Minimum value of the timeout_ticks parameter

This question pertains to the app_timer library.

Hi,

I am using the app_timer library for creating/starting timeouts.I had a question about the APP_TIMER_MIN_TIMEOUT_TICKS parameter defined in the app_timer.h fie. My question is why is this parameter defined as 5. Can it be defined as 1? or 2? If so, what would happen if it was defined as a lower number? Timing issues? 

The reason I ask is if I use a prescaler of 255, the minimum timeout length that I can request is then around 35 ms. Unless I choose a lower prescaler, I cannot request a lower timeout length, because the minimum tics it can support is 5 and each tic is 7812.5 us when the prescaler is 255.

Hi Superpak, 

I have forwarded your question to our R&D. I will get back when there is any update. I agree with you that the minimum timeout of 35ms is too large and can possibly be shorter.

Thanks Hung Bui. I will be waiting for your response!
