describes the setup to download firmware/configuration or monitor firmware parameters or
dynamically tune the firmware parameters over the I2C interface of the WLC1150 controller.
I2C communication-based setup
Figure 14
Execute the following procedure to create the setup:
1. Establish an I2C connection between the WLC1150 reference board and the HPI dongle by connecting the
three jumper wires.
Connect a jumper wire between the SCL pin of the HPI dongle (pin no. 5 of the J2 header) and the
a)
HPI_I2C_SCL pin of the WLC1150 reference board (pin no. 4 of the J2 header).
Connect a jumper wire between the SDA pin of the HPI dongle (pin no. 6 of the J2 header) and the
b)
HPI_I2C_SDA pin of the WLC1150 reference board (pin no. 5 of the J2 header).
Connect a jumper wire between the GND pin of the HPI dongle (pin no. 3 of the J2 header) and the GND
c)
pin of the WLC1150 reference board (pin no. 2 of the J2 header).
2. Ensure that a jumper shunt is placed at positions 1 and 2 of the power mode selection jumper (J4) of the Tx
reference board
3. Connect the HPI dongle to the PC using a USB micro-B cable.
4. The Power LED (LED1) on the HPI dongle glows blue.
5. Connect the 65 W USB Type-C power adapter to the Tx reference board using the USB Type-C cable. The
status LED (LED1) on the WLC1150 reference board blinks in blue and red five times.
6. Now the setup is ready for use by the Wireless Charging Configuration Utility.
7. See the Wireless Charging Utility user guide to understand the procedure to monitor firmware parameters,
dynamically tune the firmware parameters, and download firmware/configuration data/monitor and
dubbing. The utility user guide can be accessed from the Help menu of the utility.
8. Dismantle the hardware connection between the HPI dongle, PC, and Tx reference board.
