri .... what is the syntax for gpasm ..... i have tried eveything but cant get it.

It says define processor ........

could you fill this up please

gpasm ............................

Thanx

you've to specify the PIC used, which you can see as well when just entering gpasm -h

Should be something like
gpasm -p 12c509a file.asm

however, i'm getting only a buch of compiling errors instead of a hex file

**guino** · 04-08-2005, 03:22 PM

I'm sure mauri can just post the HEX file if we ask nicely..

hehe would be nice

anyway, I now got a hex file, gpasm only gives a bunch of errors, so I doubt if the hex file is going to work.

Used command line:
gpasm -p p12c509 -i ds1820.asm

(Needed to copy some .inc files to the bin directory of gputils as well, but at least it compiles or so)

Compiling it for the 16f84 PIC gives me less errors
gpasm -p 16f84 -i ds1820.asm

At least i'm rid of all errors, now only some warnings.
