---------------
|
|
|
|
The examples in this directory are provided to give the user some idea of how the VDMA
|
|
and its driver are intended to be used.
|
|
|
|
Examples:
|
|
|
|
1. AXI VDMA SELFTEST EXAMPLE:
|
|
|
|
This example does basic reset of the VDMA core.
|
|
|
|
FILES:
|
|
* xaxivdma_example_selftest.c - This file does the basic reset of vdma core.
|
|
|
|
2.AXI VDMA INTERRUPT EXAMPLE:
|
|
|
|
This example demonstrates how to use the AXI Video DMA with other video IPs to do video frame transfers.
|
|
This example does not work by itself. It needs two other Video IPs, one for writing video frames to the
|
|
memory and one for reading video frames from the memory.
|
|
|
|
FILES:
|
|
* xaxivdma_example_intr.c - This file runs interrupt example for data transfer.
|
|
|
|
3.AXI VDMA TRIPLE BUFFER EXAMPLE:
|
|
|
|
This VDMA example demonstrates how to use the VDMA triple buffer API.
|
|
|
|
FILES:
|
|
* vdma_api.c - This file has high level API's to configure and start the VDMA transfer.
|
|
* vdma.c - This file comprises sample application to the usage of VDMA API's in vdma_api.c.
|
|
|
|
NOTE:
|
|
* These examples assumes that the design has VDMA with both MM2S and S2MM path enable.
