Introduction
The challenge in this project is 1kB or less program size to interface Si5351 chip. I took the challenge myself. In arduino 1kB is just enough to blink LED with some sequence. Thats the beauty of Arduino ..LOL
Project Specification:
- Use the Si5351 as variable frequency oscillator to cover CW range
- Ex : 7000 to 7050 KHz
- 10100 to 10150 KHz
- 14000 to 14050 KHz
- 3500 to 3550 KHz etc…
- To change the frequency using potentiometer
- CLK2 as beat frequency oscillator for required frequency
- Control the VFO or ON/OFF the CLK0 output with morse key
- 1 digital output for TX/RX relay
- Operating voltage is 3.3V for ATTiny13 and Si5351
