pwm to esc converter

it is true there are references in hal and can not be removed.
However, I managed to get the right timing and the motor works.
surely there will be lines that are useless but the important thing that makes the engine run.
thank you

that I know it's impossible
were 3 ms, the rest had to make the PIC12F629

now it works but I can not adjust well to early 1.5 ms.
as I have already fully functional CNC 4 axis servo spindle _ dc 0 -6000 rpm
this configuration has to go only the spindle 30,000 rpm for chisels
in practice it should clean up everything about the spindle in particular
(spindle_9) and put only what you need for this signal.
Now the parameters in the ini file interfere with those hal and I do not understand anything
if you can help me to clean it up you do me a big favor

I read in the integrator manual hostmot2 pwmgen ..
It seems not to have the parameters min-dc max-dc that are in pwmgen software is not it?

Thanks Andy, now I begin to understand something was years since I changed nothing.
I replaced the 7i43 with 5i23 to have more lines for high-speed spindle, extruder for 3d and others.
I upload a picture to show you but I could not ... it's better that you look here:

It definitely something goes wrong only at least 1.5 ms.
without the limit1 ranges from 0.1 ms to about 5 ms

50 150 and I put them at random to try ..
min 50 make 1.5 ms to give stationary spindle
Max has no effect
