Name: Atharva Nandanwar

This repository contains source files for Principles of Embedded Software Project 5 - UART and Circular Buffer

Source Folder:

main.c/h - main subroutine
circular_buffer/circular_buffer.c/h - functions and structure definition for circular buffer
led_control/led_control.c/h - functions to control LED
logger/logger.c/h - functions to do logging
logger/errno.c/h - error handling routines
logger/timestamp.c/h - timestamp functionality
test/test.c/h - test cases and test subroutine
uart/uart.c/h - uart subroutines, initialization, and operation drivers
uctest - uCunit testing files
common.h - common include file for system-wide implementation

Observations:

There was serious problems with how integration would work in this aspect. How do I interface interrupt service routines with circular buffer operations? How do I interface UART functions with circular buffer? How do I manage getchar and putchar functionality with everything in the system? *Making global buffers was the way to do
The way I had designed logger required me to implement a lot of complicated printf operations. I rather used sprintf to format data into a string and printing the string directly.
During Interrupt based Application Mode, the program switches to Overrun condition, but it doesn't raise the interrupt. I did not address this problem in this program.

Installation/Execution Notes:

Use basic options to compile RUN, LOG, and TEST builds from Build Targets.

Compiler - gcc-arm-none-eabi

There are different functionalities that can be configured in RUN and LOG mode:

You will have to go to common.h to edit different modes. Comment out the mode you want, and comment others.

Note:

In application mode, report is printed after every 50th character is received.
