I am using an Arty-Z7-20 with Vitis 2022.1 installed. I have the HDMI In Demo functioning, and I am wanting to implement a delay on the output HDMI. I cannot find documentation on how to handle the VDMA configuration parameters, or how (or if) the VDMA uses an ISR for memory access.
I am ultimately looking for a parameter that I can set the control a delay in the display output. I have tried editing the following parameter with not much luck as I am hoping to get into the 150ms time frame of delays.
vdma.Config.FrameDelay
With a circular buffer, is there a way I can set how much of that buffer to fill up before I begin the display routine ?
