Any NXP SDK API to provide delay in microseconds resolution?

[misterbee]

I wonder if NXP SDK for LPC5411X provides any HAL API to introduce delay in microseconds resolutions?

There is common API: SDK_DelayAtLeastUs(), it might not be accurate,but the resolution is us.

HI misterbee 

SDK doesn't have such an API

We suggest using timer to get a accurate delay.

Thanks,

Thank you but how timer can be used as delay?

I am talking about delay that needed in between e.g. I2C command. I don't think timer is relevant.

Enable HW timer first, then poll timer counter value until the delay time is met.
