Hi,

want to introduce delay function in mpc5777c code, delay in usec. can anyone suggest if there is already any inbuilt delay functionality supported.

Also I am looking for deadtime calculations or sample program of dead time calculations in pwm.

Thanks

Hi Vrushali,

The STM or PIT modules can be used for delay generation.

The eMIOS module channel configured in OPWMCB mode generates PWM signal with inserted deadtime.

See Reference Manual for more info.

BR, Petr

Thanks Petr for your response.

I am using etpu for PWM generation, does it has any functionality to add dead time like emios.

Thanks
