UWB 3 click

‍UWB 3 Click is a compact add-on board that brings Ultra-Wideband communication to your application. This board features the DWM3001, a fully integrated UWB transceiver module from Qorvo. The module integrates the DW3110 IC, nRF52833 MCU, planar UWB antenna, accelerometer, power management, and crystal. It is a fully calibrated, tested, and validated design. This Click board™ makes the perfect solution for the development of precision real-time location systems (RTLS) using two-way ranging or TDoA schemes in various markets, location-aware wireless sensor networks (WSNs), and more.

Click library

• Author : Stefan Filipovic
• Date : Sep 2023.
• Type : UART type

Software Support

We provide a library for the UWB 3 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 UWB 3 Click driver.

Standard key functions :

• uwb3_cfg_setup Config Object Initialization function.

  void uwb3_cfg_setup ( uwb3_cfg_t *cfg );

• uwb3_init Initialization function.

  err_t uwb3_init ( uwb3_t *ctx, uwb3_cfg_t *cfg );

Example key functions :

• uwb3_send_cmd This function sends a specified command to the click module.

  void uwb3_send_cmd ( uwb3_t *ctx, uint8_t *cmd );

• uwb3_send_cmd_with_parameter This function sends a command with specified parameter to the click module.

  void uwb3_send_cmd_with_parameter ( uwb3_t *ctx, uint8_t *cmd, uint8_t *param );

• uwb3_reset_device This function resets the device by toggling the RST pin state.

  void uwb3_reset_device ( uwb3_t *ctx );

Example Description

‍This example demonstrates the use of an UWB 3 click board by showing the communication between the two click boards.

The demo application is composed of two sections :

Application Init

‍Initializes the driver and configures the click board for the selected application mode.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    uwb3_cfg_t uwb3_cfg;  
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    uwb3_cfg_setup( &uwb3_cfg );
    UWB3_MAP_MIKROBUS( uwb3_cfg, MIKROBUS_1 );
    if ( UART_ERROR == uwb3_init( &uwb3, &uwb3_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    // Clear buffers
    uwb3_process( &uwb3 );
    uwb3_clear_app_buf( );
    
    // Switch to stop mode
    uwb3_send_cmd ( &uwb3, UWB3_CMD_STOP );
    uwb3_display_response ( &uwb3 );
    Delay_ms ( 1000 );
    
#if ( DEMO_APP == APP_RESPONDER_1 )
    uwb3_send_cmd_with_parameter ( &uwb3, UWB3_CMD_RESPF, RESPONDER_1_CONFIG );
    uwb3_display_response ( &uwb3 );
    log_printf( &logger, "Application Mode: Responder 1\r\n" );
#elif ( DEMO_APP == APP_RESPONDER_2 )
    uwb3_send_cmd_with_parameter ( &uwb3, UWB3_CMD_RESPF, RESPONDER_2_CONFIG );
    uwb3_display_response ( &uwb3 );
    log_printf( &logger, "Application Mode: Responder 2\r\n" );
#else
    uwb3_send_cmd_with_parameter ( &uwb3, UWB3_CMD_INITF, INITIATOR_CONFIG );
    uwb3_display_response ( &uwb3 );
    log_printf( &logger, "Application Mode: Initiator\r\n" );
#endif
    
    uwb3_clear_app_buf( );
    log_info( &logger, " Application Task " );
}

Application Task

‍Reads and processes all incoming ranging block messages and displays them

on the USB UART. One click board should be configured to initiator mode and the others to responder 1 or 2. The initiator click displays the address and distance of each responder nodes, while the responder click boards displays the address and distance of the initiator click board.

void application_task ( void )
{
    if ( UWB3_OK == uwb3_process( &uwb3 ) ) 
    {
        if ( UWB3_OK == uwb3_parse_ranging_block ( ) )
        {
            uwb3_clear_app_buf( );
        }
    }
}

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.UWB3

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.
