If you've just come from the basiccircuit page you've probably got a bread board version done. If notdo it NOW.....
|1:The basic circuit is just like a spinalcord without anything attached. You need some sort of clue as to what itis doing so add low power LEDs to the output of each Nv like so (resistorshould be at least 3K).....|
(One NV shown)
This makes it possible to see what the hellis going on. You can't drive motors yet but until you are accustom to thebasic stable states of the MicroCore the motors will make even less sensethan the LEDs.
|2: Power it upusing a battery or VERY well regulated supply. |
This is what you should get. This is know as Saturated state. Thismeans all Nv's firing at Max rate. There is a Maximum of 3 Processes (Aprocess is defined as one LED/Nv on) at any one time, note that there isnever two LEDs that are side by side on at the same time. This is the Fermeiexclusion feature of the MicroCore and an attribute shared by biologicalNv nets.
Saturation is the natural Power-on state. It is sort of the Crazygo nuts state for a Nv Net. Kind of like a bug that's had too much coffee.Saturation will ocurr when a the MicroCore encounters a disruption in mainpower or when Too Much data is incurred from sensors or Nu/Nv nets. Imagine50 people beating you with a baseball bats at once. You'd curl up in aball and freeze, this is sort of what happens to a Nv walker in saturation.Fortunately its easy to get a more stable usefull state.
|3: Adding a ProcessNeutralization circuit (PNC). Wire up a switch to short out one of theinput bias resistors like this.....|
Closing this switch destroys any passing process. Hold it long enoughand all processes are destroyed. Not really a good thing so....
|4: Two processstate. By holding the switch closed for aprox 2 seconds you should be ableto achieve this....|
If all values are even, and no feedback is available (say from amotor),then the processes should fall 180deg out of phase with each other. This is seen when they appear to be running side by side with each other.Two processes are sort of like Parkinson's disease the Nv's are tryingto act against each other and if they fall into the 180 degree since thenyou have lock up (ever seen the movie "Awakenings"). This statecan be useful in some cases but in the case of a simple walker its notmuch use.
|5: The singleprocess state....|
By Holding down the PNC switch for another 3 seconds or so you shouldget this. This is the stable One Process state that is the basis of mostof the Nv walkers.
|6: Null state,aka Off, this is a Nv net at rest..|
Kind of boring Huh....
|7: Adding a ProcessInitialize Circuit (PIN)|
By wiring up another switch from an input to Vcc (+ve) you can introduceprocesses to the MicroCore. So by using the PNC and The PIN you shouldbe able to cycle through all the MicroCore's usable states.
