LR 15 Click

LR 15 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 : Sep 2024.
  • Type : UART type

Example Description

This example demonstrates the use of LR 15 Click board by showing the communication between two Click boards configured in TEST mode.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.LR15

Application Init

Initializes the driver and logger.

void application_init ( void )
{
log_cfg_t log_cfg;
lr15_cfg_t lr15_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
lr15_cfg_setup( &lr15_cfg );
LR15_MAP_MIKROBUS( lr15_cfg, MIKROBUS_1 );
if ( UART_ERROR == lr15_init( &lr15, &lr15_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
app_state = LR15_POWER_UP;
log_printf( &logger, ">>> APP STATE - POWER UP <<<\r\n\n" );
}
#define LR15_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.

Application Task

Application task is split in few stages:

  • LR15_POWER_UP:

    Powers up the device, performs a device factory reset and reads system information.

  • LR15_CONFIG_EXAMPLE:

    Configures device for the LoRa P2P network mode.

  • LR15_EXAMPLE:

    Performs a LoRa P2P test example by exchanging messages with another LR 14 Click board.

void application_task ( void )
{
switch ( app_state )
{
{
if ( LR15_OK == lr15_power_up( &lr15 ) )
{
app_state = LR15_CONFIG_EXAMPLE;
log_printf( &logger, ">>> APP STATE - CONFIG EXAMPLE <<<\r\n\n" );
}
break;
}
{
if ( LR15_OK == lr15_config_example( &lr15 ) )
{
app_state = LR15_EXAMPLE;
log_printf( &logger, ">>> APP STATE - EXAMPLE <<<\r\n\n" );
}
break;
}
{
lr15_example( &lr15 );
break;
}
default:
{
log_error( &logger, " APP STATE." );
break;
}
}
}

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.
