Handling controls of the BLDC motor

You were able to rotate the BLDC motor by using the microcontroller macro. Then, try to control the

rotation speed, brake, and rotation direction now.

In the sample program, the controls are handled in the infinite loop inside the main function shown in

The rotation speed is determined according to the temperature sensor or input from programmed variables,

and the brake is applied whether SW3 is pressed. The direction of motor rotation is determined according

to the position of SW5. “Figure 4-14 Motor controls flowchart” illustrates how the controls are handled.
