I assume that your motor already has commutation circuitry. In that case, you need to build a 'buck' converter and use a PIC with a hardware PWM port to drive the FET. If the motor has a tachometer output, you will need to drive the high side (using a P-channel FET), because most tachometers are ground-referenced.
no am using a castle brushless speed contol i need to send pulse to the r/c connector to made run the motor like connect to a r/c radio
Hi, JetPr
Long time we didn't hear from you ...
So, do not loose our good ol' habits ...
I understand from your post you have a brushless ESC and you need a servo signal generator to drive it without using a R/C set ???
is it true ??? ...
sooo ...

or simply GOOGLE " Servo driver " ... TONS of answers ( W/ 555, 4011, 324 ... Pics, Atmels, Freescale ... )
and from a computer

Thanks for help
no work PULSOUT PORTB.2,255 i use all number from 0 to 1000 and the speed control no start the motor
Thunderbird 18 from castlecreations
May be simply a look to the user manual ??? ...Quote:

and another look to general R/C signals values ...
From the time you " play " with those toys you should know all that.
NOW ... not a PbP issue at all !!! ... for sure

how i made the picbasic pro to do this
The ESC requires a 50Hz carrier signal between 1 millisecond and 2 milliseconds to operate. 1ms is zero throttle and 2ms is full throttle. You will not need to program the speed controller unless your robot requires a different voltage cutoff, brake disabled, or motor rotation direction
Which is a standard R/C PPM signal. 1-2ms pulse repeated every 20msQuote:
