This project help you to build a Frequency Generator (from 10Khz to 125Mhz) using a Si5351 Module on Arduino (UNO R3, Nano, etc...) The schematic attached use a LCD 20x2 compatible Hitachi HD44780 with 74HC595 shift register integrated circuit (see "how drive a HD44780 LCD using a 74HC595 shift register")
- si5351 Etherkit Library (found here: https://github.com/etherkit/Si5351Arduino)
- LiquidCrystal 74HC595 Library (found here: https://github.com/matmunk/LiquidCrystal_74HC595)
- IU8NQI Utils Library (included in the IU8NQI_Utils folder)
- Arduino (UNO R3, Nano, etc..)
- Si5351 module
- LCD 20x2 compatible Hitachi HD44780
- 1 Rotary Encoder With Push Button
- 1 Transistor BC547
- 3 Polyester Capacitor 100 nf
The output signal is locate on CLK0 output (pin 1) of si5351 module
Long press button for swap between Frequency and other functions menu
Short press button for navigate through the functions
- in the Frequency function you can navigate between every digits
- in the other functions you can navigate between: ON/OFF signal, Brightness and Power output
