PCAL6534EV-ARD evaluation board
3. Power-up the EVK board using an USB Type C cable attached to PORT 2
4. Connect the EVK to the PC, using an USB Micro-B cable, attached to J901 debug
port
5. Place SW101 in ON position to power-up the boards
6. Install the MIMXRT1050 target firmware (download UM11581, Arduino shields GUI
and firmware installation manual from NXP site)
7. Install GUI application on the PC (see the instruction file referred in the above step)
8. Open the GUI application to operate the device from the PC. For details regarding
GUI operation see Section 7

6.4 Using PCAL6534EV-ARD with another device
The PCAL6534EV-ARD daughterboard can be operated with an EVK board which has
an Arduino port. There are two options to connect the board: using an EVK equipped
with an Arduino port, and an EVK without an Arduino port. In the first case, a firmware
shall be developed according with PCAL6534EV specifications, and then simply attach
PCAL6534EV-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 PCAL6534 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 entire family of IO
