Hi all,
I am trying to connect DS2430A with Atmega32 through MMI driver from Maxim (https://www.maximintegrated.com/app-notes/index.mvp/id/4931)- Fig. 6.
As the first test I have connected DS2430A with pull-up resistor to test my One-wire library and everything was OK. I have read family code and serial number correctly. But system presented on Fig. 6 does not work - I checked all connections, transistors and everything is connected correctly (I am using source code developed and tested in the first test) so I can not be sure what is wrong... I have only one change- instead of NDC7001C I am using BS250 and BS170 transistors.
Does anybody have experience with IEEE 1451.4 Class 1?
Thanks in advance and regards.
