Hello everyone!

Now I am working with imx6ul processor and I need to use input capture channel.

I found in RM that this have several gpt input capture channels.

Also, I found driver in this forum:

Previously, I worked with microcontrollers like STM32 and etc. And using interrupts was easy.

But here I can not start because I do not understand some.

In this cause I have 2 questinos:

1. How can I use this interrupt in my project for getting data?

2. Can this interrupt capture signal with 1us accuracy?
