STEVAL-PCC009V1, universal USB to serial communication
interface (UUSCI) based on the STM32x
Introduction
This user manual explains the functions of the STM32-based universal USB to serial
communication interface (UUSCI).
The objective of this manual is to demonstrate the functions present in the UUSCI
demonstration board and how they can be utilized.
The UUSCI is a tool which has a 10-pin interface. In this interface, there is a provision for
connecting a device which can communicate using I2C, SPI and UART. Therefore the
UUSCI tool allows the user to connect a serial communication-based device to the PC.
While at the same time it allows the user to control some GPIOs available in the 10-pin
interface and set them in input/output modes as per application requirements.
In the UUSCI demonstration board, the STM32 microcontroller is used as the interface
between the PC and the end device. Due to intelligence available in the STM32 device, I2C,
SPI and UART are multiplexed in the same 10-pin interface, leading to reduced board size
and allowing more complex use.
Power to the board is provided from a USB mini B-type connector.
The DLL files of the PC graphical user interface (GUI) are provided with this tool and the
user can use these files to construct their own customized PC GUI as per requirements.
Therefore, the UUSCI tool provides an option for the end user to focus solely on its
application development, as the complexity of the microcontroller is taken care of by the tool
itself, therefore increasing its efficiency and time to market.
The UUSCI tool supports two PC GUIs
■
Universal dongle PC GUI: this PC GUI allows the interfacing of the SPI, I2C and UART
interface and the controlling of the communication parameters with the help of the GUI
itself.
■
DFU mode PC GUI: this PC GUI allows the changing of the firmware if required by the
user to suit its applications. All the other pins in the UUSCI demonstration board are
available in the forms of jumpers, which can be programmed by changing the firmware in
DFU mode.
Therefore, the UUSCI is a complete tool that rapidly allows the prototyping development of
applications.

GPIO settings
Before making the connection to the J2, check the proper settings of the GPIOs which are to
be used along with the I2C interface. These may be control lines chip select or status line,
such as interrupt line. Therefore, you must accordingly set the GPIOs only in this way.
This can be done be clicking the I2C pin interface, as shown in Figure 16.
Figure 16. I2C-pin interface in PC GUI

By selecting the option in the GPIO setting window, you can set the GPIO in different
modes, such as simple input mode, input with interrupt, or push-pull output mode. Also in
the I2C interface, there is an option in GPIO5 and GPIO6 to use these GPIOs as the PWM
clock signal.
If you select the GPIO in normal input mode, the GPIO1 window opens, as in Figure 17. If
you click the “Read” button, you see the GPIO 1 value as '0' or '1'.

I2C header settings
Once you have completed the GPIO settings, you can connect the daughter board to the
UUSCI demonstration board, assuming that the correct settings of the daughter board
control and status lines have been made. Before using the I2C communication, some
parameters must firstly be defined, as shown in Figure 22.
Figure 22. Setting of I2C parameters
!-V
These parameters include the selection of the I2C address types (7 bit or 10 bit), the I2C
slave device address, and the I2C speed.
Once the selection is made, click the “Write” button. This sets the I2C interface and now the
system is ready to read or write the data from the I2C slave device connected to the UUSCI
demonstration board. As soon as this is done, the control settings part freezes and the
“Write” button becomes the “Reset” button, the purpose of which is to reset the I2C settings.
The “Read” and “Write” window opens, as shown in Figure 23.

Depending on the slave device, you can select the register address length (from 0 to 4
bytes, 0 byte length is used for random read and write operation), and then fill the values
accordingly to read and write from the slave device. After every read or write operation, the
GUI updates the status in the status section (e.g. status: communication complete/bus free)
so that you can check the status of I2C communication taking place between the UUSCI
demonstration board and the I2C slave daughter board.
Therefore, this interface allows the connection and testing of any I2C interface-based slave
device.
2.2
Using the SPI interface
To connect the SPI interface please follow the steps mentioned in Section 2.2 and then
instead of the I2C interface, select the SPI interface. The window that opens is shown in
Figure 24.

