This example program provides a way to test most of the devices on an Altera®-provided development board. The following are tested:
- Seven-segment display
- D0 to D7 LEDs: The "walking" LED pattern is displayed on these LEDs
- UART test: Tests UART functionality for the UART defined as
- LCD display: Displays a short message on the LCD display
- Memory: Runs memory tests on a user-specified range of memory
- Buttons (SW0 to SW3): Detects button presses in a tight loop and returns any non-zero value
Using This Design Example
To obtain this design example, download a free evaluation version of the Nios® II Embedded Design Suite (EDS). This embedded software example is installed with the Nios II EDS in the <Nios II EDS installation path>/examples/software directory and is available as a Nios II integrated development environment (IDE) project template. The template includes the project settings required to run this design on the supported target hardware configurations. To use this software example, simply create a new C/C++ application project in the IDE and choose the desired project template.
The use of this design is governed by, and subject to, the terms and conditions of the Altera Hardware Reference Design License Agreement.
This example requires the following devices to be present in the target hardware design:
- LED programmable I/O (PIO) named
- Seven-segment display PIO named
- LCD display named
- Button PIO named
- JTAG connection (to test the JTAG UART functionality)
