Examples
This folder has some examples that might help you to use the RDA5807 Arduino Library in your receiver project. If you find some error or problem during your implementation, please let me know.
This project is about a library to control the RDA5807 device and the focus of this project is the library and its functionalities. Please, don’t ask me to assist you in your: displays, encoders, LED, buttons or something else out the library scope. Thanks.
The examples stored in this folder are made to assist you to build your own sketch. Therefore, it is important to say that there was no care with the layout. This part of the project stays with you.
The RDA5807_01_SERIAL_MONITOR folder shows how you can check your circuit by using just the Arduino IDE Serial Monitor to control the receiver. Check the examples with Atmega328 and ESP32. In the sketch you will find the wireup with Atmega328 or ESP32 and RDA5807 device.
The following table shows the main examples implemented in this library. These examples can guide you to build your own receiver.

Minimalist receiver based on RDA5807
The following code illustrates a minimalist implementation of a receiver based on RDA5807 and this library. For this receiver, the user has two pushbuttons to tune station (Seek Up and Seek Down).
#include <RDA5807.h> // It is a minimal receicer with two push buttons (ATmega328 - Uno, Nano etc)
RDA5807 rx;
void setup() {
pinMode(4, INPUT_PULLUP); // Arduino pin 4 - Seek station down
pinMode(5, INPUT_PULLUP); // Arduino pin 5 - Seek station up
rx.setup(); // Starts the receiver with default parameters
rx.setFrequency(10390); // Tunes in 103.9 MHz - Switch to your local favorite station
}
void loop() {
if (digitalRead(4) == LOW) rx.seek(RDA_SEEK_WRAP,RDA_SEEK_DOWN);
if (digitalRead(5) == LOW) rx.seek(RDA_SEEK_WRAP,RDA_SEEK_UP);
delay(200);
