View source for Howto setup rpi3 for CSV reading



This howto will cover the steps to setup a Rasperrypi for reading CSV stream from RPICT series board.

=Hardware and OS=
This has been tested using Raspberrypi 3 Model B

Used OS: Raspbian Jessie 2017-01-11-raspbian-jessie.img

If the image from Emoncms is used then this setup is not needed.

=Steps=

==-1-==

Download the image from the raspberrypi website.
https://www.raspberrypi.org/downloads/raspbian/

==-2-==

Write the image to the SD card. Follow instructions given by the raspberrypi website.

https://www.raspberrypi.org/documentation/installation/installing-images/

==-3-==

Once the image written create an empty file called 'ssh' in the boot section of the image.

==-4-==

Power up the raspberrypi and connect it to the ethernet network. <br>
Access the raspberrypi with ssh.<br>

===Linux based OS===
This is as simple as issuing.<br>
 $ ssh pi@raspberrypi

<small>Use password raspberry</small>

===On other systems (windows, ios)===
We recommend to use the putty tool. [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html Download here]<br>
As above use<br>
hostname: raspberrypi<br>
user: pi<br>
password: raspberry<br>

This will give you access to a terminal window in which you can issue commands on the raspberrypi.

==-5-==
Run the raspi-config tool
 $ sudo raspi-config
In the menu expand the Filesystem (optional).
 1 Expand Filesystem

Then disable the login uart
 7 Advanced Options
then go to
 A8 Serial
Select '''No''' to the login shell question

==-6-==
Update the Raspbian OS.
 $ sudo apt-get update
 $ sudo apt-get upgrade

==-7-==
Edit the /boot/config.txt file
 $ sudo nano /boot/config.txt
Change the line 
 enable_uart=0
into
 enable_uart=1

At the end of the file add the following line:
 dtoverlay=pi3-disable-bt
(note the above will disable bluetooth - refer to other documentations if this is not desirable).

Save and Exit file.

==-8-==
Disable hciuart
 $ sudo systemctl disable hciuart

==-9-==
Reboot
 $ sudo reboot
return to the ssh session again once the raspberrypi up and running again.

==-10-==
Insert the RPICT board on the RPI. Configure and read from serial port
 $ stty -F /dev/ttyAMA0 raw speed 38400
 $ cat /dev/ttyAMA0
or
 $ stty -F /dev/ttyS0 raw speed 38400
 $ cat /dev/ttyS0
