Click library

  • Author : Nenad Filipovic
  • Date : Nov 2023.
  • Type : UART type

Software Support

We provide a library for the LYRA 24P 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 LYRA 24P Click driver.

Standard key functions :

  • lyra24p_cfg_setup Config Object Initialization function.

    void lyra24p_cfg_setup ( lyra24p_cfg_t *cfg );
  • lyra24p_init Initialization function.

    err_t lyra24p_init ( lyra24p_t *ctx, lyra24p_cfg_t *cfg );

Example key functions :

  • lyra24p_write_command This function writes a desired command by using UART serial interface.

    err_t lyra24p_write_command ( lyra24p_t *ctx, uint8_t *command );
  • lyra24p_write_cmd_param This function writes a desired command, command value, prefix and parameter by using UART serial interface.

    err_t lyra24p_write_cmd_param ( lyra24p_t *ctx, uint8_t *command, uint8_t *cmd_val, uint8_t *prefix, uint8_t *param );
  • lyra24p_inquire_command This function writes a desired inquire command, command value and enable/disable quote by using UART serial interface.

    err_t lyra24p_inquire_command ( lyra24p_t *ctx, uint8_t *command, uint8_t *cmd_val, uint8_t en_query );

Example Description

This example demonstrates the use of LYRA 24P Click board by processing the incoming data and displaying them on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs a factory reset. In the next step, the demo app requests the LYRA module name, software version, and MAC address and sets the local device name, sets the module into VSP mode and start advertising.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    lyra24p_cfg_t lyra24p_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */

}

Application Task

Initializes the driver and performs a factory reset. In the next step, the demo app are requesting the LYRA module name, software version and MAC address and sets the local device name "LYRA 24P Click",
sets the module into VSP mode and start adverttising.

void application_task ( void ) 
{
    if ( LYRA24P_OK == lyra24p_process( &lyra24p ) ) 
    {
        lyra24p_log_app_buf( );
        lyra24p_clear_app_buf( );
        Delay_ms ( 100 );
    }
}

Note

We have used the BLE Scanner smartphone application for the test.

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.LYRA24P

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.

RTC 17 Click is a compact add-on board that accurately keeps the time of a day. This board features the RV5C387A, a CMOS real-time clock with a built-in interrupt generation function from Nisshinbo Micro Devices Inc, to perform serial transmission of time and calendar data to the MCU. The BU9873 provides information like year, month, day, weekday, hours, minutes, and seconds based on a 32.768kHz quartz crystal through an I2C serial interface to transmit time and calendar data to the MCU. It also has an alarm function that outputs an interrupt signal to the MCU when the day of the week, hour, or minute matches with the preset time.
