Onewire implementation


#1

I have a question to the onewire bus protocoll and how it is implemented in the emx.

Is there a busy wait polling or do you use interrupts to get the sufficient delay’s.

best regards


#2

what do you mean by “busy wait”? What are you trying to do?


#3

Well I mean, if you take the bus protocoll, you can see if you want to do a reset, you have to wait 480µs with low, and then release the bus.

Now does the implementation wait with a timer, or does it wait for expample with a loop that blocks the program for 480 µs?

best regards


#4

Yes block
