Built an awesome internet Radio with 2x16 RGB LCD Pi Plate :)

[waltermixxx]

i bought three 256meg raspberry Pi's when they first came out... not sure why, but now I know.... ( i have since purchased 1 512 meg pi ... in any case, with so many of them it would make it easy to dedicate one or two for some real live projects ( and not bread board projects... ) in any case, I digress....

I have a 256 meg raspberry pi in a laser cut case with an RGB Negative 2x16 LCD Pi Plate on it... with a wifi dongle, power, and connected to a Bose Soundock II
i use the buttons on the Pi to turn the radio on, off, and to check current station. I also use left and right to "tune in" one of the internet radio stations ...
it was very easy, based on the LCDtest.py code, and code from Meistervision on youtube who has an awesome 1 hour tutorial on how to build a great internet radio...
i used chron to start up the code below when i turn this pi on

you will have to install the MPD MPC apps... check out Meistervision on youtube: http://www.youtube.com/watch?v=KM4n2OtwGl0


in any case here is my code based on both Thanks Adafruit for a store i would have loved to have as a child... (you kids are spoiled )

Code: Select all

#!/usr/bin/python

from time import sleep
from Adafruit_I2C import Adafruit_I2C

# initialize the LCD plate
# use busnum = 0 for raspi version 1 (256MB) and busnum = 1 for version 2
lcd = Adafruit_CharLCDPlate(busnum = 0)

# clear and initialize purple display
lcd.clear()
lcd.backlight(lcd.VIOLET)
lcd.message("Internet Radio\nStarting")
os.system("mpc stop")
sleep(1)

    # Send some text

    lcd.backlight(lcd.OFF)
sleep(5)

I did want to note that the portion of the code that prints the station and the song title needs work, originally designed to work on a 4x20 lcd.
i was too excited to mess around with getting the text to appear correctly ( Underground 80's new wave... !!!)
this is the bit here:

Code: Select all

f=os.popen("mpc current")
station = ""
for i in f.readlines():
         station += i
# Send some text
lcd.clear()
lcd.backlight(lcd.VIOLET)
lcd.message(station)


if anyone could help with getting it to appear properly on a 16x2 negative rgb backlit display via I2C i would be greatful... i image a some kind of loop that counts to 16 then adds a /n then continues?
any help would be appreciated I'm very new to python and this is my very first attempt and most of this code was borrowed and cobled together
