how to set timer delay below 10 ms!?

Hi,

I want to set DA14580's timer delay for 5 ms, so that I can get samples every 5ms. As I have studied DA14580's SDK, the only way to set timer is to use ke_timer_set function which is located in the kernel timer library. However, the time unit for setting timer is 10ms (can't set a timer with 5ms delay) and also there is no way to change this function. I'm wondering how i can set a timer with 5ms delay?

Thanks for your help in advance.

Hi Reza,

Hi Reza,

the documentUM-B-004 DA14580 Peripheral Drivers V1.1.pdfgives more info on the use of timers.

Hi RvA,

Hi RvA,

Yeah I have the same question, but can you explain how we can do for have a microseconds delay function ? I try to do this with the Timer0 but unfortunately I am not able to understand how to set the timer correctly for have a delay function in us.

I configure the timer for 2 Mhz (so 0.5us) and set the "ON" Value timer to 2 with interruption. It doesn't work ...

Any ideas ?

Best regards,

Hi RvA,

Hi RvA,
I found something about how to set timer0 manually using its registers such as TIMER0_CTRL_REG, TIMER0_ON_REG. In order to enable its interrupt I know that I have to use NVIC_EnableIRQ(SWTIM_IRQn), however I don't know where to find its service routine!? Can you help me? Thanks.

HI Reza, yes, you need to

HI Reza, yes, you need to have accepted the SLA for the SDK to access documents with a padlock. Someone will approve that for you in near future.
