EtherCAT clock period

Louis chou

Hi,

The app.cfg file define "Clock.tickPeriod = 1000;" of ethercat_slave project.

Does it can be down to 50(us)?

If answer is NO, how can I create a Clock function which is 50us period time?

It is not recommended to change the clock period. Entire EtherCAT application is based on this clock and this could create lot of undesired behavior.

I guess you need to have a timer function which will be called every 50 us. You could use dmtimer peripheral to do this.

please see the below given forum post for more details
