> All nuttx timeout use tick unit, so you need just CONFIG_USEC_PER_TICK to match your precision. > But please note that you have to switch tickless mode to reduce the timer interrupt overhead if the precision is around ~10us or ~100us. @xiaoxiang781216 Thank you for your answer. This is something I’m curious about: Why did NuttX choose this design approach? Since there are use cases requiring both periodic OS Ticks and higher-precision timers, Linux addresses this by using hrtimer to provide high-precision timing while emulating a tick device within hrtimer to maintain periodic OS ticks. -- This is an automated message from the Apache Git Service.
