/*
Test RDS functions using Serial Monitor.
This sketch is useful to check how the RDS work and how the local stations provide this service.
For example: I have noticed in my location that some stations send wrong time information. So, for these stations,
the RDS time functions implemented by this library seem do not work fine
To use this aplication, please select the Arduino IDE Serial Monitor.
Type ? to see the instructions.
Arduino Pro Mini and RDA5807 wire up
| Device RDA5807 | Arduino Pin |
| --------------- | ------------ |
| SDIO | A4 |
| SCLK | A5 |
ATTENTION:
Please, avoid using the computer connected to the mains during testing. Used just the battery of your computer.
This sketch was tested on ATmega328 based board. If you are not using a ATmega328, please check the pins of your board.
