GPIO programming

brainstorm

Hello,

Is there a gpio library for the orange pi that is similar (in functionality and performance) to PIGPIO  
I am really looking forward to doing a project using the orange PI as it seems to have the good mix of features and performance, but I am not finding much about the GPIO.

Thanks to all for any information, links, etc.

Only ONE port of hardware PWM can use it in OPI.
Moreover the port which can be used is UART0_RX on the on-board (PA5).
This port have the special address.
The function similar to PIGPIO is very difficult.
