I'm just getting started with this SHARC board and have spent the morning familiarising myself with the crosscore environment. I have looked at a few example projects for this board, but have found myself getting a little overwhelmed by the amount of literature.
There are several things I would like to do:
-Output array of predefined values on one of the pins
-sample an incoming signal at a user defined rate
-store the samples in memory file
-transfer these files to a PC
I want to ask the kind members of this community, what do I need to configure in order to write this program (to be written in C)? Are there any examples on something similar to this?
more specifically is there an I/O library of functions?
Hi Joel, Could you please explain your application in detail. Also let us know whether your using audio application or GPIO related application? -Output array of predefined values on one of the pins>>Can you please clarify which pin are you referring?Regards,Nishanthi.V
The application is for supplying an arbitrary waveform to a current driver circuit for eddy current non-destructive testing. The received signal will also then be sampled and processed by the ADSP 21489.
I was fairly ambiguous about the output pin, I didn't have a specific one in mind, but I guess it would be one of the DAI pins.
Hi Joel,Could you please share us the below details, so that we can assist you further.1. We understand that you are trying to sample the signal. Could you please clarify which peripherals(i.e, Sport, GPIO, SPI etc..) you are using to sample and receive the signal?2. Please let us know whether you are using CODEC for receiving the signal. 3. Also, confirm whether you are trying to process the audio signal or Data.4. Please confirm which DAI or DPI pin you are using?5. Please explain your requirement related to DSP in detail.Regards,Nishanthi.V
I guess part of the issue is I'm not entirely sure which peripherals I need to use? I need to use the CODEC to process a data line on DAI pin 5.
The received signal will be processed and filtered.
