A low-cost frequency relay implemented in a soft-core processor with FreeRTOS. Written in C.
The low-cost frequency relay aims to dynamical and intelligently regulate household electricity usage, thus saving energy and minimizing power network instability.
The entire workspace is in the ./workspace directory, which on my system is in the root of H: drive.
The sopinfo file is in ./workspace/hardware_configuration.
The projects (both the bsp and the actual project) are in ./workspace/hardware_configuration/software.
The main logic is in file state_machine.c, which implements the state machine task. freq_irq.c implements the frequency interrrupt handler. load_control.c implements the load states utility functions and the red_led_control task. threshold_control.c implements the PS/2 interrupt handler and the threshold utility functions. timer.c implements the 0.5sec timer used in the state machine. vga.c implements the vga task. panic.h is the panic() function that prints an error message and hangs the system. main.c is the entry point of our system and initialises all subsystems and calls scheduler.
For a complete project report see ./doc/report.pdf.
Import the project folder into eclipse. Import the bsp (freq_relay_proj_bsp) first, then freq_relay_proj.
It may be a good idea to put the whole workspace directory in the H: drive, as some of the eclipse-generated code may have reference to absolute path.
