Software Support

We provide a library for the LightRanger 9 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.

Library Description

This library contains API for LightRanger 9 Click driver.

Standard key functions :

Example Description

This example demonstrates the use of LightRanger 9 click board by reading and displaying all four sub-captures data measurements on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
lightranger9_cfg_t lightranger9_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
lightranger9_cfg_setup( &lightranger9_cfg );
LIGHTRANGER9_MAP_MIKROBUS( lightranger9_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == lightranger9_init( &lightranger9, &lightranger9_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( LIGHTRANGER9_ERROR == lightranger9_default_cfg ( &lightranger9 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads all four sub-captures data approximately every 500ms and logs them to the USB UART

in a form of two object 8x8 maps. Other data such as DIE temperature, ambient light, system tick, etc., are also being displayed.

void application_task ( void )
{
while ( lightranger9_get_int_pin ( &lightranger9 ) );
if ( ( LIGHTRANGER9_OK == lightranger9_clear_interrupts ( &lightranger9 ) ) &&
( LIGHTRANGER9_OK == lightranger9_get_capture ( &lightranger9, &capture ) ) )
{
lightranger9_log_results ( capture );
}
}

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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.LightRanger9

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.
