0 1 are the symbols of a binary digit. A binary digit is on off, happy, sad... ,always binary. The only arithmetic you can do with binary is Boolean. (AND, OR, NOT) -1 0 1 are symbols of a trinary digit. A trinary digit is left center right, off left on off right... always trinary. (I just made up t...

All the data books define the assembly language. Most of the language is common to all chips. There are a lot of PIC books around but I have not looked at any of them. The language will not do much good unless you can use it, so get PICSTART Plus from DigiKey and dive right in. A simulator is includ...

Russ forgot to say that you need to subtract the two sensors and send that to the servo.

PICStart Plus from DigiKey will program 18Fxxx.
At least there is a mention of the file format to use for them in the book.

English Mr. B?
Actually I would dump Basic. PIC assembler is much simpler than Basic once you learn it, and MPLAB will help you with that.

Marc thanks for the post. Why did nature build neurons? Because that is the only way to collect many inputs to one output. That is precisely what HalTrees do. This requires that you forget If-then structures. This hung me up for many years and is why not many can understand. Inputs to a HalTree are ...

Microcontrollers are not good computers. Do not try to make a comprohensive program with one. Use them for simple functions, one for each function and connect them with cables to make your big program.
Use the cheapest, simplest microcontroller you can find.

Are you wanting to run servos? You do not need a radio for that. If you want to run servos from your laptop then you can simply connect your printer port to my SMNode ($21.44) which then runs the servo. If you are interested I can work with you on this.

I suggest you go right ahead and buy Microchip Picstart Plus from Dig-Key, (about 100 bucks) and jump right in. There are about 35 assembly language codes. Each takes one clock tick unless a sequence change is made, requiring two ticks. The asembler is sort of strange but easily understood. There ar...

Brain cycle time may be Time = (inputs-1)*c ; where c is the neuron cycle time. Frequency = 1/Time This is the cycle time of HalTrees. c = 30 microseconds in them. That is where the formula came from. It is true that vision is slow. Ever watch a ball player stand and watch a ball go by. Someone coul...

That is the deep question. Numbers are also codes. With numbers you can compute. With language you must code the language with number before you can compute. Computation is different from description. There are more numbers than words. John is a big man. Let big = 1 and man = 1 John = 2. John differ...

Yes, ratios abound. But these are human ideas. Question is, where does nature put the real number decimal point. Chemical arithmetic is based on addition, holes attract poles. Comparison and direction are given by subtraction. Question is, is there a mechanism in nature that multiplies and divides? ...

Mr B Words have different meanings in different contexts of course. A number is a abstract adjective. All we can see are symbols of numbers. Count the symbols, add one for zero and you have the base of the number digit. Analog voltage numbers do not fit this definition. Base 2 symbols are 0 1. Count...

To all. The computer is a simple linear device that must be stuffed by a programmer. Its algebra is: Decode = fetch ; fetch reads a linear array of registers that are filled by a human. The least brain is equal to two computers programmed by nature, meaning contiuous programming forever. To compare ...

Joe, You can buy dials with generic markings, like 0 to 10 or whatever. To have a dial match your machine is a different problem. You can make the machine match the dial or the dial match the machine. As far as marking your own dials in a pretty way is very difficult. There are machines to do this, ...
