You may also follow the below steps for any further questions about the lab11e.

1. Please ensure the sequence of the hall input signal is corresponding to the set number in gHall_PwmIndex[].

2. You may increase PWM frequency if possible because the Hall signal is detected in PWM ISR. The delay time will have an impact on the high-speed running if the PWM frequency is too low.

3. Tune gHall2Fast_Spd_Coef, gHall2Fast_Iq_coef, gHall_speed_FastToBldc_low_pu and gHall_speed_BldcToFast_high_pu.

4. Tune the gains of the PI regulator in HALLBLDC_Ctrl_Run().

The motor starts in sensored when gHall_Flag_EnableStartup = true and starts in sensorless when gHall_Flag_EnableStartup = false.

But, the motor is not transitioning from sensored to sensorless when gHall_speed_fdb_pu becomes equal to gHall_speed_BldctoFast_high_pu. The controller is getting reset when it is supposed to transition to sensorless.

gHall_PrevState is reading -2161 when it is supposed to transition and then stops.

Please Help.
