I think a picture page would be of more interest.

I would not use either language on a microcontroller. Assembler is short and easy on all of them, making it easy to learn. You avoid another layer of trouble.

Go to DigiKey and buy yourself a PICSTART which will get you a programmer, assembler and everything you need. Microchip has lots of stuff and you can download everything from their web site.<p>http://www.digikey.com<p>http://www.microchip.com

The frequency is derived from the duty cycle. It is from the cycling of the program that feeds the H-Bridge. The on-off time produces the frequency. It will select itself from the cycle of on- off times. 100% is DC. You cannot do that since there is off time in your program, so 100% may be actually ...

Don't worry about frequency. Think of motor on time percentage. At full speed, motor time on is 100%. At half speed, motor on time is 50% on and so on. At 0 speed motor time on is 0%. Any DC motor is mathematically the same here.<p>The actual time depends on the size of the number you are using for ...

Feed the motor with an integer. Then sign controls direction of run and magnitude is speed to run. Say you have an 8 bit integer. The pulse width is time on and time off. Call them TON and TOFF. TOFF is always off, so it can be replaced with DIR. Call the integer magnitude I. If I is 127 TON is on 1...

Hi Al, I have a set of nodes that emit either a number or 0 depending on condition. These have two inputs I and R. Out = I if I cond R else Out = 0 cond is one of the 16 operators above. Most of them are redundant or useless. So if cond = {=, >, <} this gets lines and ramps in both direction. >= can...

Exclusive OR, XOR is not primative. It is made from two bit conditions. It has to look at two bits.<p>There are 16 multi bit logic operators. They can be numbered and treated like numbers.<p>A B | pair name 0 0 | Z 0 1 | L 1 0 | G 1 1 | E<p>Z L G E 0 0 0 0 Zero (0 bits) 0 0 0 1 AND (1 bit) 0 0 1 0 G...

There are lots of logic operators, but there are only 4 that are single bit. From A and B: A B | E G L Z 0 0 | 0 0 0 1 0 1 | 0 0 1 0 1 0 | 0 1 0 0 1 1 | 1 0 0 0<p>The primative operators are E,G,L and Z E = A = B ;this is an AND G = A > B ;not in current bit logic L = A < B ;not in current bit logic...

VB1 is probably for windows 3.1
Help file format changed from then.
Just guessing.

That is better. Note that all these equations are separate computers. Each equation is a computer. I and R are internal names of the inputs of all nodes. I've been on here so long I thought everyone knew that.<p>AISB = A IS B AWASB = A WAS B AWILLBE = AISB IS AWASB<p>The code for was is:<p>WasNode M...

Is that a yes, no, maybe, don't know, don't care or other answer. I know from the face that it is supposed to be funny. That however is the only indicator.

Let node have I,R as inputs and Out as output. M is an internal variable.<p>IS is Out = I if I = R else Out = 0 WAS is Out = If I = R, M = I, Out = M<p>Truth table M is 0 I R IS WAS 0 0 0 0 0 1 0 0 1 0 0 0 1 1 1 1 0 0 0 1 0 1 0 1 ...<p>Let A and B be events or objects AISB = A is B AWASB = A was B M...

Eddie,
You do not need to know the formula since you have a table, converting ohms to temperature.
I would convert the ohms to volts, use a PIC that has ADC and output the temperature from an internal volts to temperature table.

Zeek, understand that schematic and pcboard layout are different views of the same subject. In order to build from a schematic, you must lay out a board that you can them plug your components into and solder them. Nothing can be made from a schematic except a pc board. You can also use sockets and w...
