Raspi-R app functions
Most functions send Linux commands to the Raspberry Pi via ssh (secure shell). Select the appropriate function from the menu and then:
- select a Raspberry Pi you want to connect to from the drop-down list on top
- Connect (button below)
- select a Category (left drop-down)
- select a Command (right drop-down)
- set Command Options (if applicable)
- hit the Go! button
Long running commands can be --Detached--. The command continues running on the Pi, but you can then use other command. (Detached commands will not display there output to the screen anymore)
You can setup multiple Pi-s. Specify at least a host-name/IP-address, user, password and sudo password (for user pi they are the same).
When using one Pi on different (WiFi) networks, make a new entry for every network (with the appropriate Host-name/IP-address.)
Raspi Device info
A lot of info from the Pi, just look around...
A lot of common user Linux commands...
Raspberry Pi log-files
Show / monitor several Linux log-files with tail (-f).
apt-get package manager
You will know the Raspbian/Debian package manager from sudo apt-get update && sudo apt-get upgrade. Beside the update and (dist-)upgrade commands you can install and remove packages used in conjunction with the Raspi-R app.
I will here specially mention:
- wicd-curses - Wired and Wireless Network Connection Manager
(to get a stable Wifi connection)
- configure networks in a terminal: ~ $ sudo wicd-curses
- Apache2 - web-server
- to view last-taken (with Raspi-R) PiCamera picture in the browser
- PiFace Digital - library install for PiFace
(included in the latest released of Rasbian)
- avconv - convert time-lapse pictures into mp4 video
Set (and read) the 8 input- and output ports.In combination with a PiRack you can control 4 PiFace boards.
Pi Camera (PiCam and PiNoIR)
You need to have a PiCam or PiNoIR (no Infrared filter camera) attached to the Pi.
Take a picture, record a video, start/stop time-lapse photography, view last taken picture, video or TimeLapse (needs apache2 web-server and Raspi-R web-files uploaded to apache)
Execute some python scripts. Before running the scripts you must upload the script-files with the function "Scripts Upload to Raspi".
Scripts Upload to Raspi
Upload python3 scripts to ~/Raspi_R/python3/ directory on the Pi. You can check and view the uploaded scripts.
Edit your own 'my_...py' scripts with your favorite editor on the Pi, and run the scripts with the Raspi-R app.
(in future release)
