Dear Ti members,
I am using DSK 6713. I want to use HPI port for digital output. I want to send data at certain time interval irrespective of the address signal, handshaking signals,interrupt signal. In a word I want to use it as a GPIO as paralel output of digital data at a certain interval, which will be controled by program.
I have gone through the the example loacted at C:\CCStudio_v3.1\examples\dsk6713\rtdx, but did not understand whether it is for HPI port or for something else.
If is for HPI port then I am not understanding how to modify the code for the above memtioned purpose. I am giving the code of that example.
I expect your kind help.
