Hi Vahid,

Sorry for late reply, I suggest that you'd better debugger the project by IDE software to figure out the exactly problem.

I'm looking forward your reply.

Best regards,

Hi Vahid,

Do you want to a delay function for K20D50? If it's right, you can use LPMR to make it out as below show .

Best regards,

Ping

void LPLD_LPTMR_DelayMs(uint16 period_ms)

{

  if(!period_ms)

    return;

  SIM_SCGC5|=SIM_SCGC5_LPTIMER_MASK;

  LPTMR0_CMR = period_ms;

  LPTMR0_PSR = LPTMR_PSR_PCS(1)|LPTMR_PSR_PBYP_MASK;

  LPTMR0_CSR |= LPTMR_CSR_TEN_MASK;

  while (!(LPTMR0_CSR & LPTMR_CSR_TCF_MASK));

  LPTMR0_CSR &= ~LPTMR_CSR_TEN_MASK;

  return;

}
