Mopidy-GPIOcont
This is an extension for Mopidy to control your music via buttons. There are 4 dedicated playlist buttons, when pressed a playlist starts. Volume control is done via a rotary encoder and the LCD screen displays relevant information.
Installation
Install by running:
pip install Mopidy-GPIOcont
Or, if available, install the Debian/Ubuntu package from apt.mopidy.com.
Configuration
Before starting Mopidy, you must add configuration for Mopidy-GPIOcont to your Mopidy configuration file (~./etc/mopidy/mopidy.conf). Note that the list_name are strings and should not be followed by a space.
[gpiocont] enabled = true play_pin = 4 next_pin = 23 prev_pin = 24 vol_a_pin = 17 vol_b_pin = 18 vol_bounce_time = 10 vol_change = 2 list1_pin = 6 list2_pin = 13 list3_pin = 19 list4_pin = 26 list1_name = Awesome Mix Vol.1 list2_name = Awesome Mix Vol.2 list3_name = Heerenhuis UU7 list4_name = Loge, koffie! lcd_enable = true lcd_address = 38 lcd_port = 1
The configuration shown here is also the default configuration. Below is an explanation for each setting (Pins are in BCM mode you can see here what your pin numbers are.).
Since Mopidy-GPIOcont uses the internal pullup resistors of your Raspberry, buttons should be connected as:
[Pin] -> [Button] -> [Ground].
Configuration options
Not all config values have to be set, below is an explanation for each configuration value.
REQUIRED
enabled: If the extension is enabled or not.
list<i>_name: Name of your dedicated playlist (no trailing spaces).
lcd_address: Address of your LCD screen on the I2C bus. Hexadecimal without the leading "0x".
Can be found with sudo i2cdetect -y 1 or sudo i2cdetect -y 0.
This command uses the i2c-tools sudo apt-get install i2c-tools.
OPTIONAL (Else default values are used)
play_pin: Location of your play/pause button.
next_pin and prev_pin : Location of your next and previous button.
vol_a_pin: Location of channel A of your rotary encoder (also sometimes CLK).
vol_b_pin: Location of channel B of your rotary encoder (also sometimes DT).
list<i>_pin: Location of your dedicated playlist buttons.
lcd_enable: If you want to enable your LCD screen.
lcd_port: Port of the I2C bus (0 for RasPi 1 and 1 for Raspi 2/3).
These two settings have to be adjusted to fit your rotary encoder if your volume control is not working well.
vol_bounce_time: Time in milliseconds to wait before another edge is detected on channel A.
vol_change: Change in volume (up/down) per detected edge on channel A.
