#52523 Shortest time readable on interrupt

Posted by Julien on 03 September 2013 - 12:54 PM in Netduino Plus 2 (and Netduino Plus 1)

Hi,

Thank you for your answers, this is explain why I get some strange values around 10ms on netduino V1.

 




#52268 Shortest time readable on interrupt

Posted by Julien on 21 August 2013 - 06:16 PM in Netduino Plus 2 (and Netduino Plus 1)

Hi, Considering timers, I try to find what is the shortest time measurable with the netduino. For example, I press a button which starts a timer, and stops on release. Sure for a button, i will read the time precisely. Now if I want to measure response time of something quicker : a relay turn on time (µs). The Linux or Windows scanning time is around 25ms. Here it's different, we have a light embedded OS which is probably faster. What will be the shortest time measurable with IO interrupt ? I mean will I be able to measure precisely 1µs or rather 1ms ?

 

Many thanks

Julien
