Reset Button

Pressing and releasing the Reset button restarts the processor and the FPGA.

Pressing and holding the Reset button until the status LED lights (about five seconds) and then releasing the Reset button restarts the processor and the FPGA and forces the roboRIO 2.0 into safe mode. In safe mode, the roboRIO 2.0 launches only the services necessary for updating configuration and installing software.

When the roboRIO 2.0 is in safe mode, you can communicate with it by using the serial lines on the RS-232 serial port. You must configure your serial-port terminal program with the following settings:
  • 115,200 bits per second
  • Eight data bits
  • No parity
  • One stop bit
  • No flow control

User Button

The User Button produces a logic TRUE when depressed and a logic FALSE when not depressed. The User Button is not debounced in hardware.
