You're over the hard part, getting started.

You may not get a badge, but you will gain knowledge and probably have some fun.

That makes it worthwhile to explore.

Also, there's an introduction to the AXI bus in the Programmable Devices II course.

I watched the video -

[mention:6e1bb77faaad47ee8a9f19511e32c0af:e9ed411860ed4f2ba0265705b8793d05] did a fantastic job of explaining the AXI setup in the video. I finally get it. I definitely see the power of the bus inside the FPGA and implemented in any IP.

Adam mentioned that it's his job to do this-- well, he did a great job! Thank you!

The print is taking almost 3 days to finish (reducing infill was not really an option since we want some rigidity), it is quite a big thing, but I want to print the ball joint in one piece.

It should be finished by tonight...

The biggest risk on failing is when it starts printing the ball joint... cross fingers...

Is there a video of this device in action? I have tried making a ping pong ball shooter before using a DC motor, with almost no success. There seems to be a sweet spot for all these mechanisms that can be quite difficult to locate.

Nice start to your interesting project. Waiting to learn more about your plans.

Cool project....I want one...

RE: Ponq - bringing Pong to life with Pynq

Fred27 — Sun, 12 Jul 2020 13:05:38 GMT

Well, I dropped Adam Taylor an email and despite obviously being busy with so many things he found time out of his weekend to chat to me about this and explore possible sources of the problem over a Zoom call and screen share. We seem to have got to the cause of the problem. I have at least got a direction to head in, if not a perfect solution yet. It turns out that the video stream coming in from the HDMI in isn't quite as perfect as you'd imagine. The stream of pixel data arrives in bursts and there's the occasional gap. This explains why the Test Pattern Generator works fine in both Pynq (via mayplotlib) and HDMI out, but the HDMI in works only when fed into Pynq. Buffering it gives an output that regularly flickers out when the buffer underflows, but I can at least work from there.

Update: I feel I'm getting closer but still can't quite get it to work. I have converted this guide to HDMI to to work with Vivado 2019.1 and can happily generate an 800x600 HDMI output. I have removed my own IP and have the HDMI-to-Pynq design we created in the work shop processing 800x600 HDMI in from a Raspberry Pi. However, I just can't get the video stream from the Color Convert IP displaying on the HDMI out. I know it's OK as Pynq can display it. The only difference I can see is that the Pynq video stream is working at 142MHz and the HDMI out example uses 100MHz, but I've matched this to the AXI4-Stream to Video Out.

Has anyone managed to get HDMI in feeding through to HDMI out on the Pynq Z2? Adam Taylor's said he's happy to respond to emails, but I feel he's probably busy so I might struggle on a bit longer and leave that as a last resort.

A good project. Getting the numbers onto the video stream is good, I couldn't do it. An automatic scoring system is a good idea though, nobody likes to be the scorer.
