Programming tool for ST10F family of microcontrollers

This is my bachelor's thesis at Faculty of Information Technology at Czech Technical University in Prague. It is publicly available in the CTU Digital Library. It's written in Slovak language. Programming languages and main technologies used were C, C++, Assembler, CMake and CTest.

Abstract

Aim of this bachelor's thesis is a creation of cross-platform tool allowing to write, read and erase a program memory of microcontrollers of ST10F family and its testing. Based on analysis of existing means for microcontroller programming, literature about these microcontrollers and documentation of Microsoft Windows and GNU/Linux operating systems, a new application is designed and implemented. Result of the thesis is a cross-platform programming tool for writing, reading and erasing of a program memory of ST10F168 and ST10F269 microcontrollers.

The programming tool is used by AŽD Praha s.r.o. company for maintenance of electronic units of railway electric circuits. It is beneficial to technicians and developers, who deal with maintenance and development of a systems which have these programmable devices planted.

In attachment of the thesis, source codes of the programming tool can be found.

Results of the work

The aim of this thesis was analysis, design and implementation of application for erasing, writing and reading internal program FLASH memory of ST10F168 and ST10F269 microcontrollers and testing the resulting application under supported operating systems. During the work I encountered errors of ST10F269 microcontroller which I resolved thanks to the information from literature and my own experiments. The application can erase, write and read internal program FLASH memory of ST10F168 and ST10F269 microcontrollers and identify a connected microcontroller. Application can be built as executable for MS Windows 7 to MS Windows 10, GNU/Linux and FreeBSD. It was tested in the environment of these operating systems. It has command-line user interface, built-in help message and it can list supported serial line speeds and operate on arbitrary serial port name. It has an option for showing information messages and operation progress.

User can erase whole FLASH memory or only selected blocks of it. For reading, user can specify how many bytes from address 0 will be read and name of the output file to which the bytes will be saved. For writing, user can specify if the whole memory or only blocks affected by write operation will be erased, and the name of file containing data for writing from address 0. Result of the write operation can be checked by reading back content of the memory. Input and output files are treated as binary files.

In the future the application could be extended by adding Intel Hex file format support for input and output files, possibility of user-specified start memory address for reading and writing, and support for other models of microcontrollers.
