Description: Simple keyboard player VHDL implementation of the experimental realization of a simple keyboard playing, including automatic and manual performance. Input BTN0 ~ BTN6, 1-7 behalf of seven notes. Alt switchable low pitch, with two DIP switches control: " 00" for the bass, " 10" or " 01" as the alto, " 11" for the treble. A closing move DIP switch/automatic. A switch control memory (memory playback)/not stored. A reset button clr. The output of 8* 8 dot matrix, two digital (display pitch and character), the buzzer. Specific feature: When switched to manual mode, according to the manual button to play music and display. At this point, if the memory switch is set to 1, the currently playing notes are stored, the sampling frequency 10HZ. When the automatic mode switch is set to play stored music system itself. At this point, if the memory switch is set to 1, the manual before playing stored music playback. Ruozai switch back to manual mode, you can connec
