HPS Qsys Tutorial

Hi, in case you still require assistance, I'd also recommend this video, I found it pleasant to watch and informative:

If you want to use the HEX displays rather then the LED, you'll need to make a few adjustments:

1. Add a number of PIO's in QSYS, corresponding to the number of HEX displays you wish to use

2. Set the data width of each PIO to 7

3. Export the external connections of your HEX components

4. In the design files, signals and outputs associated with the PIO's should be declared accordingly (for example std_logic_vector(6 downto 0)' if you're using VHDL)

5. Adjust the C code accordingly by declaring pointers to your HEX PIO's and using the right offsets (remember you have 7-bit registers)

Lastly, a few pieces of advice, to avoid some errors (which I experienced):

- You can only execute the TCL scripts after running Analysis and Synthesis

- Use tab characters for indentation in the Makefile
