how to keep a delay for write in to accelerometer

[balaji]

Hi,

i am using accelerometer sensor, which is i2c compatible.

i have nrf51822 pca10001 board.

in accelerometer datasheet it is mention as after every write there should be delay of 450 us.

so i kept delay as

void delay() { uint32_t i=0; for(i=0;i<0xffffffff;i++); }

but it is taking too much time.

so i want know , what should should be i value for nearly 460 us delay.

means how many clock cycle it wil take.

i don't want to use timer in this case.

kindly suggest me

You can use the nrf_delay.h library for small delays. For larger delays, I would recommend using a timer instead (for best current consumption)
