Click library

  • Author : MikroE Team
  • Date : jun 2020.
  • Type : UART GSM/IOT type

Software Support

We provide a library for the Ble3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Ble3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ble3_cfg_setup ( ble3_cfg_t *cfg );

  • Initialization function.

    BLE3_RETVAL ble3_init ( ble3_t ctx, ble3_cfg_t cfg );

Example key functions :

  • Generic read function.

    int32_t ble3_generic_read ( ble3_t ctx, char data_buf, uint16_t max_len );

  • Generic write function.

    void ble3_generic_write ( ble3_t ctx, char data_buf, uint16_t len );

Examples Description

This example reads and processes data from BLE 3 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver and wake-up module.


void application_init ( void )
{
    log_cfg_t log_cfg;
    ble3_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 ----" );
    //  Click initialization.

    ble3_cfg_setup( &cfg );
    BLE3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ble3_init( &ble3, &cfg );

    log_printf( &logger, "Configuring the module...\n" );
    Delay_1sec( );

    do {
        ble3_generic_write( &ble3, AT, (uint16_t) strlen( AT ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    do {
        ble3_generic_write( &ble3, ATE1, (uint16_t) strlen( ATE1 ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    do {
        ble3_generic_write( &ble3, AT_UBTLN, (uint16_t) strlen( AT_UBTLN ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    do {
        ble3_generic_write( &ble3, AT_UBTDM, (uint16_t) strlen( AT_UBTDM ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    do {
        ble3_generic_write( &ble3, AT_UBTCM, (uint16_t) strlen( AT_UBTCM ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    do {
        ble3_generic_write( &ble3, AT_UBTPM, (uint16_t) strlen( AT_UBTPM ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    do {
        ble3_generic_write( &ble3, ATO1, (uint16_t) strlen( ATO1 ) );
        Delay_100ms( );
    }
    while(ble3_process(  ) != 1);

    data_mode = 1;
    log_printf( &logger, "The module has been configured.\n" );
}

Application Task

Reads the received data.


void application_task ( void )
{
    ble3_process(  );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ble3

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.

Buck click

1

BUCK click is a buck switching regulator that accepts a wide input voltage range of up to 40V and steps it down to 3.3V or 5V. The click carries the LT3976 40V, 5A, 2MHz step-down switching regulator with 3.3µA quiescent current.

Brushless 4 click

5

Brushless 4 click is a 3 phase sensorless BLDC motor driver, which features a 180° sinusoidal drive, providing high efficiency and low acoustic noise. This type of drivers inherently provides higher torque in general, compared to classical 120° BLDC motor drivers.

RS Transceiver Click

0

RS Transceiver is a compact add-on board that offers an interface between the TTL level UART and RS-232/RS-422/RS-485 communication buses. This board features the XR34350, an RS-232/RS-422/RS-485 serial transceiver with internal termination and wide output swing from MaxLinear. Integrated cable termination and four configuration modes allow all three protocols to be used interchangeably over a single cable over the DE-9 connector. All transmitter outputs and receiver inputs feature robust ESD protection and HBM up to ±15kV.
