OMAPL137 Interrupt library

Other Parts Discussed in Thread: OMAP-L137, OMAP-L138

I want to add interrupt support to my projects (int 11). Should I be looking for a CSL.lib for the C6713? And configurating the cmd file.

Also, help configuring the OMAPL137 Codec for 24 bit A/D. I started with the SD example, however it is 16 bit and sends both channels in a single 32 bit word. I can read 24 bit data, but only one channel. My attempts to read the other channel didn't work.

Thanks

Jim

    Jim,

    Interrupt support using the C6713 CSL library is probably compatible with OMAP-L137, but the event numbers (i.e. 0-127 corresponding to CPU or peripheral events) are different for the new device.  This means you would need to find the correct event numbers in the OMAP-L137 TRM, not in the header files for the CSL library.  You also have some other options for interrupt support:

    1. The system_config library in StarterWare for OMAP-L138 also provides OS-independent interrupt handling.  As above, the event numbers in the standard header file will not match your device, but the library itself should work as-is on OMAP-L137.
    2. DSP/BIOS 5.x provides interrupt support.  This is the easiest solution if your application already uses DSP/BIOS.
    3. SYS/BIOS 6.x (see above)

    You can find more information about StarterWare from this URL:

    For questions about the audio codec, I recommend posting on the audio converters forum:

    Hope this helps.
