Library Description

The library allows the device to be enabled or disabled and allows the mute and the unmute operation. The library also has the ability to check fault condition (over current, over temperature and too high DC offset condition).

For more details check the documentation.

Key functions:

  • void c2x30wamp_enable( uint8_t state ) - The function allows the device to be enabled or disabled.
  • void c2x30wamp_mute( uint8_t state ) - The function performs the mute or the unmute operation.
  • uint8_t c2x30wamp_checkDiagnostic( void ) - The function checks if the device in a fault condition or in a normal operation state.

Examples Description

The demo application is composed of three sections:

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization - Initializes GPIO driver and allows the device to be enabled.
  • Application Task - (code snippet) - Allows the mute operation for a period of 4 seconds, and after that allows the unmute operation for a period of 10 seconds. After that time, it checks if the overcurrent fault, over temperature fault or too high DC offset fault occurred.
    Note: When under or overvoltage condition occurs the output goes to high impedance state, but the FAULT pin will not be asserted.
     
void applicationTask()
{
 c2x30wamp_mute( _C2X30WAMP_MUTE );
 Delay_ms( 4000 );
 c2x30wamp_mute( _C2X30WAMP_UNMUTE );
 Delay_ms( 10000 );

 faultCheck = c2x30wamp_checkDiagnostic();
 if (faultCheck == 0)
 {
 mikrobus_logWrite( "Fault condition!", _LOG_LINE );
 }
}

mikroE Libraries used in the example:

  • UART

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.
