C6747 interface with ADS7844

Other Parts Discussed in Thread: ADS7844

Hi,

I would like to know where can I get information on how to develop the SPI program to interface my C6747 with TI's ADS7844? I had run a search in this forum on ADS7844 but came up with nothing. If I can get hold of some sample programs will be best, and I can continue my own development from there.

Your help is very much appreciated.

Thanks.

We have a couple of examples for using SPI to interact with devices

1) http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137: Download the source from there and see the Common/drivers/src directory for sample functions on writing to a SPI flash

2) See the SPI Writer program in the PSP for a CCS-based version of the spi flasher. Again, this can give an example of performing reads and writes with the SPI interface.

None of these are specific to the ADS7844 but this along with the ADS7844 datasheet should be able to get you started.
