6.4 Using PCF85263ATL-ARD with another device
The PCF85263ATL-ARD daughterboard can be operated with other EVK board, which
has an Arduino port. There are two options to connect the board: using other EVK
equipped with an Arduino port, and an EVK without Arduino port. In the first case, a
firmware shall be developed according with PCF85263A specifications, and then simply
attach PCF85263ATL-ARD daughterboard to the EVK, to operate the board. In the
second case, using the pin chart of Arduino connectors ( Table 1 ), make the necessary
electrical connections (for power, I
2
C-bus and control lines), and develop the desired
firmware, assuring that is compliant with IC specifications. Use PCF85263A datasheet to
read details about internal registers of the DUT IC and data exchange between internal
controller and the EVK. Assure for correct electrical connections and avoid data conflicts
on the signal lines, to prevent IC damage.
7 GUI description
A GUI application is available for the three EVK boards from NXP Semiconductors.
The application is common for all EVKs and the development boards of the RTC family,
produced by NXP Semiconductors (PCF85063TP, PCF85063A, and PCF85263A).
This section describes the GUI application and how the user can control the
PCF85263ATL-ARD daughterboard from the graphical interface. First, install the GUI
package and software on the PC (Windows 10). For more details, see UM11581 .
