Evaluation board firmware

All source and project files for the microcontroller firmware are included in the Software

directory of the installation CD-ROM.

The evaluation board firmware was developed in the ST Visual Develop rev. 3.3.2 IDE with

16k limited version of Cosmic C compiler 4.5c. Both software tools are available on the ST

internet site http://www.st.com/mcu.

You can also contact your local ST sales office for obtaining this software.

Cosmic C compiler must be installed in the path without spaces in the name, i.e.

"C:\COSMIC\CXST7_16K\". The default installation path cannot be used.

In order to compile the whole project correctly the user has to modify the file

USB_FS_7265_32K.MAK and select the correct path to the project in the PRJ_PATH

definition.

In case the recommended path for Cosmic C compiler is not used, the user has to also

modify the file USB_FS_7265_32K.LKF and modify the pre-set path to correct the Cosmic C

compiler location.

The firmware is based on the standard ST7 USB Full Speed library. This library can also be

downloaded from ST internet site http://www.st.com/mcu.

One part of the source code is dedicated to Data Transfer Coprocessor, which is part of the

ST72651 MCU. This code can be compiled using the tools included with the source code. In

the "DTC Compiler\Fsm" part of the source code you can find the batch file all.bat which

automatically compiles the source files for DTC and copies the result into the correct project

directory. This batch file should be modified in order to change user paths to the project. The

DTC implements the RS232 serial communication protocol.
