Hi Everyone,
I want one wire communication between 8051 TO Arduino . 8051 act as master and Arduino act as slave. i pressed the button on 8051 send to button like key value to arduino and arduino receive the key value to print button state in serial monitor. I need answer for this question.
I moved your topic to an appropriate forum category @praveen_petal.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
What button? What 8051? What code is running on it? How is it connected to the Arduino?
What Arduino are you using?
AFAIK, Maxim (formerly Dallas; now Analog Devices) have never published any 1-Wire slave implementation or specification - only the Master - so what code are you using on the Arduino? How have you tested it?
Does your 8051 correctly read any standard 1-Wire devices?
As @DrDiettrich noted, there isn't actually any question in your original post.
