　　STEVAL-PCC009V2 IBU Motor Control & IPS universal interface

　　The STEVAL-PCC009V2 board implements an IBU universal interface (IBUUI), which is an STM32x-based USB-to-serial interface bridge consisting of a configurable 10-pin interface and a 30-pin interface.

　　The STM32x microcontroller is used as an interface between the PC and another end system. Various communication peripherals are multiplexed with GPIOs, ADC and PWM channels in both the 10-pin and 30-pin interfaces.

　　With these interfaces, there is a provision to connect a device which can communicate using I2C, SPI and UART. Thus, the IBUUI tool allows users to connect a serial communication-based device to a PC. At the same time, it allows user control of some GPIOs available in 10-pin and 30-pin interfaces, and sets them to input/output mode as per application requirements.

　　IBU马达控制板STEVAL-PCC009V2主要特性:

　　Supports two modes:

　　application mode: the PC GUI allows SPI, I2C and UART interfacing and control of the communication parameters

　　DFU mode: allows the user to change the firmware if required to suit specific applications

　　Board power supplied through a USB Mini B-type connector

　　DLL files provided to allow users to create a customized PC GUI

　　RoHS compliant

　　The IBU UI tool includes the following items:

　　● Hardware content:

　　– One board

　　– BOM list

　　– Schematic

　　● Software content:

　　– DFU firmware

　　– DLL files of the I2C, SPI and UART interface of the 10-pin header

　　– DLL files of the I2C, SPI, and UART1 and UART2 interface of the 30-pin header

　　– Source code (including DFU)

　　● Documentation:

　　– User manual (to work in functional mode)

　　– User manual (to work in DFU mode)

　　– Help file on how to use the DLL file
