  1. EECE6017C Lab 4User Interface with LT24 Display Daughter board Prelab Activities: • Complete the homework given for Lab 3 • Demonstrate the Painter project in the LT24_v.1.0.2_SystemCD folder under “Demonstrations\DE0_Nano_SoC_OCRAM_LT24_Painter” • Go Through the training “Developing Software for the Nios II Processor” from the Training catalog • Download the LT24 sample program for Lab 3 in the course website and try to understand the sample program “LT24_UserInterface” Work to be done during this lab: • Turn in assignments from lab 3 (if you have not completed these, turn them in at the beginning of lab) • Questions on Lab 4 : Discuss the program as given in the Lab 4 sample and come up with questions if there are any • With your team partners, discuss how to design a UI for Traffic Light controller project using the LT24 daughter board. Come up with one description of the UI design and turn in your (joint) solution before you leave lab tonight • Demonstrate how to implement UI (tonight or during lab hours) • Revise team member assignments (if necessary).

  2. EECE6017 Lab 4User Interface with LT24 Display Daughter board • Connect LT24 display daughter board in GPIO 0 port (JP1) in the DE0-Nano-SoC board. • Demonstrate the Painter program in the DE0-Nano-SoC in the beginning of the lab Traffic light problem in MLK and Woodside Dr Intersection MLK • Refer to Lab 2 for the traffic light controller specification • The UI Design should show traffic lights (Green, Amber and Red), Left turn and Pedestrian signals in the appropriate manner according to the timing constraints specified for the MLK and Woodside Dr intersection • Graphics library and GUI samples have been included in the sample folder. • Try to use the SOPC that you have built as part of LT24_Painter demo. • The picture is just a representation of the intersection. You may design a UI of your own. P1 Woodside Dr P2

  3. LT24 UserInterface Application • Download the LT24_sample from the course website. It has the LT24 demo programs for DE0-Nano-Soc with a additional application project added to the LT24_painter_bsp. • Use Eclipse IDE for building the NIOS II projects. The tool is already part of Quartus II software.( check the install directory - altera_lite\16.0\nios2eds\bin). Launch eclipsec-nios2.exe and select the workspace location. • To open an existing project, change the workspace location. For Example, to open the LT24 Painter, LT24_UserInterface and LT24_painter_BSP, provide the workspace location for the demo program - LT24_sample\Demonstrations\DE0_Nano_SoC_OCRAM_LT24_Display. • As an extension of the demo program, one more application project named, LT24_UserInterface has been added to the LT24_Painter_bsp. • Run the application LT24_UserInterface from Eclipse and understand the usage of graphic functions. • Now, Design your own User Interface for the traffic light controller that was designed in Lab 2 and show the traffic light controller output in the display instead of using the LEDs.

  4. Help • To run the Application LT24_UserInterface, Right Click -> Run As-> Run Configurations • Under the Project tab, pull down the drop down menu – Project name, you may select one of the applications and Click Run. • Make sure to connect the board to the computer. DE0_Nano_SoC_golden_top.sof is already programmed into the board. If it is not, you may use Quartus II prime programmer from Eclipse Menu-> Nios II -> Quartus II prime programmer to send the .sof to the FPGA

  5. Homework: • Study Introduction to ARM processors, Building Software based on ARM processor and Build Tools • Go through example My First HPS and be ready to demonstrate the my_first_hps during the next lab
