Round the clock

[camerart]

Normally you won't count to 24 but up to 23:59. But I have missed the point of -/+1 here.

Hi I,

My actual system uses 0 to 3581 steps, but that's complicating things This is why I used the clock analogy. And yes, it is 0 to 23:59, but again this is complicating things, as there are 60 minutes/hour. So I'll use 0 to 11.

The mechanics of my system: A motor moves the pointer to the incoming data, so if it is pointing to 3 and data says 4 then it moves cwise till it matches. The motor moves quickly, so as it comes towards 4 it needs to switch off the motor, before it matches, so I added a deadband, which gives data -1 and +1, where no power to the motor within this band. Now say the pointer is at 3 and data says 5 the pointer is moves cwise and switches the power off at 4. In this example, this looks coarse, but in reality, it is much finer.

I hope this clarifies things.
