DrDiettrich:
Check your cabling (missing Gnd?). Right Vcc?Ask the library author.
Or get a scope, compare the original and emulated signals, and modify the library until it works as it should.
Hi DrDiettrich,
Thank you for your reply.
I don't there is missing GND is my connection. May I know what Vcc you are referring to?
Will try to get a scope to check.
But I tried using a pulse view program to look at the pulse of the connection between real one wire slave and one wire master. There are some cycle that the reset pulse timing is not constant. May I know is it due to the One Wire master?
Thank you.
Regards,
Nick
