Low power delay

[Sam]

Hi,

I need to wait for a period of 7.5ms whilst my I2C sensor completes a measurement, I am currently using the nrf_delay_ms function however I am looking to optimise the current consumption of my device and the ~5mA current consumption during this period is too high.

What's the best way of me accomplishing this? Shall I initiate a one-shot timer that calls an interrupt routine to retrieve the result after the corresponding time period?

Thanks, Sam

A one=shot timer using interrupts would be as good as any. Or if your I2C device has an interrupt line on it which it can trigger when a measurement is complete, that works too.

Anything except a busy-wait or a timer which requires the HFCLK would do the job, ie use the RTC, not the TIMER
