Mustang Streamer is a personal project that runs Volumio3 installed on a Raspberry CM4 with HiFiBerry sound card, 11.9" touch display, led pushbutton (changing color based on audio sample rate) and POE powered. Only two cables: Ethernet and Optical output.

This software works on Raspberry CM4, Raspberry Pi 3, Raspberry Pi 4. Feel free to test on other platforms and please report the issues.

• Turn off display after desired idle time
• Wake up display automatically when player resume
• Led changing color with different sample-rates
• Wake up with button
• Play/pause with button short press
• Power off or reboot CM4 with button long press

• Waveshare POE IO Board for Raspberry CM4
• Raspberry CM4 8Gb emmc
• Waveshare 11.9 inch touch display
• Pushbutton with RGB led
• 3x 120Ohm 1/4W resistors
• 1x 1k 1/4W resistor
• 1x 10k 1/4W resistor
• Raspberry compatible soundcard (in this project is DIGI2 Pro by HiFiBerry)
• Adapter cables (based on your enclosure)
• Some spare GPIO Jumper cables
• RCA Panel connector
• 1x RCA Jack
• Shielded audio cable
• Passthrough Ethernet connector
• Cat 5 Ethernet cable (short)
• Shrinking hose
• Hey, obiouvsly, a box!

Waveshare wide touch display is very very nice!

..but making the square hole in the front panel is a nightmare, this display have about 2mm border and a flatcable on one side.. my suggestion: rasps and files (and be patient, self control, yoga, some cigarettes, no swear)!

Used pins:

Please note, the RGB led in the switch is common anode without internal resistor.

Make sure you have enabled SSH access to your volumio installation.

From a terminal, log into your device with ssh volumio@YOURVOLUMIOIP and:

git clone https://github.com/i0466lt/mustang_streamer.git
cd mustang_streamer
./setup.sh

Reboot your device with sudo reboot

Install Now playing and Touch display plugin from Volumio3 plugin menu

• Under installed plugins, set Screensaver timeout to 0 in Touch Display Configuration

• Make your favourite layout by editing parameters in Now Playing Configuration

• If you want, you can set Mustang Streamer background for idle screen by selecting mustang1_1480x320.jpg under Now Playing Configuration -> Idle Screen

Add these lines to your /boot/userconfig.txt to set your Waveshare display. (Also enables USB for touchscreen)

# Enable USB on Waveshare POE IO Board
dtoverlay=dwc2,dr_mode=host


#### Config for waveshare 11.9" HDMI touch display
hdmi_force_hotplug=1
max_framebuffer_height=1480
hdmi_group=2
hdmi_mode=87
hdmi_timings=320 0 80 16 32 1480 0 16 4 12 0 0 0 60 0 42000000 3
## Display rotation
display_rotate=3 #1: 90; 2: 180; 3: 270

This file contains the pin number assignments and display timeout (in seconds).

Change settings based on your needs.

Login into Volumio device via SSH, enter the mustang_control directory and issue ./update.sh

You can change the PIN Number in config.ini file.

Make sure the desired GPIO Pins are unused. You can check by running gpio readall from terminal.

If you don't have the gpio command install WiringPi unofficial fork at https://github.com/WiringPi/WiringPi. I suggest to install the unofficial fork because WiringPi development ceased some years ago. The unofficial fork works and grant support to new hardware like CM4.

If you are running a Raspberry CM4, make sure you are running gpio version >=2.70 otherwise the CM4 GPIO is not recognized by gpio readall command. You can check your version by type gpio -v in the volumio device terminal.

Example fom my device:

gpio version: 2.70

Yes, I love Deftones! The horse on the logo comes from the album white pony. I've used as part of this useless/non-commercial/diy/free project. (Chino, if you disagree please drop me a mail!)
