FT click

FT Click is a compact smart transceiver add-on board that helps you add a Free Topology (FT) interface to any host board with the mikroBUS™ socket. Leveraging FT, the most reliable and easiest-to-scale wired communications media, FT Click lets you network sensors and devices to create IoT solutions for automation and control networks that are easier to develop, integrate and install. This Click board™ supports full communication stacks for LON® and BACnet FT, as well as FTMQ (MQTT like messaging format) on board to simplify integration of BACnet, LON or custom IoT networks over twisted pair wire. FT Click is ideal for markets including smart buildings, cities, machines, agriculture, manufacturing, transportation and many more where wireless communications do not provide the required reliability and scale.

Click library

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

Software Support

We provide a library for the Ft 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 Ft Click driver.

Standard key functions :

• Config Object Initialization function.

void ft_cfg_setup ( ft_cfg_t *cfg );

• Initialization function.

FT_RETVAL ft_init ( ft_t *ctx, ft_cfg_t *cfg );

Example key functions :

• Use this function for gets current status of data

uint8_t ft_get_data_status ( ft_t *ctx );

• Use this function for read received data

uint16_t ft_get_data ( ft_t *ctx, uint8_t *data_buf );

• Use this function for send data to other module

void ft_send_package ( ft_t *ctx, uint8_t *data_buf, uint16_t len, uint8_t queue );

Examples Description

This example reads and processes data from FT clicks.

The demo application is composed of two sections :

Application Init

Initialize driver init.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ft_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.

    ft_cfg_setup( &cfg );
    FT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ft_init( &ft, &cfg );

  #ifdef DEMO_APP_RECEIVER
        log_printf( &logger, "---------------------------\r\n" );
        log_printf( &logger, "--> CURRENT MODE [ RX ] <--\r\n" );
        log_printf( &logger, "---------------------------\r\n" );
  #endif

  #ifdef DEMO_APP_TRANSMITER
        log_printf( &logger, "---------------------------\r\n" );
        log_printf( &logger, "--> CURRENT MODE [ TX ] <--\r\n" );
        log_printf( &logger, "---------------------------\r\n" );
  #endif
}
  

Application Task

RX mode : Reads and logs new receive data. TX mode : sends (MikroE) data every 1 seconds.

void application_task ( void )
{
    #ifdef DEMO_APP_RECEIVER
        ft_process(  );
        if ( ft_get_data_status( &ft ) == FT_NEW_DATA_AVAILABLE )
        {
            ft_process(  );
            rsp_data_num = ft_get_data( &ft, &rsp_data_buf[ 0 ] );
            if( rsp_data_num != 0 )
            {
                log_printf( &logger, "---------------------------\r\n" );
                log_printf( &logger, "--> READ: %s\r\n", rsp_data_buf );
                log_printf( &logger, "---------------------------\r\n" );
            }
        }
    #endif

    #ifdef DEMO_APP_TRANSMITER
        log_printf( &logger, "--------------------------\r\n" );
        log_printf( &logger, "-->  SEND MIKROE DATA  <--\r\n" );
        log_printf( &logger, "--------------------------\r\n" );
        ft_send_package( &ft, &MIKROE_DATA_BUF[ 0 ], MIKROE_DATA_BUF_LEN, MIKROE_DATA_QUEUE );
        Delay_ms( 1000 );
    #endif
} 

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.Ft

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.
