Hi guys,
The thing is I need to measure the time between the moment the ultra-sonic ping is sent and the moment it comes back to measure the distance. I am planning on using a systick timer for that. Of course then smaller the time interval between ticks better the result. But I am not sure about how small should I set the time interval between ticks. Is 1us too small?
Or should I use the MRT and read the TIMER register directly?
I am not sure since normally I only see the example using the interrupts generated by the MRT, never seen anyone read the TIMER register directly.
Regards,
