Library Description

The library carries generic command parser adopted for AT command based modules. The library contains an example for basic initialization of the actuator and sensor demo example.

Key functions:

• void g2c_cmdSingle( char *pCmd ) - Sends provided command to the module
• void g2c_coreInit( T_g2c_handler defaultHdl, uint32_t defaultWdog ) - Core Initialization
• void g2c_modulePower( bool powerState ) - Turn ON or OFF the module.
• void g2c_process() - AT Engine State Machine

Examples description

The application is composed of the three sections :

• System Initialization - Initializes all necessary GPIO pins, UART used for the communication with G2C click.
• Application Initialization - Initializes driver, power on module. Commands are sent to prepare the module for communication with the g2c.
• Application Task - running in parallel core state machine and checks for the URC message from Click G2C.

Note: Example demonstrates the measurement of inductance change depending on the linear motion of the metal object. Induction of the linear metal position depends on the type of metal and the configuration.

void applicationTask()
{
    char demoBuffer[ 50 ];
    
// CORE STATE MACHINE
    g2c_process();

// SENSOR - Remove if not used
   if( taskTime > 1500 )
   {
    taskTime = 0;        
    g2c_packCmd( &_AT_DSET[0], &g2c_sensorRef[0], &demoBuffer[0]);
    g2c_cmdSingle( &_AT_PUB[0] );
   }

// ACTUATOR - Remove if not used
   if(state == 1 && oldstate == 0)
   {
   // User code if the swithc is set to 1
    oldstate = 1;
   }

   if(state == 0 && oldstate == 1)
   {
   // User code if the swithc is set to 0
    oldstate = 0;
   }
}

Other mikroE Libraries used in the example:

• UART
• String
• Conversion

Additional notes and information

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.
