Introduction
The IBU universal interface (UI) is a tool which contains:
■
An IBU UI board (STEVAL-PCC009V2), which is an STM32-based USB-to-serial
interface bridge consisting of a configurable 10-pin and 30-pin interface
■
Dll files which are available software resources that allow the user to develop customized
GUIs as per application requirements.
This user manual explains the functions of the IBU UI tool (STEVAL-PCC009V2) and how to
use it. IBU UI is a complete tool to rapidly develop application prototypes. On this
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, various
communication peripherals are multiplexed with GPIOs and ADC and PWM channels in
both a 10-pin and 30-pin interface.
In these interfaces, there is a provision to connect a device which can communicate using
2
I
C, SPI and UART. Therefore, the IBU UI tool allows the user to connect a serial
communication based device to the PC. At the same time it allows the user to control some
GPIOs available in 10-pin and 30-pin interfaces and set them in input/output modes, as per
application requirements.
Power to the board is provided from a USB mini B-type connector.
DLL files are provided with this tool so that the user can make their own customized PC GUI
as per requirements.
Therefore the IBU UI tool, by taking care of all the microcontroller complexities, provides an
option for the end user to focus on its application development, therefore increasing its
efficiency and time to market.
The IBU UI tool supports two modes:
■
Application mode: this PC GUI allows interfacing of the SPI, I
controlling the communication parameters with the help of the GUI itself
■
DFU mode: this mode allows the user to change the firmware, if required, to suit its
applications.
