Step 7. The EPP FOD tuning is necessary to adjust the Rf (frequency) and Qf (quality factor). The value used

is from a Qi certified EPP transmitter and should be set to the register shown below:

9.5 Reference code with STM32 development boards

9.5.1 Hardware requirements

1. STM32 development board (e.g., STM32 Nucleo-144)

2. STEVAL-WLC38RX

9.5.2 Hardware connections

Step 1. Connect the STWLC38 I

C pins to the master I

C bus.

These signals require pull-up resistors to work properly.

Step 2. Connect a 5 V power supply to STWLC38 VRECT/VOUT.

9.5.3 Software requirements

1. Patch/Configuration data in header (.h) file format

2. STWLC NVM programming reference code

3. STM32CubeIDE
