ESP8266 DS1920 #26

Hello,

There is an issue with DS1920 on the ESP8266. When wired like: http://www.vr-online.ru/sites/default/files/blog/2015/03/sized_3_ibutton_arduino_jpg_12791.JPG The basic example code works with Arduino leonardo, I GET: ROM = 10 56 25 A3 1 8 0 B1 Chip = DS18S20 Data = 1 34 0 4B 46 FF FF 9 10 7 CRC=7 Temperature = 26.19 Celsius, 79.14 Fahrenheit No more addresses.

But it does not work with ESP8266(nodeMCU 0.9) Arduino1.6.5 with ESP 2.3.0 LIB . I GET: ROM = 10 56 25 A3 1 8 0 B1 Chip = DS18S20 Data = 0 FF FF FF FF FF FF FF FF FF CRC=C9 Temperature = -0.50 Celsius, 31.10 Fahrenheit

Always -0.50. Any Ideas?

Nope, can't help, I don't use the ESP chips. I'm depending on the ESP8266 community to submit pull requests.

@Torteski try my fork. That has pull request #8 applied to this master branch. I had similar issues with an ESP board before applying that patch. Let us know here if it works.
