Library Description

The RadioStation click board™ communicates with the controller by using the I2C/2-wire interface. The library contains a wide set of functions for the complete control over the RadioStation click. Some of the functions also return the status, so it is possible to take an action in the case of error.

uint8_t RADIOSTATION_SetTuneFrequency(uint16_t freq)- Sets tune frequency

uint8_t RADIOSTATION_SetTunePower(uint8_t voltage, uint8_t capacitance)- Sets tune power

uint8_t RADIOSTATION_GetTuneMeasure(uint16_t freq, uint8_t capacitance)- Reads tuning measurements

Examples Description

Demo application shows how to configure RadioStation click to receive the signal from the audio connector and broadcast it on 100.00 MHz frequency.

The application is composed of three sections:

• System initialization - Initializes GPIO pins, I2C peripheral used for communication between RadioStation click and MCU, and UART used for logging. This function also initializes driver.
• Application initialization - (Code snippet) Powers on RadioStation click and setups frequency for signal emission and writes a message to UART when emission is started.
• Application task - Sequentially reads measurements of the signal quality.

void applicationInit()
{
    status_ = RADIOSTATION_PowerUp();
    RADIOSTATION_GetRevision(&buff[0]);
    status_ = RADIOSTATION_SetTuneFrequency(transmitFrequency);
    RADIOSTATION_BusyWaitForSTCINT();
    RADIOSTATION_GetTuneStatus(1, &buff[0]);
    status_ = RADIOSTATION_SetTunePower(115, 0);
    RADIOSTATION_BusyWaitForSTCINT();
    RADIOSTATION_GetTuneStatus(1, &buff[0]);
    UART1_Write_Text("Radio Click now broadcastig at selected frequency");
}

Other mikroE Libraries used in the example: 

• UART 

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
