1 Software installation

The STEVAL-USBI2CFT is based on the FT260Q, USB HID to I2C bus convertor. The FT260Q does not require

any additional software drivers.

The Windows operating system automatically installs the necessary driver after the first USB plug-in.

UM3226 - Rev 1 page 2/17

2 Hardware connection

Before starting the communication with a wireless receiver or transmitter, the dongles shall be correctly connected

to each other. Connect GND of bridge with GND of evaluation board, continue with connecting of SDA, SCL, and

INT.

The STEVAL-USBI2C board includes an internal level-shifter.

The voltage level can be changed soldering one of the soldering bridges.

The voltage can be set to 1.8, 2.5 or 3.3 V depending from what solder bridge was soldered.

Ensure that the target evaluation kit is connected to the USB-I2C bridge and the bridge is connected to the PC

with the STSW-WPSTUDIO software installed.

The STSW-WPSTUDIO can connect a maximum of two USB-I2C converters, allowing PTx and PRx to be

evaluated simultaneously.
