Expand 11 Click
Expand 11 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Application Init
Initializes the driver and performs the Click default configuration which sets the pins P0-P1 as output and P2-P3 as input.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
if ( I2C_MASTER_ERROR ==
expand11_init( &expand11, &expand11_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );

Application Task
Toggles all output pins and then reads the status of the whole port and displays the results on the USB UART approximately once per second.
{
uint8_t port_value = 0;
{
{
log_printf( &logger, " PORT STATUS \r\n" );
log_printf( &logger,
" P1: %u\r\n", ( uint16_t ) ( ( port_value &
EXPAND11_PIN_1_MASK ) >> 1 ) );
log_printf( &logger,
" P2: %u\r\n", ( uint16_t ) ( ( port_value &
EXPAND11_PIN_2_MASK ) >> 2 ) );
log_printf( &logger,
" P3: %u\r\n\n", ( uint16_t ) ( ( port_value &
EXPAND11_PIN_3_MASK ) >> 3 ) );
}
}
Delay_ms ( 1000 );

Application Output
This Click board can be interfaced and monitored in two ways:
- Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
- UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.
Additional Notes and Information
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
