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.


Click Library

  • Author : Stefan Filipovic
  • Date : Feb 2023.
  • Type : I2C type

Software Support

Example Description

This example demonstrates the use of Expand 11 Click board by setting and reading the port state.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Expand11

Example Key Functions

Application Init

Initializes the driver and performs the Click default configuration which sets the pins P0-P1 as output and P2-P3 as input.

void application_init ( void )
{
log_cfg_t log_cfg;
expand11_cfg_t expand11_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
expand11_cfg_setup( &expand11_cfg );
EXPAND11_MAP_MIKROBUS( expand11_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == expand11_init( &expand11, &expand11_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( EXPAND11_ERROR == expand11_default_cfg ( &expand11 ) )
{
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.

void application_task ( void )
{
static uint16_t pin_num = EXPAND11_PIN_0_MASK;
uint8_t port_value = 0;
if ( EXPAND11_OK == expand11_set_all_pins_value( &expand11, pin_num ) )
{
if ( EXPAND11_OK == expand11_read_port_value( &expand11, &port_value ) )
{
log_printf( &logger, " PORT STATUS \r\n" );
log_printf( &logger, " P0: %u\r\n", ( uint16_t ) ( port_value & EXPAND11_PIN_0_MASK ) );
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 ) );
pin_num = ( ~pin_num ) & EXPAND11_ALL_PINS_MASK;
}
}
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.
