LightRanger 10 Click

LightRanger 10 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 : May 2022.
  • Type : I2C type

Software Support

Example Description

This example demonstrates the use of LightRanger 10 Click board by reading and displaying the target object distance in millimeters.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.LightRanger10

Example Key Functions

Application Init

Initializes the driver, performs the Click default configuration, and then calibrates the sensor to the object positioned at 200mm distance from the sensor.

void application_init ( void )
{
log_cfg_t log_cfg;
lightranger10_cfg_t lightranger10_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
lightranger10_cfg_setup( &lightranger10_cfg );
LIGHTRANGER10_MAP_MIKROBUS( lightranger10_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == lightranger10_init( &lightranger10, &lightranger10_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( LIGHTRANGER10_ERROR == lightranger10_default_cfg ( &lightranger10 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_printf( &logger, " --- Sensor calibration --- \r\n" );
log_printf( &logger, " Place an object at 200mm distance from sensor in the next 5 seconds.\r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " Sensor calibration is in progress...\r\n" );
if ( LIGHTRANGER10_ERROR == lightranger10_calibrate_distance ( &lightranger10, 200 ) )
{
log_error( &logger, " Sensor calibration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Waits for the data ready interrupt, then clears the interrupt and reads the target distance in millimeters and displays the results on the USB UART every 200ms approximately.

void application_task ( void )
{
while ( lightranger10_get_int_pin ( &lightranger10 ) );
uint16_t distance_mm;
if ( ( LIGHTRANGER10_OK == lightranger10_clear_interrupts ( &lightranger10 ) ) &&
( LIGHTRANGER10_OK == lightranger10_get_distance ( &lightranger10, &distance_mm ) ) )
{
log_printf ( &logger, " Distance: %u mm \r\n\n", distance_mm );
}
}

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.
