Touchscreen Internet Radio, Raspberry

Make this super easy and cool looking 2.8" touchscreen Internet Radio that can be controlled with PC, Smartphone and basically every machine that has got a browser and an internet connection..

(find the speakers at the back from here ;)

Components list:

-Raspberry Pi, basically any one works from the first gen.

-Adafruit PiTfT touch screen

-Cable between the screen and raspberry.

Case was printed with Printrbot Makers kit.

The dimensions in the picture are in millimeters.

The plan is simple. Make a table top case for the screen and raspberry. I had to make the base of the case 3mm taller than in the plans. I was fooled by the length of the solders under the raspberry.

The 3D model of the case was made with ScetchUp, witch is a free and brilliant software to use.

The project will include the printable file, but if you like and want to support my future projects you can buy the files from HERE. Cost is only 1 dollar and helps me a lot :)

All of my printable files on sale in here!

I used a base of the Volumio image to use. It has got in basics a Web based Ui witch means that if you write your raspberry's IP address on your URL bar it will open a page where you can control the Raspberry.

To make the screen work i had to install the drivers to it and make the screen load up in boot. Then i had to install LXDE environment and finally make the raspberry's own internet browser to open up automatically with the Web Ui open.

Look on the next step to see how it is done.

**NOTE**

The Volumio has to be version 1.41 to make the TFT screen work.

I will not guarantee this working in other versions of Volumio.

See volumio's page.

If you are going to use the Volumio without the TFT screen, just use the latest version available.

To connect to the Raspberry it has to be on internet. Access to it via SSH. Use PuTTy for easy access.

********************************************************************************

Basic username is : root

And password : volumio

1. Burn the Volumio image to your SD card. Find the instructions from the Volumio's site.

2. Remap the partition size. Add a line at a time to the console and answer the "questions" as follows.

<p>sudo fdisk /dev/mmcblk0<br>Command : d
Partition number : 3
Command : n
Select : default
Partition number : 3
Partition start : default
Partition end : default
Command : w</p>sudo reboot

After reboot continue.

sudo resize2fs /dev/root

3.Get the drivers from Adafruit for the screen

sudo apt-get update

curl -SLs https://apt.adafruit.com/add | sudo bash

sudo apt-get install -y adafruit-pitft-helper

Wait the processes to finish and continue.

sudo nano /boot/config.txt

Insert this to the txt file.

[pi1]

device_tree=bcm2708-rpi-b-plus.dtb

[pi2]

device_tree=bcm2709-rpi-2-b.dtb

[all]

dtparam=spi=on

dtparam=i2c1=on

dtparam=i2c_arm=on

dtoverlay=pitft28r,rotate=90,speed=32000000,fps=20

Save the file with Ctrl+O and quit Ctrl+X

sudo reboot

After reboot the screen should be black. If it isn't redo the whole thing.

If the screen is black. continue.

Take the touch screen drivers to use.

write the command.

sudo nano /etc/modules

And add to the last line this.

stmpe-ts

Save and quit.

Last things to the touch screen are these.

sudo mkdir /etc/X11/xorg.conf.d

sudo nano /etc/X11/xorg.conf.d/99-calibration.conf

Write these lines to the screen and save.

Section "InputClass"

Identifier "calibration"

MatchProduct "stmpe-ts"

Option "Calibration" "3800 200 200 3800"

Option "SwapAxes" "1"

EndSection

Now the screen and drivers are installed. Don't worry. There is no picture at the time.

4.Next we will install LXDE environment.

sudo apt-get update

sudo apt-get install -y xserver-xorg xinit xserver-xorg-video-fbdev lxde lxde-common

This one is your "desktop".

5.Install and configure Chromium browser and LXDE

sudo apt-get install chromium x11-xserver-utils unclutter

sudo nano /etc/xdg/lxsession/LXDE/autostart

Insert the following lines to the autostart file. Comment (#) the screen saver line.

#@xscreensaver -no-splash

@xset s off
@xset -dpms


@xset s noblank

@chromium --kiosk --incognito --user-data-dir --disable-touch-editing --enable-touch-events http://volumio.local

If you have a problem with the volumio.local address, change it to your raspberrys IP address.

finally write

sudo reboot

6. Now that everything is in order, Its time to wake up the screen.

Write

FRAMEBUFFER=/dev/fb1 startx

You should now have a picture in your screen.

To make it automatically to boot the screen on power up you will have to make a new file to boot it up.

sudo nano /etc/rc.local

Add these lines just before exit 0 line at the bottom.

sudo modprobe spi-bcm2708

sudo modprobe fbtft_device name=adafruits rotate=90

export FRAMEBUFFER=/dev/fb1

startx

save the file.

Reboot and hope for the best.
