Part Number: TMS320C6748
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

I am trying trying to configure McASP drivers in the driver table of my project in DEV module in CCS. I need the following details for McASP IOM driver:

1. pointer to IOM_Fxnstable

2. Device specific parameters

3. Driver initialization function

Please advise about the document that can provide this configuration information for McASP driver.

Hi,

The device specific parameters are presented in Section 6.15 Multichannel Audio Serial Port (McASP) in the device Datasheet (www.ti.com/.../tms320c6748.pdf) and in Chapter 23 Multichannel Audio Serial Port (McASP) in the device TRM (www.ti.com/.../spruh79c.pdf)

Driver initialization functions are present in the TI Processor SDK RTOS: www.ti.com/.../processor-sdk-c6748
User guide of the RTOS can be found here: processors.wiki.ti.com/.../Processor_SDK_RTOS_Software_Developer_Guide
McASP driver guide (derived from the link above): processors.wiki.ti.com/.../Processor_SDK_RTOS_MCASP

Best Regards,
Yordan

Hi Yordan,

When I click on the first 2 links in the message above, it does not find the pdf files. (tms320c6748.pdf and spruh79c.pdf).

Also, I am using GIO and not RTOS. Are there any McASP documents for use with GIO?

Please advise.
Thanks

Iqbal

Hi,

I updated the links. They should work now.

Not sure what you mean by GIO, but RTOS is the real time operating system provided by TI (see the link).

NOTE that we support only the software listed here:
www.ti.com/.../toolssoftware
See section Software (5) in the link above.

Best Regards,
Yordan

I was earlier reading SYS/BIOS (TI-RTOS Kernel) v 6.46 User's Guide (June 2016); and Appendix E has a description of GIO Drivers as deprecated I/O module. Does it mean that GIO drivers are not supported at all?

Although I noticed that in CCS ver 5.5.0.00077, there is an option to configure GIO drivers under SYSBIOS -> IO -> GIO.

Anyway, I would like your recommendation, should I be only using TI-RTOS with McASP device for my audio application on C6748 LCDK?

Iqbal
