Timers of less than 1 ms

[feraro]

Hello.

How could obtain Timers less than 1 millisecond and MQX TWR60N512 7.1?.

Thanks

You can use the PIT, programmable interval timer.

Thank you very much for the idea, but I'm new to MQX and can not understand how to use a PIT. What I need is to create a pulse train by pin PORTE PIN10 of 0.1 msec period.

Thanks for everything.

If you want to toggle an output pin that fast, try the FTM, which does PWM.

The Reference Manual for your chip will tell you if port E10 can be connected to some FTM channel. If not, you can toggle a GPIO pin in software from a PIT interrupt, but that incurs jitter.

Hey.

I've definitely got it working with the PIT.

Thank you very much for everything.
