STEVAL-PCC009V1

Universal USB to serial communication interface

demonstration board based on the STM32

Features

– 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

are supplied

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.

DLL files of the PC GUI are provided with this

tool. So a user can use these DLL files to make

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

installed.
