High Voltage CFL Circuit

Thank you @xs-nrg

It is just that I would like to try that internal 4mhz feature.

I will read the posted book.

With all the information studied I came out wirh this circuit.

I have to practice the way to program the pic to accomplish the task when it come from overseas.

Okay if you look at the table i posted on previous page you can see that there are programmable pullup's on the B ports.
There are no programmable pullup's on the A ports so it's best to use these as output's in stead of the B ports.

The reason for this is that programmable pullup's can come in handy to use with control buttons otherwise you have to use external resistors which make things more complicated on the breadboard or PCB while you can use the internal build in pullup's.

The problem I had was to keep 6 wires on a row sending their pulses in pairs. One negative and the other positive at the same time.

Counting the PortA in order there is the number four that is used for reset connection.
I will not use this motor backwards for now or any speed up speed down for the moment.
I will be content with just making it spin at least to 1000rpm for now. Later when I get this practiced I will move to the other things that can be done with these programs.

By the way I got the 20mhz crystals already. I have not been able to get the 22pf capacitors.

you can use variables to control the motor very easy.
pressing buttons to control speed and overlap.

also you can add fancy sub routines if a button is pressed for over one second in stead of once the steps get bigger by x10 or 2sec= x100 and this will allow you to create a very nice drive for your project
or you can make it run away by itself in a certain amount of time.
you can do about anything with it and that's what makes it so great
