Hi,
I have a simple question:
How should we select data count in GPIF designer for switching sockets? How is it related to DMA buffer size?
Thanks in advance,
David
It depends on your applicaition. We have provided an example AN75779. In this example we have used 2 sockets on the P port. We have used 2 counters to count the amount of data sampled-in. The count limit is decided based on how much data you want to write into one socket. For this example, the counet limit is set as [{(Buffer size in bytes - 16)/1 (as the GPIF interface is 8 bit)} - 1]. Please go through AN75779 and let us know if you have any question.
