Project Description

The goal of the project is to create an LED Controller App that can adjust LED brightness/intensity using push buttons and display relevant data on a computer using Python. The project involves the use of Microcontroller peripherals such as UART and Timer, along with efficient coding practices.

Project Features

LED Control Modes:

• Pressing PB1 toggles the system between ON and OFF modes.
• In ON mode, the LED operates at 95-100% intensity, adjustable with a Potentiometer using PWM.
• In OFF mode, the LED turns off, and the system enters low power Idle() mode.

Blinking LED:

• Pressing PB2 makes the LED blink at 100% intensity with a 500ms interval.
• Pressing PB2 again stops the LED blinking.

Python Script:

• Captures and stores intensity levels and average PWM voltage output over 1 minute.
• Generates CSV/Excel file with proper indexing and column names.
• Plots intensity levels and average voltage output vs. time on separate graphs.

Graphical Display:

• Two graphs displaying intensity levels or PWM voltage (Vpwm) against time.
• Graph titles, X and Y axis labels, and pulse frequency information.

Project Implementation

Hardware Kit:

• Use of Microcontroller peripherals: UART, Timer, and IO (CN) interrupts.
• Efficient power usage through clock switching and sleep/idle modes.

Code Organization:

• Implement in ANSI C with IO(CN) and Timer interrupts.
• Detailed comments, proper variable names, and adherence to efficient coding practices.

Pulse Width Modulation (PWM):

• Generate PWM signals on Pin 12, controlling LED brightness with Potentiometer input.

State Diagram:

• Utilizing microcontroller-specific registers, bit names, and flags.
