PCF85263ATL-ARD evaluation board
Each evaluation / development board benefits by firmware support which can be
downloaded from the NXP company site (
). Before starting, the EVK
motherboard must be programmed with the corresponding firmware package.
Additionally, a GUI application (Windows 10) is available for download from the NXP
site, allowing rapid testing and operation of PCF85263ATL-ARD daughterboard
through one of the above mentioned EVKs. The GUI application is common for
all three EVKs and for the RTC development board family, manufactured by NXP
(PCF85063TP-ARD, PCF85063AT-ARD and PCF85263ATL-ARD). For details regarding
installation of the EVK firmware and GUI host software on PC please download
EVK_Firmware_And_GUI_Install_Guide_For_Arduino_Boards.pdf instruction file from
). Once the software is installed, the first step is to select the
correct combination EVK – PCF85263ATL-ARD daughterboard, and then the board
can be controlled from the GUI interface. See
and
for more details
regarding the operation of PCF85263ATL-ARD from GUI software.
6 Configuring the hardware
6.1 Using the PCF85263ATL-ARD with an IMXRT1050 EVK board
shows the required hardware for operation of the PCF85263ATL-ARD
daughterboard with IMXRT1050 EVK. The following items are necessary:
•
One IMXRT1050-EVK board
•
One PCF85263ATL-ARD daughterboard
•
One USB-A / USB Micro-B cable
•
A PC with Windows 10 operating system
The IMXRT1050 EVK motherboard can be powered by one of the three methods:
•
Connecting an external 5VDC power supply to the barrel power connector (J2) on the
board
•
Connecting an USB cable from the PC to the Micro-B USB connector (J9) on the board
•
Connecting an USB cable from the PC to the USB connector (J28) on the board. When
the PC is connected in this fashion, the USB port can simultaneously act as a debug
interface. Therefore, by using a single USB cable connected to J28, the EVK can be
powered and at the same time linked to the PC for data exchange.
The older USB ports (from PC) are not able to deliver the necessary current (500 mA),
before establishing the communication, use an external power supply (connected to J2).
From J1 on the EVK board (see ) the user can select the power configuration for the
motherboard. For further details, download the IMXRT1050 EVK Board Hardware User
Guide (MIMXRT1050EVKHUG.pdf) available here (link to be set).
