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.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_cfg.level = LOG_LEVEL_DEBUG;
log_cfg.baud = 115200;
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
Delay_ms( 4000 );
wifi9_process( );
log_printf( &logger, "---------------------\r\n" );
log_printf( &logger, "---- System Info ----\r\n" );
log_printf( &logger, "---------------------\r\n" );
Delay_ms( 500 );
Delay_ms( 500 );
Delay_ms( 500 );
Delay_ms( 500 );
Delay_ms( 500 );
Delay_ms( 5000 );
log_printf( &logger, "--------------------------\r\n" );
log_printf( &logger, "---- Start NETCAT app ----\r\n" );
log_printf( &logger, "--------------------------\r\n" );
log_printf( &logger, "> Reads the current Station status\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> Set Station to ON status\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> Sets Station SSID and PASSWORD\r\n" );
Delay_ms( 4000 );
log_printf( &logger, "> Turn OFF - Netcat module\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> Turn ON - Netcat module\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> Sets the Netcat module as a server with port 1234\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> Excludes Netcat authentication\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> Gets the current received IP address\r\n" );
Delay_ms( 2000 );
log_printf( &logger, "> At the moment, a netcat server at port 1234 has been built\r\n" );
log_printf( &logger, "> The module is transferred to BIN-UART - for data collection\r\n" );
log_printf( &logger, "test" );
Delay_ms( 5000 );
}
Application Task
Reads the received data.
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.
