   * The VGA port displays feedback from the onboard microphone, temperature sensors, accelerometer, RGB LEDs, and USB Mouse.   * The VGA port displays feedback from the onboard microphone, temperature sensors, accelerometer, RGB LEDs, and USB Mouse.
   * Connecting a mouse to the USB-HID Mouse port will allow the pointer on the VGA display to be controlled. Note that some Microsoft mice have difficulty communicating with this demo.   * Connecting a mouse to the USB-HID Mouse port will allow the pointer on the VGA display to be controlled.

-  * On power-up, the seven-segment display will show the results of an automated test for the onboard CellRAM, accelerometer, and temperature sensor. It will then display a moving snake pattern. Note that the accelerometer test will fail if the board is on an unstable or un-level surface when it is powered on, and the temperature sensor test may fail if the board is in an extreme thermal climate. With these two considerations in mind, if your board is reporting a failure, make note of the error code and contact Digilent support at support@digilentinc.com. +  * On power-up, the seven-segment display will show the results of an automated test for the onboard CellRAM, accelerometer, and temperature sensor.

 All Nexys4 boards are 100% tested during the manufacturing process. If any device on the Nexys4 board fails test or is not responding properly, it is likely that damage occurred during transport or during use. Typical damage includes stressed solder joints and contaminants in switches and buttons resulting in intermittent failures. Stressed solder joints can be repaired by reheating and reflowing solder and contaminants can be cleaned with off-the-shelf electronics cleaning products. If a board fails test within the warranty period, it will be replaced at no cost. Contact Digilent for more details. All Nexys4 boards are 100% tested during the manufacturing process.
