RTOS/TDA3: GIO driver

Hi,

Please let me know how to receive data with the GIO driver provided in SYS/BIOS.

I am looking at the manual of Bios_User_Guide.pdf in <ti_components\os_tools\ bios_6_46_04_53\docs>. When data is received, after setting the reception buffer with GIO_issue, we take a buffer with GIO_reclaim, checking the timing at which the data was received. However, if I do not know the timing to receive, there is a way to poll only.

On the other hand, there seems to be a mechanism to notify by the function callback specified by the user when the data is received in E 6.1 section of the manual. However, there is a concrete method of specifying the callback function, but it is not described in the manual.

So, Could you let me know how to do it. Are there any sample codes or good documents?

Regards,
Kenshow

kenshow,

It's up to the lower level driver to manage the blocking in the GIO_reclaim.

Hi Todd,

I am looking at McSPI drive on PDK01.07.00.16 for TDA.
In mcspi_loopback of mcsdpi example, please let me know which function is call back function, and how bind it.
I want to customize the callback function.

Hi Todd,

Sorry, I change my question of previous posted.

I want to use call back function in GIO_reclaim().
Could you let me know how to set call back function of GIO_reclaim() if I can set.

Kenshow

Kenshow,

Are you talking about the GIO_AppCallback function that is passed into GIO_submit? If so, you cannot use it in GIO_reclaim. If you are talking about the sync field in the create params that is used in GIO_reclaim please refer to the BIOS User Guide section E5. Note: syncs are generally not polling. For example the default is to use a semaphore. The low level driver posts the semaphore when there is data (for the reclaim on an input buffer) and that wakes up the task calling GIO_reclaim.
