Heart Rate 7 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

heartrate7_cfg_setup
Config Object Initialization function.
void heartrate7_cfg_setup ( heartrate7_cfg_t *cfg );
heartrate7_init
Initialization function.
err_t heartrate7_init ( heartrate7_t *ctx, heartrate7_cfg_t *cfg );
heartrate7_default_cfg
Click Default Configuration function.
err_t heartrate7_default_cfg ( heartrate7_t *ctx );
heartrate7_write_reg
Heart Rate 7 register write function.
void heartrate7_write_reg( heartrate7_t *ctx, uint8_t reg_addr, uint32_t write_data );
heartrate7_read_reg
Heart Rate 7 register reading function.
uint32_t heartrate7_read_reg( heartrate7_t *ctx, uint8_t reg_addr );
heartrate7_sw_reset
Heart Rate 7 software reset function.
void heartrate7_sw_reset( heartrate7_t *ctx );
Configures the micro controller for communication and initializes the Click board.

LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
heartrate7_cfg_setup( &heartrate7_cfg );

{
log_error( &logger, " Default configuration." );
for ( ; ; );

log_info( &logger, " Application Task " );
}
This section shows how the data is processed and sent to the MikroPlot application.
void application_task ( void )
{
sensor_value = heartrate7_get_aled1_val( &heartrate7 );
log_printf( &logger, "%lu,%lu \r\n", sensor_value, time );
time += 10;
Delay_ms ( 10 );
}
For testing this example application SerialPlot was used. There you can see heart rate graphicly shown.
This Click board can be interfaced and monitored in two ways:
- Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
- UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
