Robotino Raspberry

Introduction

	This page explaines how you can use a Raspberry Pi to upgrade your Robotino v1 and Robotino v2. Upgrading your old Robotino is a dangerous operation. You have to open Robotino and remove the PC104 stack. Then you mount a Raspberry Pi and connect it to Robotino's IO board. If you are unsure how to connect the Raspberry you can damage or destroy the Raspberry and your Robotino. The explanations and pictures that follow are without any warranty and/or support.

Install Raspbian on your Raspberry Pi. Include the Debian Buster repository for Robotino.

apt-get update
apt-get install robotino-daemons

On Robotino v1 and v2 you have to enable the controld2 service.

systemctl enable controld2.service

Edit /boot/cmdline.txt and remove console=....

systemctl stop serial-getty@ttyS0.service
systemctl disable serial-getty@ttyS0.service

Reboot.

The serial line at the Pi GPIO14/15 is TTL level whereas the RS232 connector on Robotino's IO board is RS232 level. The MAX3232 does this job.
