Click library

  • Author : MikroE Team
  • Date : Dec 2020.
  • Type : UART type

Software Support

We provide a library for the BLE9 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 Ble9 Click driver.

Standard key functions :

  • ble9_cfg_setup function initializes Click configuration structure to initial values.

    void ble9_cfg_setup ( ble9_cfg_t *cfg );
  • ble9_init function initializes all necessary peripherals.

    err_t ble9_init ( ble9_t *ctx, ble9_cfg_t *cfg );

Example key functions :

  • ble9_adv_create_id function creates adequate ID.

    err_t ble9_adv_create_id ( ble9_t *ctx );
  • ble9_adv_start function starts advertising.

    err_t ble9_adv_start ( ble9_t *ctx, ble9_adv_mode_discoverable_t discover, ble9_adv_mode_connectable_t connect );

Examples Description

This example demonstrates the use of BLE 9 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 the Click default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;
    ble9_cfg_t cfg;

    /** 
     * 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.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
    Delay_ms ( 100 );

    // Click initialization.
    ble9_cfg_setup( &cfg );
    BLE9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ble9_init( &ble9, &cfg );
    Delay_ms ( 1000 );

    // Clear app buffer
    ble9_process ( &ble9 );
    ble9_clear_app_buf( );
    Delay_ms ( 100 );

    if ( BLE9_OK == ble9_sys_get_version ( &ble9 ) )
    {
        log_printf( &logger, "--- System Version ---\r\n" );
        log_printf( &logger, " Major: 0x%.4X\r\n", ble9.ble9_version.version_major );
        log_printf( &logger, " Minor: 0x%.4X\r\n", ble9.ble9_version.version_minor );
        log_printf( &logger, " Patch: 0x%.4X\r\n", ble9.ble9_version.version_patch );
        log_printf( &logger, " Build: 0x%.4X\r\n", ble9.ble9_version.version_build );
        log_printf( &logger, " Bootloader: 0x%.8LX\r\n", ble9.ble9_version.version_bootloader );
        log_printf( &logger, " Hash: 0x%.8LX\r\n", ble9.ble9_version.version_hash );
        log_printf( &logger, "------------------------\r\n" );
    }

    log_printf( &logger, "Creating advertising point...\r\n" );
    Delay_ms ( 100 );
    ble9_adv_create_id ( &ble9 );

    log_printf( &logger, "Starting module advertising...\r\n" );
    Delay_ms ( 100 );
    ble9_adv_start ( &ble9, BLE9_ADVERTISER_MODE_DISCOVERABLE_GENERAL, 
                     BLE9_ADVERTISER_MODE_CONNECTABLE_SCANNABLE );

    log_printf( &logger, "The module has been configured.\r\n" );
    Delay_ms ( 100 );
}

Application Task

Reads and processes all incoming data and displays them on the USB UART.


void application_task ( void )
{
    ble9_process ( &ble9 );
    if ( app_buf_len > 0 ) 
    {
        for ( uint16_t cnt = 0; cnt < app_buf_len; cnt++ )
        {
            log_printf( &logger, "%.2X ", ( uint16_t ) app_buf[ cnt ] );
        }
        ble9_clear_app_buf( );
    }
}

Note

For more information on the chip itself and the firmware on it,
please visit the following page:
    [1] https://docs.silabs.com/bluetooth/3.1
        - Take into condideration that the library itself
          is designed to work with GSDK version 3.1.0
          If you wish to use a different version of firmware,
          take into consideration that some functions might not work.

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.Ble9

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.

Joystick 3 Click is a compact add-on board that can fulfill your directional analog input needs. This board features 2765, a high-quality mini 2-axis analog output thumbstick from Adafruit Industries. This small joystick is a 'self-centering' analog-type with a black rocker cap similar to the PSP joysticks. It comprises two 10kΩ potentiometers, one for up/down and another for left/right direction. Knowing that this joystick represents an analog type, it connects with mikroBUS™ through the SPI interface through the MCP3204 12-bit A/D converter.
