Library Description
The library covers all the necessary functions to control Clock Gen 5 Click board™. Library performs a standard SPI interface communication.
Key functions:
void clockgen5_out_enable ( uint8_t en_out )
- Enable output function.void clockgen5_set_config ( uint8_t cfg )
- Set configuration function.void clockgen5_set_freq ( float freq )
- Set frequency function.Examples description
The application is composed of three sections :
void application_task ( )
{
clockgen5_set_freq( 12000.0 );
mikrobus_logWrite( "-----------------------", _LOG_LINE );
mikrobus_logWrite( " 12.0 MHz ", _LOG_LINE );
Delay_ms( 3000 );
clockgen5_set_freq( 8000.0 );
mikrobus_logWrite( "-----------------------", _LOG_LINE );
mikrobus_logWrite( " 8.0 MHz ", _LOG_LINE );
Delay_ms( 3000 );
clockgen5_set_freq( 5500.0 );

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.
