SAMV71 Xplained Ultra Software Package 1.5

Loader Example

Purpose

The Loader example shows how to detect a specified condition and then execute the embedded applications.

Requirements

This package can be used with SAMV71 Xplained Ultra board or SAME70 Xplained board.

Description

In the demonstration two apps are used, one is "fft_demo", and another is "usb_video". To run the demonstration properly the apps should be flashed into the embedded flash in advance.

The demonstration program detects whether or not an Image sensor is mounted on the board then to execute the UVC (usb_video) example or the FFT example.

For UVC example an image sensor (OV2643/OV5640/OV7740/OV9740) should be used.

Usage

  1. Build the program and download it inside the board. Please refer to the Getting Started with SAM V71/E70 Microcontrollers.pdf
  2. On the computer, open and configure a terminal application (e.g. HyperTerminal on Microsoft Windows) with these settings:
    • 115200 baud rate
    • 8 bits of data
    • No parity
    • 1 stop bit
    • No flow control
  3. Start the application.
  4. The following text should appear (values depend on the board and chip used):
          -- Loader Example xxx --
          -- xxxxxx-xx
          -- Compiled: xxx xx xxxx xx:xx:xx --
    
  5. Execution of the UVC or FFT example.
