qsys project and bonding top hardware module with nios

[Lili_7]

hi every one

i have a question about designing with QSYS in QUARTUS II, which i will appreciate it if any one would help.

so basically i want to have  UI wich take some values from user and process them and then send them to FPGA for further progress. i want to do that with qsys.

so i have now a NIOS and input and output and memory all set up.

now i have a program in c in NIOS II software build tools for Eclipse wich does the ui and some math functions and i have 2 int numbers as outputs. how should i connect this outputs here(basically give this numbers) to my hardware part to use them? 

thanks in advance

Hi,

I am working on this issue. please give me some time

thanx a lot

It's a processor, so you should have the processor write the calculated data (Nios data bus interface) somewhere that can be accessed by other logic in the design, like a memory, either on-chip or off-chip.

Hi,

As we discussed in the call, please follow that steps. I'll make sure to arrange a call on Monday if you have any doubts about that again.

Thank you,

this pic.outline shows precisely what i want to do.

so now i followed steps, in Eclipse i don't know how should i define inputs and outputs(which are nor accessible in de0 nano GPIO, but they are entered by user from keyboard) as you can see in pic.eclipse. and i am facing some errors.

i tried some ways like editing my bsp properties but i Count solve this errors.

best regards

Hi,

please share your platform design or complete project files

Hi,

UART example design project file sharing here. it helps you to read and write data from the host system(user). please try this design. in this project FPGA side UART is used so you need to add extra hardware (TTL to Voltage USB converters like RS232, and Max232) to communicate with your pc only then can you see the exact data. 

you can see FPGA to PC connection block diagram.

thanks Hareesh,

it really helped a lot.
