The Heart Rate 9 Click is a Click board™ which features PIC16F1779 8-bit MCU and SFH 7060 heart rate and pulse oximetry monitoring sensor.
We provide a library for the HeartRate9 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.
This library contains API for HeartRate9 Click driver.
Config Object Initialization function.
void heartrate9_cfg_setup ( heartrate9_cfg_t *cfg );
Initialization function.
HEARTRATE9_RETVAL heartrate9_init ( heartrate9_t *ctx, heartrate9_cfg_t *cfg );
Click Default Configuration function.
void heartrate9_default_cfg ( heartrate9_t *ctx );
Heart Rate 9 data writing function.
err_t heartrate9_generic_write ( heartrate9_t *ctx, char *data_buf, uint16_t len );
Heart Rate 9 data reading function.
err_t heartrate9_generic_read ( heartrate9_t *ctx, char *data_buf, uint16_t max_len );
Sets state of the rst pin setting.
void heartrate9_set_rst ( heartrate9_t *ctx, uint8_t state );
This example reads and processes data from Heart Rate 9 clicks.
The demo application is composed of two sections :
Initializes driver and wake-up module.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
heartrate9_cfg_t heartrate9_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
// Click initialization.
heartrate9_cfg_setup( &heartrate9_cfg );
HEARTRATE9_MAP_MIKROBUS( heartrate9_cfg, MIKROBUS_1 );
err_t init_flag = heartrate9_init( &heartrate9, &heartrate9_cfg );
if ( init_flag == UART_ERROR )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
app_buf_len = 0;
app_buf_cnt = 0;
}
Reads the received data and logs it.
void application_task ( void )
{
heartrate9_process();
if ( app_buf_len > 0 )
{
log_printf( &logger, "%s", app_buf );
heartrate9_clear_app_buf( );
}
}
Data structure is:
AA;BB;CC;DD;EE;
AA -> Data header.\ BB -> Red diode.\ CC -> IR diode.\ DD -> Green diode.\ EE -> BPM.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

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. UART terminal is available in all Mikroelektronika compilers.
