Deliver

What should be delivered?

In this assignment, we will have the same functionality as Assignment 1, but with the motor being controlled by the NIOS (soft processor).

For this, it will be necessary to modify the project created in the tutorial to have at least one more PIO peripheral (which will be responsible for reading the buttons). In addition to adding this new peripheral, in this assignment we will improve our system with:

  • JTAG peripheral must generate an interrupt
  • PIO peripheral that handles the button must generate an interrupt
  • Program memory separated from data memory

Once the JTAG starts generating interrupts, it will no longer be necessary to use the JTAG small driver. Remember to change this in the bsp.

Start by reading the buttons without interruption. Once it is working, use the following sites as a reference to implement interruption in NIOS:
