Universal USB to serial communication interface
demonstration board based on the STM32
Features
■ Two PC GUIs are supported:
– Universal dongle PC GUI: this PC GUI
allows interfacing SPI, I2C and UART
interface and controlling the communication
parameters with the help of GUI itself
– DFU mode PC GUI: this PC GUI allows
changing the firmware if required by the
user to suit its applications
■ DLL files of the I2C, SPI and UART Interface
are supplied
■ Source code (including DFU)
■ RoHS compliant
STEVAL-PCC009V1
Data brief
STEVAL-PCC009V1
Description
This demonstration board implements an
universal USB to serial communication interface
(UUSCI) based on STM32.
This demoboard has a 10 pin interface. In this
interface, there is a provision to connect a device
which can communicate using I2C, SPI and
UART. Thus UUSCI tool allows a user to connect
a serial communication based device to a PC. At
the same time it allows to control some GPIOs
available in that 10 pin interface and set them in
input/output modes as per the application
requirements.
In UUSCI demonstration board, the STM32
microcontroller is used as the interface between
PC and the end device. Due to intelligence
available in the STM32 device, I2C, SPI and
UART are multiplexed in same 10 pin interface
thus leading to reduced board size and the
complexity of usage.
Power to board is provided from USB Mini B-Type
connector.
their own customized PC GUI as per their
requirements.
Warning: In order to use this
evaluation board
connected to a PC, a
recent version of
Windows
Windows2000
Windows XP
®
, such as
®
or

must be
installed.
DLL files of the PC GUI are provided with this
tool. So a user can use these DLL files to make
