Ultrasonic 5 Click

Ultrasonic 5 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.


Click Library

  • Author : Stefan Filipovic
  • Date : Jun 2023.
  • Type : SPI type

Software Support

Example Description

This example demonstrates the use of Ultrasonic 5 Click board by reading the measurements from the connected ultrasonic sensor and displaying it on a Serial Plot.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ultrasonic5

Example Key Functions

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
ultrasonic5_cfg_t ultrasonic5_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ultrasonic5_cfg_setup( &ultrasonic5_cfg );
ULTRASONIC5_MAP_MIKROBUS( ultrasonic5_cfg, MIKROBUS_1 );
if ( ULTRASONIC5_OK != ultrasonic5_init( &ultrasonic5, &ultrasonic5_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( ULTRASONIC5_OK != ultrasonic5_default_cfg ( &ultrasonic5 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Performs a burst generation which starts the measurement and then reads the next 200 ADC samples and displays the results on the USB UART (SerialPlot).

void application_task ( void )
{
float voltage = 0;
// Burst generation / Start measurement
ultrasonic5_pwm_start( &ultrasonic5 );
ultrasonic5_clear_io1_pin ( &ultrasonic5 );
Delay_500us ( );
ultrasonic5_set_io1_pin ( &ultrasonic5 );
ultrasonic5_pwm_stop( &ultrasonic5 );
// Read and log the next 200 ADC samples which we will plot on a Serial Plotter
for ( uint16_t cnt = 0; cnt < 200; cnt++ )
{
if ( ULTRASONIC5_OK == ultrasonic5_read_an_pin_voltage ( &ultrasonic5, &voltage ) )
{
log_printf( &logger, "%.3f\r\n", voltage );
}
}
}
#define ULTRASONIC5_DEF_DYTY
Definition ultrasonic5.h:221
err_t ultrasonic5_set_duty_cycle(ultrasonic5_t *ctx, float duty_cycle)
Ultrasonic 5 sets PWM duty cycle.
void ultrasonic5_set_io1_pin(ultrasonic5_t *ctx)
Ultrasonic 5 set io1 pin function.
err_t ultrasonic5_pwm_stop(ultrasonic5_t *ctx)
Ultrasonic 5 stop PWM module.
void application_task(void)

Note

In order to get valid measuremets a proper ultrasonic sensor must be connected to OUTA and OUTB. We have used an UTR-1440K-TT-R sensor for the test. We recommend using the SerialPlot tool for data visualizing. Refer to the datasheet "Application Curves" section in order to check and compare the results from the plotter.

Application Output

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.

Additional Notes and Information

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.
