Unfortunately i dont know which IPs i need to include in Qsys. I now additionaly try the Monitor Pro Program of Intel but i think like the HDMI TX Demo showed me something is wrong with my little HDMI Display. But ok this is another topic. important would be .. how to find out the correct IPs for Quartus and how connect them , so that the nios can use the given given example . There is a table of used IPs :Is this the soluton ? Why dont they write how to connect them ?I/O Peripheral Qsys CoreOn-chip memory character buffer Character Buffer for Video DisplaySD Card SD Card InterfaceRed LED parallel port Parallel PortExpansion parallel ports Parallel PortSlider switch parallel port Parallel PortPushbutton parallel port Parallel PortJTAG port JTAG UARTInterval timer Interval timerSystem ID System ID PeripheralAudio port AudioVideo port Pixel Buffer DMA ControllerThank you :D

HI,I presume you already installed "Intel FPGA Monitor Program" where all the example design code is available.For instance, you can use Quartus software to open up DE10-Nano example design where every design blocks are connected nicely for you \University_Program\Computer_Systems\DE10-Nano\DE10-Nano_Computer\verilogWhile the NIOS II C code example design is available in \University_Program\Computer_Systems\sample_programs\nios2\cThanks.Regards,dlim

wow it works. I went down to your given paths and also discovered the directories a little bit by myself. First I tried the FPGA Monitor Program - but it didnt work xD So I opened the .qpf - clicked on the programmer and uploaded the .sof . Then I checked if my FPGA has connection. It had. I saw that the HAL enviromnent is already there . I only had to the main program: video.c and the address maps located in the lib folder University_Program\Computer_Systems\DE10-Nano\DE10-Nano_Computer\software.I compiled it and my HDMI Display showed Intel FPGA Computer System within a blue rectangle.Thank you for your time !Sometimes the solution is close to us and simple :D( i know that this is a prepared environment but anyway it is an important step for me :D)Now i finally can begin to manipulate the output :D

Great ! I am glad thing works out for you

Damn, it turned out that i just had some luck: First time it worked diretly second time i needed to reinstall. Today it even didnt work after reinstall: It just shows some weird random pixels in the first 6 rows . I checked it last time on some "good" displayS and now i am working with a adapter hdmi to vga. So this shouldnt be the reason.I now recompile the project DE10 nano computer. Maybe it has some trouble with the pin allocation ? But I really use de10-nano. So it should be the correct project.If it doesnt work I will post more details :DI could also check the Platform Designers Adresses and the adresses listetd in the .h file for the Nios.Wow it takes now half an hour to compile everything.. Although I made some setting changes for faster compilation etc...😀

Now I created a new project with the Intel FPGA Monitor Program. I configured with the example video.Then ..like always... nothing happens after upload.. then I used eclipse put in again my files (video.c and libs) and it worked. Then I made some change in the String. then a new comination appeared: on top of the screen random pixel appeared and the string also appeared. but I couldn change the string now... needed to download the sof with fpga monitor program again and again needed to put in video.c... now it worked again. but only for 1 time. after changing the string again it hung up or something... now i am trying the third time

Hi i want to use the "Listing 14. An example of code that uses the video-out port" of the document: "DE10-Nano Computer System with Nios® II " It describes how to print out a rectangel with characters onto a HDMI display.

hi , before some weeks I think (!) i found a way to do some hdmi output... but finally my team talked to the hdmi on the hdl level . is there any support for this stuff ? i mean something like a hotline ? because I want to work more with quartus and de10nano - the girl on the phone told me I should use this community ... but answers come really slow :P

Hi,
Good, you got thing working.
I am sorry there is no hotline service for this forum support.
VIP service like "hotline" or "agent on site support" is typically provided by the Intel sales or distributor where customer purchased Intel FPGA product. But also take note that not all Intel distributor is capable to provide luxury technical support service and most the time also depends on business justification.
Take your case for example, I believed you purchased de10nano board from Terasic. right ? Ideally you should be getting technical support from Terasic directly or whoever agent that sold you the product. However if Terasic doesn't has technical support agent then maybe they will direct you to this Intel FPGA forum.
There are Intel support agent (like me) + other users in this forum community to help out each another to try our best to answer the questions in this forum. However since we are supporting multiple forum cases in parallel hence sometime our respond will be slow and I truely apologize for it.
Sorry and I appreciate your understanding on the slowness of respond.

Hi,
I hope I have explained our support challenges to you.
We will try our best to help out on issue cases filed in this forum community.
For now, I am setting this case to closure.
Thanks.
