PCA9617ADP-ARD user manual
7 GUI description
A GUI application is available for the three EVK boards from NXP Semiconductors.
The application is common for all three EVKs described in Section 6 , and the following
development boards: PCA9617ADP-ARD and PCA9846PW-ARD.
This section describes the GUI application and how the user can control the
PCA9617ADP-ARD daughterboard from the graphical interface. First, install the GUI
package and software on the PC (Windows 10). For more details, see UM11581 .
Once installation is complete, assure that one of the mentioned three EVKs with
attached PCA9617A-ARD daughterboard is connected to a PC and powered-on. Open
“NXP_GUI(PCA9617A,PCA9846)” GUI application. An interface appears as shown in
Figure 11 :
The GUI application starts with Settings tab (marked with red arrow). The left side of the
window displays Board settings . The section provides the following settings:
• Select EVK: displays the list of EVKs. Selecting a wrong EVK board causes the
connection to fail and a pop-up window with the message:
“Unable to Connect with
EVK”
appears on the screen.
• Select COM port:
displays port selected for the communication. The port is
automatically selected by the system (COM 3 is selected in Figure 11 ).
• Select Board: allows the user to select the correct daughterboard (the application can
support two different boards). In Figure 11 , the selected board is PCA9617A. Selecting
the wrong daughterboard causes the connection to fail and a pop-up window with the
message: “Unable to Connect with Daughter Card” appears on the screen.
Assuming the correct parameters are chosen, clicking the Connect button establishes
the connection with the EVK. In the bottom side of the GUI window, a status bar shows in
real time the status regarding connection between PC and the EVK.
In the right side of the window is the
Device setting section. The following settings are
provided:
• DUT EN: sets the OE status of the DUT, when this parameter is controlled from remote
(J14, jumper in position 1-2). With the Set button the value is written in the internal
register of PCA9617A IC.
• I2C Frequency: displays the I
2
C-bus clock frequency (100 kHz, 400 kHz, and 1 MHz).
With the Set button the value is written in the internal register of PCA9617A IC.
• EEPROM Address Selection: allows the user to select the hardware address of
PCA9617A.
The Set button writes the new values in the internal registers of PCA9617A IC. When
the Set button is pressed, a pop-up window with the message:
“Setting device Set
successfully”
appears on the screen. Click “
OK
” to close the pop-up window.
