I have problem to get a pwm clock.

Hello.

I'm using KW019032EU board

I want to make a 1Mhz pwm clock by using Processor Expert

This is my code.

int main(void)
/*lint -restore Enable MISRA rule (6.3) checking. */
{
  /* Write your local variable definition here */
  /*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
  PE_low_level_init();
  /*** End of Processor Expert internal initialization.                    ***/
  /* Write your code here */
  /* For example: for(;;) { } */
  TPM_DRV_Init(TPM0_IDX,&tpmTmr1_InitConfig0);
  TPM_DRV_PwmStart(TPM0_IDX,&tpmTmr1_ChnConfig0,4);
  /*** Don't write any code pass this line, or it will be deleted during code generation. ***/
  /*** RTOS startup code. Macro PEX_RTOS_START is defined by the RTOS component. DON'T MODIFY THIS CODE!!! ***/
  #ifdef PEX_RTOS_START
    PEX_RTOS_START();                  /* Startup of the selected RTOS. Macro is defined by the RTOS component. */
  #endif
  /*** End of RTOS startup code.  ***/
  /*** Processor Expert end of main routine. DON'T MODIFY THIS CODE!!! ***/
  for(;;){}
  /*** Processor Expert end of main routine. DON'T WRITE CODE BELOW!!! ***/
} /*** End of main routi
ne. DO NOT MODIFY THIS TEXT!!! ***/

But i have problem. when I get the clock, it always have voltage 0 to 0.6v

How can i get a 3.3v clock?

You have to be sure that clock source for the TPM Module is not cero.

What is your clock initialization for TPM Module? Could you show that picture?

Best Regards

I found a way.

I changed a pin channel. I got a 3.3v clock. it is working fine.

Thank you
