Click library

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

Software Support

We provide a library for the Wifi11 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 Wifi11 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void wifi11_cfg_setup ( wifi11_cfg_t *cfg );

  • Initialization function.

    WIFI11_RETVAL wifi11_init ( wifi11_t ctx, wifi11_cfg_t cfg );

  • Device reset function.

    void wifi11_reset_device ( wifi11_t *ctx );

Example key functions :

  • Send command function.

    void wifi11_send_cmd ( wifi11_t ctx, char cmd );

  • Create TCP/UDP server function.

    void wifi11_create_tcp_udp_server ( wifi11_t *ctx, uint8_t mode, uint16_t port );

  • Connect to AP function.

    void wifi11_connect_to_ap ( wifi11_t ctx, char ssid, char *password );

Examples Description

This example reads and processes data from WiFi 11 clicks.

The demo application is composed of two sections :

Application Init

Initializes the driver and powers up the module, then connects to the desired AP and creates TCP and UDP servers on the desired local port.


void application_init ( void )
{
    log_cfg_t log_cfg;
    wifi11_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.

    app_error_flag = wifi11_rsp_check( );

    wifi11_error_check( app_error_flag );
    Delay_ms ( 500 );

    // Wifi information
    wifi11_send_cmd( &wifi11, WIFI11_CMD_ATW );
    app_error_flag = wifi11_rsp_check( );
    wifi11_error_check( app_error_flag );
    Delay_ms ( 500 );

    log_printf( &logger, "\r\n ---- TCP/IP commands ---- \r\n" );
    Delay_ms ( 500 );

    // Create TCP Server
    wifi11_create_tcp_udp_server( &wifi11, WIFI11_TCP_MODE, LOCAL_PORT );
    app_error_flag = wifi11_rsp_check( );
    wifi11_error_check( app_error_flag );
    Delay_ms ( 500 );

    // Create UDP Server
    wifi11_create_tcp_udp_server( &wifi11, WIFI11_UDP_MODE, LOCAL_PORT );
    app_error_flag = wifi11_rsp_check( );
    wifi11_error_check( app_error_flag );
    Delay_ms ( 500 );

    // Enable auto receive data mode
    wifi11_send_cmd_with_parameter( &wifi11, WIFI11_CMD_ATPK, "1" );
    app_error_flag = wifi11_rsp_check( );
    wifi11_error_check( app_error_flag );
    Delay_ms ( 500 );

    // Check network connection status
    wifi11_send_cmd( &wifi11, WIFI11_CMD_ATPI );
    app_error_flag = wifi11_rsp_check( );
    wifi11_error_check( app_error_flag );
    Delay_ms ( 500 );

    log_printf( &logger, "\r\n ---- Please connect to the TCP/UDP server listed above via" );
    log_printf( &logger, " a TCP/UDP client ---- \r\n" ); 
}

Application Task

Logs all the received data and module's responses on the USB UART.


void application_task ( void )
{
    wifi11_process( );
    wifi11_log_app_buf( );
} 

Note

In order for the example to work, user needs to set the AP SSID, password, and Local port on which the TCP and UDP servers will be created. Enter valid data for the following macros: AP_SSID, AP_PASSWORD and LOCAL_PORT.

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.Wifi11

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.
