ATmega328 Microcontroller-based Sinusoidal PWM Signal Generation with Dynamic Feedback Control
Budget: ₹4,999 – ₹5,000 INR
Project Overview:
We are seeking an experienced embedded systems developer to implement a PWM signal generator on an ATmega328 microcontroller. The project involves generating sinusoidal waveforms using Pulse Width Modulation (PWM) on specific output pins with dynamic feedback control. Additionally, inverted signals should be generated on complementary pins. The system will read analog feedback, apply smoothing, and adjust the PWM signal accordingly in real time.
Project Scope:
PWM Signal Generation:
Use Fast PWM mode on the ATmega328 microcontroller to generate sinusoidal waveforms on the following pins:
PD6 (OC0A): Primary signal output
PD5 (OC0B): Secondary signal output
Generate inverted signals on the complementary pins:
PB3 (OC2A): Inverted signal output
PD3 (OC2B): Inverted signal output
Analog Feedback Control: Implement a feedback mechanism where analog input is read (from PC0), smoothed, and used to dynamically adjust the PWM signal in real time.
Sinusoidal LUT Implementation: Utilize a sine lookup table (LUT) to drive the PWM signal. Ensure smooth transitions between values and proper synchronization of the inverted signal.
Interrupt-based Signal Updates: Use ISRs (Timer2 overflow) to update PWM values on each cycle based on the LUT and feedback.
Inverted Signal: Ensure inverted PWM signals are generated on PB3 and PD3 in sync with the main signal on PD6 and PD5.
Performance Optimization: Optimize the feedback loop and ISR to ensure smooth and efficient signal generation without missing cycles.
Technical Requirements:
ATmega328 microcontroller programming.
Knowledge of Timer/Counter configurations, PWM signal generation, and Fast PWM mode.
Experience with analog feedback systems and signal smoothing techniques.
Ability to generate inverted signals on complementary pins.
Proficiency in embedded C and AVR-GCC toolchain.
Deliverables:
Well-documented and optimized source code.
Simulation/test results demonstrating the proper operation of the PWM generation, feedback system, and inverted signal output.
A brief project report summarizing the implementation and key considerations.
Preferred Skills:
ATmega328 microcontroller programming experience.
Strong understanding of PWM signal generation and control systems.
Experience in generating synchronized inverted signals.
Ability to write clean, maintainable code with clear documentation.
Please submit your proposals with details of your previous embedded systems experience and a timeline for project completion.
