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.
Access the raspberrypi with ssh.

Linux based OS

This is as simple as issuing.

$ ssh pi@raspberrypi

Use password raspberry

On other systems (windows, ios)

We recommend to use the putty tool. Download here
As above use
hostname: raspberrypi
user: pi
password: raspberry

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
