HDMI

Official Hardware MKR Family MKR Vidor 4000
21

I just bought an mkr vidor 4000 and test this board.

I tried without success the vidor draw logo. Compiling and televerse are good.

But nothing on the monitor even changing it.

I tried also with DVI - HDMI - Micro HDMI. No outout on the monitor.

I check if all libraries are updated.

So what is wrong ? I suppose that this sketch with is an example, does run.

Thank to help me.

Hi alorbac, please try putting board in bootloader mode by quickly doubletapping the button. Red LED should start pulsing and you should be able to see the Arduino logo. If that does not work for you please follow the instructions here:[Solved] FPGA boot loader recovery - MKRVIDOR4000 - Arduino Forum
If this doesn't work either then either the board has some issues or your monitor does not support 640x480 resolution.

Hi

I tried with an very old monitor and ... it run.

Thank for your help and hope that this board 'll progress in the future months.

Since this thread is about HDMI, I thought I'd ask here.

What version of HDMI is the port on the Vidor 4000? I have one which is meant to turn up in the post today, and I want to be able to drive graphics output when using the FPGA from Verilog using the Quartus Prime IDE from Intel.

I want to do this myself rather than using the already existing library as a learning experience.

Hi Cromulent,

In fact the board has an HDMI connector but the protocol used for now is DVI.
If you want to drive graphics output with your own verilog code, you can see my tutorial here :

Hi guys, although HDMI would be possible we can't legally post sources for that as HDMI is requiring licenses and we don't want to get into it. It's a shame we can't output audio along with video but we have to respect the decision of patent holders to request money for their work.
As Philippe kindly anticipated, as a result we only support DVI and this won't change, unfortunately, at least officially. If for personal use you want HDMI I'm sure you can find a way to expand the IP for that...