SPI header settings
Once you have completed the GPIO settings, the daughter board can be connected to the
UUSCI demonstration board, assuming that the correct settings of the daughter board
control and status lines have been made. Before it’s possible to use SPI communication,
some parameters must firstly be defined, as shown in Figure 27.
Figure 27. Setting of SPI parameters

These parameters include the selection of CPHA, CPOL, and baud rate prescaler selection.
(by default, the most significant bit is put first). Once the selection is made, click the “Write”
button. This sets the SPI interface and now the system is ready to read or write the data
from the SPI interface-based daughter board connected to the UUSCI demonstration board.
As soon as this is done, the control settings part freezes and the “Write” button becomes the
“Reset” button, the purpose of which is to reset the SPI settings.
The “Read” and “Write” window opens, as shown in Figure 28.

Using the UART (SCI) interface
To connect the UART (SCI) interface, firstly select “Asynchronous” from the operation menu,
as shown in Figure 29.
Figure 29. Selection of asynchronous interface
AM04421v1
Once the asynchronous interface is selected, an additional menu for asynchronous interface
opens in the GUI, which allows the selection of the SCI or UART interface, as shown in
Figure 30.
Figure 30. Selection of the SCI (UART) interface
AM04422v1
If you click the SCI interface option a window for SCI interface control opens, as shown in
Figure 31.

AM04423v1
Now the PC GUI is ready to be used for testing SCI-based devices. To use any SCI-based
slave device the connection for the J2 jumper must be set, as shown in Figure 32.

2.3.1
GPIO settings
Before making the connection to the J2, check the proper settings of the GPIOs which are to
be used along with the SCI interface. These may be control lines chip select or status line,
such as interrupt line. Therefore, you must accordingly set the GPIOs only in this way.
This can be done be clicking the SCI-pin interface, as shown in Figure 33.
Figure 33. SCI-pin interface in the PC GUI
!-V
Please follow the instructions given in Section 2.1.1 for checking the GPIO settings. Please
note that in this case, only GPIO 3 and GPIO 4 have the PWM clock generation capability.

SCI header settings
Once you have completed the GPIO settings, you can connect the daughter board to the
UUSCI demonstration board, assuming that the correct settings of the daughter board
control and status lines have been made. To impose the settings for the SCI interface, click
on the “Port Setting” button, as shown in Figure 34.
Figure 34. Setting of SCI parameters
!-V
There is another window open in port settings, which includes parameters like the bit rate,
parity bits, stop bits and hardware flow control required, as shown in Figure 35.
Figure 35. Port setting window
!-V
Once the selection is made, the “Set” button must be clicked. As soon as this is done and
you exit from the port settings window, the control settings part freezes and the “Port
Setting” button becomes the “Reset” button, the purpose of which is to reset the SCI
settings.
The “Read” and “Write” window opens, as shown in Figure 36.

Depending on the slave device, you can select the register address length (from 0 to 4
bytes, 0 byte length is used for random read and write operation), and then fill the values to
read and write from the slave device. After every read or write operation, the GUI updates
the status in the status section (e.g. status: communication complete/bus free) so that you
can check the status of SCI communication taking place between the UUSCI demonstration
board and the SCI slave daughter board.
Therefore, this interface allows the connection of any SCI interface-based slave device.

Working in DFU mode
To work in DFU mode, please short pin 9 and 11 of J4 by connecting the 2-pin jumper
mounted on J4. Then, press the reset button on the board.
DFU Setup is available for download at the ST.com website.
Scroll down to software-PC\DFUSE on the webpage and download the zip folder.
The folder includes the setup. After installing the setup, you can plug-in the board. When the
PC asks for the driver, browse to the path of the driver. The driver is available in the installed
software path in the PC at Program Files\STMicroclectronics\DFUSe\Driver.
The user manual for the DFU GUI is also available in the same link.
As a result, you should find the demonstration board enumerated as device firmware
upgrade and it appears as “device firmware upgrade” in the device manager window, as
shown in Figure 37. If this message does not appear, please contact technical support.
