HRTIM Dead time feature request

Hi @victagayun​ 

Thank your for your post. We need a step by step scenario to be able to understand your request.

Can you please give us the exact scenario to try reproduce what you are seeing?

Best regards,

Hello,

This is a feature request.

AS show below, you can check immediately the resulting Freq by changing the period numerically.

Hopefully there is a similar info when you change the deadtime Rising/Falling Value, like how long will the deadtime incur.

Hi @victagayun​ 

Could you please share your .ioc file to check with.

Best regards,

Hi @victagayun​ 

Thanks for your post. I have raised your change request internally to be reviewed and treated accordingly to the priority.

Thanks for your contribution!

Hi @victagayun​ 

Could you please provide the formula based on what we have today.

Best regards,

Hello @Nesrine.JLASSI​ ,

If you calculate the resulting PWM freq as shown below

like this formula:

HRTIM_Freq = HAL_RCC_GetHCLKFreq() * pTimeBaseCfg.PrescalerRatio / pTimeBaseCfg.Period

then dead time can be calculated like this:

HRTIM_deadtime(rising/falling) = pDeadTimeCfg.RisingValue / ( HAL_RCC_GetHCLKFreq() * pDeadTimeCfg.Prescaler )

And you can insert inside the RedBox the value as shown below.

Hi @victagayun​ 

This will be internally checked, I'll give you an update as soon as possible.

Best Regards,

Nesrine
