How to set dead time on BLDC mode?

Hi All,

I know setting dead time through the menu "Advance-Dead time compensation" on FOC mode, but I cound not find any relative menu to set dead time on BLDC mode. 

Could anyone give me a guidance? 

I appreciate

I think global dead time has to be set for each hardware individual when compiling the firmware. For an example have a look at the hw_75_300.h file:

// Override dead time. See the stm32f4 reference manual for calculating this value.

#define HW_DEAD_TIME_NSEC       660.0

When it isn't defined in the hardware file it is set to 360.0.
