This is a hardware and software tool that enables TVs and Set-Top-Boxes to be tested in an automated manner.
This is Under development - The features below are goals at this point
Using ATVTT you can :
- Record a testing session using any IR remote control.
- Play back a session to multiple TVs.
- With the addition of some API calls to your app, logs can be recorded and saved to the server.
Install a standard 'rasberrian' debian OS image. The easiest way to do this is via Noobs.
You will want to boot the device and using Settings, enable SSH. You will then be able to connect to the device using a SSH client.
Select the screen/touch technology appropriate for the display you have purchased. I used the 2.8" 'Cupcade'.
$ curl https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/pitft-fbcp.sh >pitft-fbcp.sh
$ sudo bash pitft-fbcp.sh
Select project:
1. PiGRRL 2
2. Pocket PiGRRL
3. PiGRRL Zero
4. Cupcade (horizontal screen)
5. Cupcade (vertical screen)
6. Configure options manually
SELECT 1-6: 5
Device: pitft28-resistive
HDMI framebuffer rotate: 1
TFT MADCTL rotate: 90
Starting installation...
After a reboot the screen should be active and functional on boot.
Edit /etc/xdg/lxsession/LXDE-pi/autostart and add a line to open chromium on localhost.
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
Append this line to the end.
`/usr/lib/chromium-browser/chromium-browser --kiosk --disable-restore-session-state http://localhost`
sudo apt install lirc
sudo /etc/init.d/lircd start
Power up the Pi and SSH into it.
Enter the following in the terminal to download and install LIRC. Answer 'Yes' to any questions when prompted. Note: Do not copy the '$' sign as that denotes the terminal prompt. This is to help differentiate what is a command and what are contents of a file.
$ sudo apt-get install lirc
Next we need to add two lines to '/etc/modules', but first make a backup of the modules file.
$ cd /etc/
$ sudo cp modules modules.bak
Then using your favorite Linux editor of choice (nano, vim, or even emacs), add the follow two lines to the bottom of the /etc/modules file.
lirc_dev
lirc_rpi gpio_in_pin=23 gpio_out_pin=22
We also need to update boot configuration file 'boot/config.txt'. As we did for modules, we should make a back up first.
$ cd /boot
$ sudo cp config.txt config.txt.bak
Then change line 51 of config.txt from
#dtoverlay=lirc-rpi
to
dtoverlay=lirc-rpi,gpio_in_pin=23,gpio_out_pin=22
A fresh install of LIRC does not contain a hardware configuration file so you have to create it. User your editor of choice and create the file '/etc/lirc/hardware.conf' with the following contents:
########################################################
# /etc/lirc/hardware.conf
#
# Arguments which will be used when launching lircd
LIRCD_ARGS="--uinput --listen"
# Don't start lircmd even if there seems to be a good config file
# START_LIRCMD=false
# Don't start irexec, even if a good config file seems to exist.
# START_IREXEC=false
# Try to load appropriate kernel modules
LOAD_MODULES=true
# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="default"
# usually /dev/lirc0 is the correct setting for systems using udev
DEVICE="/dev/lirc0"
MODULES="lirc_rpi"
# Default configuration files for your hardware if any
LIRCD_CONF=""
LIRCMD_CONF=""
########################################################
Next we need to update the '/etc/lirc/lirc_options.conf' file, but as always, make a backup first just incase.
$ cd /etc/lirc
$ sudo cp lirc_options.conf lirc_options.conf.bak
Update line 11 of lirc_options.conf from
driver = devinput
to
driver=default
Reboot the Pi by entering the following. You will lose connection so SSH back in when the Pi is done booting up.
$ sudo shutdown -r now
To test if lirc driver is working
$ sudo /etc/init.d/lircd stop
$ mode2 -d /dev/lirc0
pulse 560
space 1706
pulse 535
to record a custom remote/register a remote device
$ sudo /etc/init.d/lircd stop
$ sudo irrecord -d /dev/lirc0 ~/lircd.conf
Follow the instruction prompted by the above command carefully and at the end at least configure the KEY_POWER. At the end ~/<device-name>.lircd.conf file will be generated
backup the original lircd.conf
$ sudo mv /etc/lirc/lircd.conf /etc/lirc/lircd_original.conf
$ sudo cp ~/<device-name>.lircd.conf /etc/lirc/lircd.conf.d/
$ sudo /etc/init.d/lircd start
you can test if the recorded remote works by
$ irsend SEND_ONCE <device-name> KEY_POWER
$ irsend SEND_ONCE <device-name> KEY_VOLUMEUP
