DSP56311EVM Sample Code
The DSP56311EVM kit includes sample software that demonstrates various features of the DSP56311 processor
and the DSP56311EVM board. You will need an audio input source and headphones or amplified speakers to run
some of the sample code. The sample code is located at installed directory\dsp56311evm\sample_code.
The following demonstration source codes are included:
60Hz Demonstration (60hzdemo.asm):
This sample code illustrates many features of the DSP56311EVM product. An external audio signal is first applied into an input of the EVM
board. A 60Hz signal is generated by the DSP . Both the external signal and the 60Hz signal are added producing a digital audio signal with an
apparent 60Hz hum. The resultant signal is then sent to a digital 60Hz notch filter which removes the 60Hz hum.
Audio Pass Through Demonstration (pass.asm):
This sample code passes digital audio signals directly though the DSP without any modifications.
Echo Demonstration (echo.asm):
This sample code allows a user to input an audio signal into the EVM. The audio signal passes through the on-board codec and the digital signal
is then processed through the DSP. During the processing of the signal, a delay is added to the signal to achieve a simple echo.
Flash Memory Demonstration (flash.asm):
This sample code illustrates the use of the on board flash memory. The memory can be used to store
user-bootable code.
Filter Test Demonstration (fltr_tst.asm):
This sample code demonstrates the use of the on-board external memory, analog circuitry, and OnCE
port circuitry of the DSP56311EVM.
Please refer to the actual source code files for more information about the sample code.
