PIC microcontroller utilizes onboard UART for greater communication accuracy.Track info for Mp3's works fine, but on web radio streams you will get the song title and artist and the stream time but I have not found a way to change the name of the station as they all show as, if anyone knows how to solve this I would be most grateful if they could share the knowledge.SerLCD v2.5 has some new features that make the SerLCD even more powerful and economical: Credit to Andypi for the MPDLCD instructions. Īt start up you should have an lcd screen that will show the track info you are playing. You now need to make mpdlcd start at boot so use this commandĬlose and save the file, now reboot ( sudo reboot). Once you get to the end of the instructions do not reboot, you need to enter a few more commands to get the screen to show what’s playing. Once installed I would recommend connecting via LAN at first boot and from within Volumio's network setting you can set up your Wi-Fi network as required.įollow the instructions as per viewtopic.php?f=35&t=63412 to get LCDproc installed. Texy's screen also works great on Volumio, the updated version of RaspyFi.ĭownload and install Volumio to an SD card, I have used a 2GB one but it is almost full, so I would recommend at least a 4GB card just to allow room for further expansion. tup(LEFT, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set as input (Left button)ĭevice.lcd_puts('abcdefghijklmnopqrst',1)ĭevice.lcd_puts('1234567890abcdefghij',2)ĭevice.lcd_puts('ABCDEFGHIJKLMNOPQRST',3)ĭevice.lcd_puts('Line 4 - Hello !!!!!',4)īreak # quit if SELECT an UP pressed at the same timeĮlif GPIO.input(RIGHT): # if port 21 or 27= 1 tup(RIGHT, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set as input (Right button) tup(DOWN, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set as input (Down button) tup(UP, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set as input (Up button) tup(SELECT, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set as input (Select button) tmode(GPIO.BCM) # set up BCM GPIO numbering
