How To Use Commercial Electronic Speed Controller (ESC) Without Remote Controller And Receiver?

If you have a remote control and a receiver read here.
I consider that you have a micro controller, ESC and brush-less motor.
This is something for testing so I will talk in general, however some ESCs will give you this information in details in their datasheet. I have just used 4 to 5 different type of ESCs.
Keep in mind that some ESCs are programmable but they are not programmed in same ways but if you are going to program them, full throttle means the maximum speed.
Most ESCs they will capture the maximum and minimum signals before they start running. In order to calibrate your ESC with signals you have; do the following.
1) Turning the ESC on
2) Max signal applied
3) Waiting for some time (4 seconds for my case)
4) Minimum speed
This should be done step by step and you should not delay between steps.

Till now I did not tell you what the signal is. The signal is having period equal to 10ms.
Pulse width is 1ms for minimum speed and 2ms for maximum speed. This is going to work for most ESCs.
This is how your pulse should look like

So as you can see that the red line shows the maximum speed and the orange line shows the minimum speed.

As you may noticed the ESC will understand when it is not connected to anywhere since the minimum speed which means no rotation will occur at 1ms pulse width and if you don't have that 1ms then the ESC conclude that there is no signal connection.

I have explain here how you can make a waveform like the one above.
