It's not that the labeling is wrong. The manual shows the correct location of power and ground, however the board is incorrect. The pinouts on the board for power and ground are swapped and are not compatible with the pinouts of the dallas probe. In order for me to use the board, I have to change an...

I was about to start checking through the oscilloscope and I thought I would just double check that I was getting the voltage across the Dallas 1-wire header on the LK202-25 display. When I checked it, I found that the polarity was reversed from what the manual states. This seemed strange and there ...

I did try the FE C8 02 and got the same reply from the display. The display only has 1 connector to hook a probe up although I figure I could chain other probes together and so I have been only using one probe at a time. What I did was switch to a different probe that I bought. It still gave me the ...

I set up a simple program in C that seems to handle the serial communications properly. Here is the section of the code. while (1) { costate { sprintf(tempstr, "%c%c%c%c%c%c%c%c", 0xfe, 0xc8, 0x01, 0x01, 0x10, 0x00, 0xcc,0x44); printf("Wrote fe c8 01 01 10 00 cc 44\n"); nread = 0...

I have reviewed the 1-wire tutorial posted on the forum and understand the bytes I need to transmit to the display. The...
