In built delay function

durgasivakrishn — Tue, 19 Feb 2019 02:16:03 GMT

Hi,

I am using MK66FN2M0VLQ18 for my application I need to use milliseconds and microseconds delay in the application I want to use inbuilt delay functions as in STM32F7 (HAL_Delay) I am not interested to use PIT Timers for this purpose can anyone suggest me something. And is there any inbuilt function to have such kind of delay in MK66 SDK.

Looking forward to your reply,

Regards,

Hi Durga,

No, NXP Kinetis SDK hasn't such a function. But I think this is not a big problem. HAL_Delay use Systick to count time. It looks like

__weak void HAL_Delay(__IO uint32_t Delay)
{
  uint32_t tickstart = 0;
  tickstart = HAL_GetTick();
  while((HAL_GetTick() - tickstart) < Delay)
  {
  }
}

You can do it by yourself.

Jing
