Hello
I want to know how to perform gpio isr quickly.
To briefly explain the function I want to implement,
There are 2 gpio pins, one is input and the other is output.
When the input is high, the output is also output high,
And when the input is low, the output is also output low.
So I set an interrupt on the gpio input rising edge and falling edge,
And when the gpio input is high, the output is output high, and when it is low, the output is output low.
The function is performed well, but the problem is the time.
The gap between input and output is currently 8~12us.
I want to reduce it to 80ns.
Is there a way to perform gpio isr quickly?
