Library Description

Initializes and defines UART bus driver, and defines driver's functions for reading Heart Rate data uses Heart Rate 9 clicks.

Key functions:

  • uint8_t heartrate9_read_byte() - Read Single Byte
  • uint8_t heartrate9_byte_ready() - Check for new byte received/li>

Examples description

The application is composed of three sections :

  • System Initialization - Initializes UART module
  • Application Initialization - Initializes Driver init and logs instructions on commands and format of response data
  • Application Task - Waits for valid user input and executes functions based on set of valid commands
void applicationTask()
{
    char hr9_rx_data;
    char console_rx_data;
    
    uint8_t hr9_drdy_flag;
    uint8_t console_drdy;

    console_drdy = UART_Rdy_Ptr( );

    if ( console_drdy != 0 )
    {
        console_rx_data = UART_Rd_Ptr( );
        
        if ( ( console_rx_data == 's' ) || ( console_rx_data == 'S' ) )
        {
            mikrobus_logWrite( " >> [s or S] - START << ", _LOG_LINE );
            start_app_flag = 1;
        }
        
		if ( ( console_rx_data == 'b' ) || ( console_rx_data == 'B' ) )
        {
            mikrobus_logWrite( " >> [b or B] - BREAK << ", _LOG_LINE );
            start_app_flag = 0;
        }
        
		if ( ( console_rx_data == 'h' ) || ( console_rx_data == 'H' ) )
        {
            mikrobus_logWrite( " >> [h or H] - HELP << ", _LOG_LINE );
            heartrate9_help( );
        }
    }
    
    if ( start_app_flag == 1 )
    {
        hr9_drdy_flag = heartrate9_byte_ready( );

        if ( 1 == hr9_drdy_flag )
        {
            hr9_rx_data = heartrate9_read_byte( );
            mikrobus_logWrite( &hr9_rx_data, _LOG_BYTE );
        }
    }
}


Commands : 'S or s' - Start logging 'B or s' - Break logging 'H or h' - Help

Additional Functions :

  • void heartrate9_help() - commands and response data help

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 clickUSB 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.

TDC Click

0

TDC Click is a compact add-on board that recognizes events and provides a digital representation of the time they occurred. This board features the TDC7200, a time-to-digital converter from Texas Instruments. The Time to Digital Converter (TDC) performs the function of a stopwatch and measures the elapsed time (time-of-flight or TOF) between a START pulse and up to five STOP pulses. The ability to measure from START to multiple STOPs gives users the flexibility to select which STOP pulse yields the best echo performance.
