I've attached a sample schematic from the example folder in sigmastudio which used to control volume and mute. In the schematic, there are 4 RCA inputs, 2 s/pdif inputs and 6 RCA outputs. I've used demo DXE (CCES) for ADSPSC589 given in the example folder of software module.
I have 1 RCA mic as input and 1 RCA speaker as output. Can someone tell me how the processor knows which pins are input and which pins are output? That is, how and where to assign these pins as input and output. I've searched in manual but i couldn't find it.
My second question is, if i want to use just 1 input and output how do i assign it in the code?
New here, kindly help. Thank you.
The default framework is considering, RCA output port is J16 for 8 channels output and RCA input port is J6 for 4 channels input. For any change in channel configuration requires framework modifications. If you want to modify the framework, you need to understand the default framework code flow by running demo application in CCES debug mode. You can put break points in CCES debug mode, so you can understand the code flow.
Thank you for the reply. But, after doing build, for some reason the demo code has 25 errors. Is this common? And this is the only 1 example (CCES codes + Schematic) given by Analog devices for ADSP SC589 . Not sure how to proceed from here.
Could you please share your SigmaStudio Schematic?
could you please share your SigmaStudio schematic?
I hope that you have not made any changes to the Demo application framework.
I'm using 2 schematics to check if i'm getting output on one. And No, I haven't changed anything
in the application framework. Below is the example which is already present in the examples folder. I've just changed hardware configuration from USBi to Aardvark as shown below.
The other schematic is this one below, I've just unchecked the inputs and reduced the mute block and outputs, since I've only 1 input and output source with me.
I'm not getting any output audio on both these schematics.
Please check, whether the same framework API version is selected as shown in image?
Also please check section "184.108.40.206 ADSP-SC589 EZ-BOARD" in quick start guide for hardware switch and jumper settings to setup the target.
Yes, It is same. Also, build configuration in that picture should be build or release?
For big SigmaStudio schematic it should be in release configuration or else it can be debug.
The default schematic have process mode as "Single" and input/output channels as 8 in both the cores IC control window. I am not sure why you have modified and I can't help you until you share your SigmaStudio schematic project.
I've modified it because i have only 1 input and 1 output source (1 mic and 1 speaker) but the demo schematic has 6 inputs and 6 output sources.
Also, how do i share my project? When i try to upload the schematic it throws an error.
Please copy to some folder, zip it and upload.
Thank you for reply. I've uploaded both the schematics as well as the demo code. Kindly check.
I am getting 1 Channel audio I/O with the demo application and schematic you have shared, but the output observed in next RCA output (RCA - Red down the white which we connected before). The DAC output1 connected to RCA red it seems. Please check whether you are getting audio output. If you want to get audio output from RCA white port, you can connect output to CH1 of SHARC0 block processing.
