A Microcontroller based Oscillator that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. I used Stm32f microcontroller to complete this project. You can generate up to 8 different types of waves. Also Wave period and frequency are adjustable. You can find the complete report here.
Microcontroller generate PWM and change its duty cycle frequently to shape the right wave. afterward, PWM goes through a LCF type T and then a LCF type L to clear the noises. Finally we have a nice and smooth wave. 😁
- Sine Wave
- Square Wave
- Triangle Wave
- Sawtooth Wave
- Stair Wave (12)
- Rectified Sine Wave (14)
- Vertically Segmented Sine Wave (17)
- Sine Modulation of Square Wave (18)
You can adjust the domain from scale 4 to 10 which 10 being the highest and the bigest size. and the frequency is adjustable from 1hz to 20kHz.
load the hex file into the microcontroller in proteus file. set 96 and 97 for amilitude and frequency respectively in proteus file. and hit the run button.
Project is open for any contribution and futher development. Please feel free to contact me if you have any doubt or problem. here's my email. 🍻
I would like to express my gratitude to amazing Fatemeh that helped me to complete this wonderful job. it wasn't possible without her.
