AVR-RDA5807 - TM1638 -PAM8403 FM STEREO RADIOThis project uses the library RDA5807 from Ricardo PU2CLR. All credits and acknowledgements goes for his great work . What is it? This project was designed around the RDA5807 DSP FM Radio chip. Interfaced with an ATMega8 clocked at 16mhz and utilizing the breakout board TM1638 which is widely available and offers 8 seven segment displays and 8 LEDS and 8 switches to form the front interface of this project FM Stereo Radio. An audio Amplifier PAM8403 Stereo Class D is also provided on the board and provides enough kick for this project ! Two regulators provide the necessary supplies 5v and 3v3. FM input is through an SMA edge connector and diode clamping is provided on the pcb. I have optimized the code to show the status of every button on the seven segment . Thus pressing the button will show the status as : Button 1: Manual tune Down Button 2: Manual tune Up Button 3 : Frequency scan - shows dial of frequency scanning Button 4 : Vol Down (With Level of Volume) Button 5 : Vol up (W...
