Implement very accurate pulses while using SDK

[yuval]

Hi !

I want to build a distance measure hardware by myself and for this i need to make  some i/o pulses (about 7-8) very accurate in 40Khz. after that, i need to implement a reception process but it is not time critical as the pulses...

The chip (nrf52 must stay connected to a phone)

Is there a away to tell the chip that i need about 200-300Us without any interrupts/events (Also, no Radio interrups),or is there any other way to toggel i/o in 25us for some pulses ?

To generate i/o pulses, you can use the PWM (pulse width modulation) peripheral. As a starting point, you can use the pwm example in the peripheral folder.
