There is device driver in the FFTC example project?

Robert W

Hi,

I learned that FFTC operation needs some drivers to do that. I create an FFTC example project import from pdk_C6670 subdirectory. I also learned that the device driver will use GIO and DEV in SYS/BIOS 6. The curious thing is that I do not see the GIO and DEV instances in FFTC project. FFTC uses packet DMA and some registers for controlling. Is this reason GIO and DEV are not shown in the upper right Outline window? FFTC is an internal device. It does not need GIO and DEV? Please correct me. Thanks.

The FFTC does not need any drivers per-se to be usable You could program it directly by writing to the appropriate registers. However TI provides a 'Low Level Driver' (LLD) to help developers by abstracting the h/w interface.

There is no need for GIO or DEV modules.

Thanks. I want to learn device drivers with EVMC6678. Are there driver examples using GIO and DEV? Or, can you tell me what simple device driver can be made for this EVM?

There are no dependencies between the FFTC and the GIO and DEV modules. You can exercise the FFTC directly or by using the FFTC LLD.

If you are looking for drivers for GIO and DEV modules you need to post that as such so that the request is picked up by the right person who can answer your questions.
