=== Libmraa on ROCK Pi N10 ===

This guide describes how to use libmraa on ROCK Pi N10.

==== Install essential packages ====

Package libmraa is in the Radxa APT bionic-stable and buster-stable repositories.

Execute the following commands to add Radxa APT

rock@rockpin10:~$ export DISTRO=bionic-testing # for Bionic

or

rock@rockpin10:~$ export DISTRO= buster-testing # for Buster
rock@rockpin10:~$ echo "deb http://apt.radxa.com/$DISTRO/ ${DISTRO%-*} main" | sudo tee -a /etc/apt/sources.list.d/apt-radxa-com.list

Get the pub key

rock@rockpin10:~$ wget -O - apt.radxa.com/buster-testing/public.key | sudo apt-key add -

Install essential packages:

rock@rockpin10:~$ sudo apt-get update
rock@rockpin10:~$ sudo apt-get install -y rockchip-overlay rockpin10-dtbo libmraa # libmraa version: >=0.4
rock@rockpin10:~$ sudo apt-get install -y linux-4.4-rockpin10-latest # ROCK Pi N10 kernel version: >= 4.4.167-14

Install compiler:
rock@rockpin10:~$ sudo apt install -y build-essential

==== Enable interface ====

See ROCK Pi N10 [[rockpiN10/hardware/gpio | GPIO pintout]]. ROCK Pi N10 has a 40-pin colorful expansion header. Each pin is distinguished by color. mraa define is shown below:
