My diploma project with PIC16F877 microcontroller

Description:

. Synchronous generator excitation control system (my diploma project). I designed, built and programmed a system that is able to modify the voltage on the excitation of a synchronous generator. The system is composed of a buck converter and a control circuit board built around the PIC16F877 microcontroller. The circuit board can be controlled remotely, from a PC through an application that is running on the PC, via RS232 port. The controller board also contains a Nokia 3310 display witch shows the PWM duty cycle and push-button’s functions.

– the board can be used also as development board

– the microcontroller software was wrote in assembler language

– the hex file is loaded on the PIC16F877 microcontroller using David Tait programmer and WinPic800 software

– the application running on the PC was wrote in Delphi
