Click library

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

Software Support

We provide a library for the Wifi9 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 Wifi9 Click driver.

Standard key functions :

• Config Object Initialization function.

void wifi9_cfg_setup ( wifi9_cfg_t *cfg );

• Initialization function.

WIFI9_RETVAL wifi9_init ( wifi9_t *ctx, wifi9_cfg_t *cfg );

• Click Default Configuration function.

void wifi9_default_cfg ( wifi9_t *ctx );

Example key functions :

• Switch to a command or binary uart

void wifi9_select_uart ( wifi9_t *ctx, uint8_t uart_select );

• Module power up.

void wifi9_module_power ( wifi9_t *ctx );

• Send Command function.

void wifi9_send_command ( wifi9_t *ctx, char *command );

Examples Description

This example reads and processes data from Wifi 9 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;
    wifi9_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.

}
  

Application Task

Reads the received data.

void application_task ( void )
{
    wifi9_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.Wifi9

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.
