If you've just come from the basic circuit page you've probably got a bread board version done. If not do it NOW..... ______________________________________________________________________ 1: The basic circuit is just like a spinal cord without anything attached. You need some sort of clue as to what it is doing so add low power LEDs to the ouput of each Nv like so..... [INLINE] (One NV shown) This makes it possible to see what the hell is going on. You can't drive motors yet but untill you are acustom to the basic stable states of the MicroCore the motors will make even less sense than the LEDs. 2: Power it up using a battery or VERY well regulated supply. [INLINE] This is what you should get. This is know as Saturated state. This means all Nv's firing at Max rate. There is a Maximum of 3 Procesess (A process is defined as one LED/Nv on) at any one time, note that there is never two LEDs that are side by side on at the same time. This is the Fermei exclusion feture of the MicroCore and an atribute shared by biological Nv nets. Saturation is the natural Power-on state. It is sort of the Crazy go nuts stae for a Nv Net. Kind of like a bug that's had too much coffee. Saturation will ocurre when a the MicroCore encounters a disruption in main power or when Too Much data is incurred from sensors or hiarchal Nu/Nv nets. Imagine 50 peole beating you with a baseball bats at once. You'd curl up in a ball and freeze, this is sort of what happens to a Nv walker in saturation. Fortunatly its easy to get a more stable usfull state. 3: Adding a Process Nutralization circuit (PNC). Wire up a switch to short out one of the input bias resitors like this..... [INLINE] Closing this switch destroys any passing process. Hold it long enough and all processes are destroyed. Not really a good thing so.... 4: Two process state. By holding the switch closed for aprox 2 seconds you should be able to acheve this.... [INLINE] If all values are even, and no feedback is available (say from a motor),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 trying to act against each other and if they fall into the 180 degree sinc then you have lock up (ever seen the movie "Awakanings"). This state can be usful in some cases but in the case of a simple walker its not much use. 5: The single process state.... [INLINE] By Holding down the PNC switch for another 3 seconds or so you should get this. This is the stable One Process state that is the basis of most of the Nv walkers. 6: Null state, aka Off, this is a Nv net at rest.. [INLINE] Kind of boring Huh.... 7: Adding a Process Initailize circuit (PIN) [INLINE] By wiring up another switch from an input to Vcc (+ve) you can introduce processes to the MicroCore. So by using th PNC and The PIN you should be able to cycle through all the MicroCore's usable states. 8: Now Play with it, get used to it, Understand it, and then go on to the Wiring Up Some Legs section.
