Hi , I have problems with interfacing DS1820 to LPC2368. i can see only "127" on display. Thnks.
can DS1820 run at 3.2V ?
See the Datasheet for the answer to this question!
Now it occurs to you to ask yourself that? After you've written all this code based on the vague assumption that the hardware just might work?
I strongly suggest you reconsider your work flow. HW interface issues should be dealt with before you start designing software.
