PWM Code using EMIOS for MPC5777C in OPWFM

[dineshmoka]

hi

i am trying to generate PWM signal by using EMIOS module in MPC5777C in OPWFM mode with next period update.The following below i attached my project code. Can u please verify and check where is the problem in my code. I am using MPC5777c-416DS with MPC57xx mother board.

Thank you

hi peter

i updated the PCR[179] value and executed still not getting the output.

Hi,

I tested your code on EVB, with PCR modification and I can see PWM signal on GPIO179 output (PG15 on motherboard). You can also connect PG15 to LED (e.g. P7.1) and see LED toggling.

Hi,

within DD_EMIOS_PWM_init() use 

SIU.PCR[179].R = 0x0600;

to select eMIOS_0 ch0 on GPIO179 pin.
