What is the length of FX3 timer tick in miliseconds ? CyU3PThreadSleep

Hi,

What is the length of FX3 timer tick in miliseconds ? 10ms ? Is this length configurable ? How ?

Is it possible to have, for example 1ms or shorter tick in order to do sleep (CyU3PThreadSleep) for 1ms instead of 10ms ?

What is the accuracy of CyU3PThreadSleep and software timers ? That is, exactly 10ms, 1ms or may happen that actual sleep will be a bit shorter or longer depending on, for example, priorities of threads or any other parameters ?

Thanks.

It is 1ms with a accuracy of 4%. We cannot go below 1ms.

It is possible to change it but the change or its limitation hasn't been tested so I wouldn't recommend changing it.

Please let me know the reason why you would want to change it when you can specify the timing in terms of number of timer ticks for achieving higher values.

Regards,

Anand
