Description: The 1.EMIF interface
Extended TMS320F28335DSP memory interface (EMIF) is used to connect with the most peripheral equipment, typical application
Extended memory, such as connecting piece. This interface provides the address lines, data lines and a set of control line. ICETEK-
F28335-A will lead to the expansion of these extended line socket for plate on the expansion of the use of.
2 buzzer by the DSP EQEP1S set to I/O pin output control, the frequency of output this pin on the conversion
A sound output.
The control method is to use the DSP generic timer EQEP1S pin changes state level with certain frequency, transmission
A square wave. For general timer register settings, count values for the required frequency count of 1/2.
The frequency of music (C):
C D E F G A B ^C
1234567 ^1
C: 264, 297, 330352, 396, 440495, 528
Connect the 4 buzzer buzzer: as the current required is small, so the DSP I/O pin directly
Driving mode.
