3.3.1 USB Port
The USB Port sub-panel sets up the USB communication interface between the PC and the target board.
Control Description
Open Target Open USB communication to the target board and read the board name and micro-
controller firmware version. When communication is established, the name of this
control changes to ‘Close Target’ and Setup, Analysis and Control panel access
becomes available in the menu bar.
Close Target Disconnects the previously established USB connection. On disconnection, this con-
trol changes to ‘Open Target’ and the Setup, Analysis and Control panel access
becomes unavailable in the menu bar. The evaluation software constantly monitors
the USB connection status and automatically disconnects if the target board is turned
off or the USB cable is unplugged.
Board Name Displays the type of target board currently connected.
MCU code version Displays the version number of the microcontroller code on the connected target
board.
Reset Target Sends a software reset command to the target board.
Flash MCU Programs the microcontroller code on the target board using the .thx file found in the
“C:\Program Files\Cirrus Seismic Evaluation” directory. This feature permits repro-
gramming of the microcontroller (without using a hardware programmer) when a new
version of the MCU code becomes available.
