I have Volumio running with a Justboom DAC. I am hoping to add the following:
An LCD display to show the track info:
SunFounder IIC/I2C/TWI I2C LCD1602 Display Module for Arduino and Raspberry Pi
I have added this into the GPIO pins that are still available passed through my DAC and I have it lit up with squares across the screen. I have tried for 2 days solid now to get this working changing configs and reading AndyPi tutorial amonst many others.
i2c detect is seeing the device at 0x27 as expected. I have changed the config file at /etc/LCDd.conf as follows:
ConnectionType = i2c
Finally after rebooting the LCDd seems to be autolaunching:
^Cvolumio@volumio:/usr/sbin$ ps aux | grep LCDd
nobody 591 0.4 0.1 2608 1836 ? S 22:48 0:00 /usr/sbin/LCDd -s 1 -f -c /etc/LCDd.conf
The mpdlcd seems to be launching
volumio@volumio:/usr/sbin$ ps aux | grep mpdlcd
root 587 1.1 0.9 11876 9608 ? S 22:48 0:01 /usr/bin/python /usr/local/bin/mpdlcd --no-syslog
volumio 1070 0.0 0.1 4164 1416 pts/0 S+ 22:51 0:00 grep mpdlcd
but the screen is behaving very strange. It is receiving some form of signal as it is flickering on and off frantically when i start music, but it is just showing the squares and backlight, nothing more.
