Library Description

The library covers all the necessary functions to control RF Switch Click board. The library contains a function which switching signal between RF Channel 1 and 2.

Key functions:

• void rfswitch_set_mode ( uint8_t enable ) - Set Power mode state.
• void rfswitch_sel_state ( uint8_t sel_state ) - Set SEL pin state.
• void rfswitch_select_channel ( uint8_t select_channel ) - Select RF channel.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, sets CS and PWM pins as output and start write log.
• Application Initialization - Initialization driver enable's - GPIO, also write log.
• Application Task - (code snippet) This is a example which demonstrates the use of RF Switch Click board. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( )
{
    mikrobus_logWrite( "  Switch to RF Port 1  ", _LOG_LINE );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    rfswitch_select_channel( RFSWITCH_SELECT_CHANNEL_1 );
    Delay_ms( 5000 );

    mikrobus_logWrite( "  Switch to RF Port 2  ", _LOG_LINE );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    rfswitch_select_channel( RFSWITCH_SELECT_CHANNEL_2 );
    Delay_ms( 5000 );
}

Other mikroE Libraries used in the example:

• UART

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or 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.
