Abstract

The article presents innovative approach to RDS (Radio Data System). In the proposed solution, the microcontroller communicates with the system of the radio receiver via I2C bus, checking individual memory addresses, where the current data from the radio data system are stored. Selection of a radio station or adjusting of radio frequency is made through the user menu on OLED I2C display (I2C – two-way serial bus used for data transfer). The transmission form uses only two data lines: SDA (serial data) and SCL (serial clock). These two lines are used to transfer all information between devices connected to I2C bus). By means of a microswitch or infrared remote control a user may select a radio station, set an alarm and change a mobile radio set into a comfortable alarm clock. The device has a connection for additional external Wi-Fi and Bluetooth modules, and thanks to them it may become an universal, mobile central station in IOT networks. Thanks to this, a user may always have at hand a small radio set, which may be used additionally - for instance in a smart home – as the controller that switches the light on and off, check temperature in individual rooms of a factory or is used as a remote controller of a gate to the premises.
