Avery Posted April 28, 2017 Share Posted April 28, 2017 HI, We are using "HDMI IN" on the PYNQ-Z1 board to test our HDMI interface. Have two questions. 1. Is there a way to directly toggle HPD signal on the "HDMI IN" port? 2. Is there a program or method for reading CEC signal? Thanks, Avery Link to comment Share on other sites More sharing options...
jpeyron Posted April 28, 2017 Share Posted April 28, 2017 Hi @Avery, I do not have a lot of experience with the HDMI projects I have reached out to the creator of the "HDMI IN" for the Arty-Z7-20. This is the project you are talking about correct? cheers, Jon Link to comment Share on other sites More sharing options...
Avery Posted April 28, 2017 Author Share Posted April 28, 2017 No, it's for the PYNQ-Z1 board. I was directed to this forum by the Digilent Sales team. http://www.pynq.io/board.html Link to comment Share on other sites More sharing options...
jpeyron Posted April 28, 2017 Share Posted April 28, 2017 Hi @Avery, Sorry about the confusion, some of the Arty-Z7-20 projects could work for the PYNQ-Z1. I was looking through the examples on the website for the PYNQ-Z1 and I didn't see a "HDMI-IN". If you are using a project for the PYNQ-Z1 from here then I would suggest to use the forums provided for the PYNQ-Z1 here. Again sorry for the confusion. cheers, Jon Link to comment Share on other sites More sharing options...
sbobrowicz Posted May 2, 2017 Share Posted May 2, 2017 @Avery Here are the answers to your questions: 1) Yes, pin T19 attached to the PL of the Zynq can be used to control the HPD signal. See the HDMI section of the PYNQ-Z1 reference manual for some more info: https://reference.digilentinc.com/reference/programmable-logic/pynq-z1/reference-manual#hdmi 2) Sorry, we don't have any CEC demos.
