This program gets 7-band frequency data from the MSGEQ7 library and displays a 7-band, 2-row bar graph on an LCD display using custom characters.
Dependencies: MSGEQ7 TextLCD mbed
Note this program uses great LCD custom character code from Lluis Nadal to create the LCD bar graphs: http://mbed.org/users/lnadal/code/Lcd_Custom_Char/
