PMB-PiTFT (Pi MusicBox PiTFT) is small Python program/script/whatever that uses mopidy's mpd-api to show controlling ui on Raspberry Pi's screen.
For more up-to-date version check following forks:
- Arzk/pitft-playerui https://github.com/Arzk/pitft-playerui
- britvic42/pmb-pitft https://github.com/britvic42/pmb-pitft
Shows following details of currently playing track:
- Cover art (From Last.FM)
- Artist, Album and Track title
- Track time total and elapsed
Shows and let user control:
- Repeat
- Random
- Volume
- Playback status
Let user control:
- Screen backlight
Also haves sleep function to turn screen of and stop music after certain time.
- Raspberry pi (I am using model B rev.1)
- Adafruit PiTFT with Resistive Touchscreen ( http://www.adafruit.com/product/1601 )(Bought mine from ModMyPi: https://www.modmypi.com/pi-tft-raspberry-pi-touchscreen )
- Internet connection for Pi
- [Optional] PiBow TFT Raspberry Pi Case ( http://shop.pimoroni.com/products/pitft-pibow ) (Bought mine from ModMyPi: https://www.modmypi.com/pimoroni-pitft-case )
- [Optional] Helvetica Neue Bold-font. You can use normal Helvetica Bold as well or some other font.
- PiTFT touchscreen is not working with Pi2, yet.
- Capacitive PiTFT does not work with Pi1 B rev1. (Model B rev 1 have an older layout for the I2C pins and won't be able to use the touch screen.)
Current installing guide is tested and working with: Resistive PiTFT + Raspberry Pi 1 Model B rev1 + Pi MusicBox v.0.53 . Resistive PiTFT should work fine with all Pi1 B models. I haven't had time and equipment to test capacitive PiTFT yet, but it should work also, except that you need to do small changes to make backlight work (#1).
First you need to install and configure Pi MusicBox(PMB). Instructions and everything else you need for this can be found on their website http://www.pimusicbox.com/ Make sure you enable ssh and set root password.
After installing and configuring PMB its time to take ssh connection to you PMB using ssh and root account. Use your favorite ssh program. I am using putty. After logging in enter following commands:
apt-get install rpi-update echo insecure >> ~/.curlrc REPO_URI=https://github.com/notro/rpi-firmware rpi-update 4815829b3f98e1b9c2648d9643dfe993054923ce reboot
Wait until your PMB is booted and log back in using ssh. Next you will need your favorite file-editor on pi. I use nano.
Open file: /etc/modprobe.d/raspi-blacklist.conf Change line: blacklist spi-bcm2708 To: #blacklist spi-bcm2708 and save the file
Open file: /etc/modules add following lines end of file and save it. spi-bcm2708 fbtft_device stmpe_device gpio_backlight_device
Make file: /etc/modprobe.d/pitft.conf add following lines to that file and save it. options fbtft_device name=pitft rotate=270 frequency=32000000 options stmpe_device cs=1 chip=stmpe610 blocks=gpio,ts irq-pullup irq-gpio=24 irq-base=330 sample-time=4 mod-12b=1 ref-sel=0 adc-freq=2 ave-ctrl=3 touch-det-delay=4 settling=2 fraction-z=7 i-drive=0 options gpio_backlight_device gpio=252
After that editing and creating files its time to give some commands to pi.
apt-get update apt-get install fbi apt-get install python-pygame pip install python-mpd2 apt-get install evtest tslib libts-bin
We need to make symlink for touchscreen.
Open file: /etc/udev/rules.d/95-stmpe.rules
and add following line there and save it.
SUBSYSTEM=="input", ATTRS{name}=="stmpe-ts", ENV{DEVNAME}=="*event*", SYMLINK+="input/touchscreen"
Time to reboot pi one more time. Give command: reboot
Once pi is booted again log back in. Lets verify that your screen is working. Enter following commands and you should see image on your pi's screen. If so everything is ok.

Calibrate touch screen using adafruits tutorial: https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi/touchscreen-install-and-calibrate#manual-calibration
Download pmb-pitft files from github. To be sure to start in the home directory do
cd ~
Then download the following for cloning the git:
apt-get install git-core
After installing clone the git:
git clone https://github.com/ISO-B/pmb-pitft.git
From pitft-ui.py you need to change font if you are using something else than Helvetica Neue Bold and check that path is correct.
To change font edit /root/pmb-pitft/pmb-pitft/pitft_ui.py file line 26 and replace "helvetica-neue-bold.ttf" with your own font name. example "OpenSans-Bold.ttf". You can download Open Sans from www.fontsquirrel.com/fonts/open-sans. Transfer ttf file to /root/pmb-pitft/pmb-pitft/ folder.
This is now daemon and it has three commands: start, restart and stop Use following command to start ui:
sudo python /root/pmb-pitft/pmb-pitft/ui.py start
- Easy option to switch between capasitive and resistive PiTFTs
- Gestures
- Playlist selector
- Got other ideas? Post issue and tell me about it
There is probably better way doing somethings that I have done. It would have been awesome to have this as mopidy extension, but I couldn't find way to pull that out. Since pygame screen things need root account/access. This took lot of trial and error. I have installed pi musicbox again and again counteless time before I managed to audio work with screen.
There might be some bugs left, but don't worry we can fix those, hopefully. Feel free to give any improvement ideas.
