Library Description

Library provides functions for communication with Click board, specific ones to configure device, setting frequency, frequency deviation, baudrate, and one for sending(transmit) data.

Key functions:

• void ismtx_initial_cfg ( void ) - Function for initial configuration
• uint8_t ismtx_set_frequency ( uint32_t freq ) - Function for setting transmit frequency
• void ismtx_send_data ( uint8_t *tx_data, uint8_t tx_len ) - Function for transmiting data

Examples description

The application is composed of three sections :

• System Initialization - Initialization of CS pin and LOG module
• Application Initialization - Initialization for configuration, resets device, sets default configuration, and sets parameters for communication.
• Application Task - Sends predefined data every second.

void application_task ( )
{    
    ismtx_send_data( &data_send[ 0 ], 8 );
    mikrobus_logWrite( " *  Transmit done! *  ", _LOG_LINE );
    Delay_ms( 1000 );
}

Additional Functions :

• void manchester_spi_init ( void ) - Wrapper function over SPI init for sending data
• void normal_spi_init ( void ) - Wrapper function over SPI init for normal communication

Other mikroE Libraries used in the example:

• SPI
• 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.
