| This howto will cover the steps to setup a Rasperrypi for reading CSV stream from RPICT series board. | | This page has been renamed. |
|
| |
|
| =Hardware and OS=
| | See [[Howto_setup_Raspbian_for_serial_read]] |
| 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).

| |
| Change the line
| |
| enable_uart=0
| |
| into
| |
| enable_uart=1
| |
| | |
| At the end of the file add the following line:
| |
| dtoverlay=pi3-disable-bt
