Libmraa on ROCK Pi S
This guide describes how to use libmraa on ROCK Pi S.
Install essential packages
Package libmraa-rockpis is in the Radxa APT buster-testing repository. Edit file /etc/apt/sources.list.d/apt-radxa-com.list and add the following:
For Debian Buster
deb http://apt.radxa.com/buster-testing/ buster main
Get the pub key
wget -O - apt.radxa.com/buster-testing/public.key | sudo apt-key add -
Install essential packages:
sudo apt-get update sudo apt-get install -y rockchip-overlay rockpis-dtbo libmraa-rockpis
Enable interface
See ROCK Pi S GPIO pintout. ROCK Pi S has a 26-pin colorful expansion header. Each pin is distinguished by color. mraa define follow:
