Expand 10 Click is a compact add-on board that contains a multi-port I/O expander. This board features the PCAL6524, a 24-bit general-purpose I/O expander providing remote I/O expansion for most MCU’s families via the Fast-mode Plus I2C-serial interface from NXP Semiconductors.
We provide a library for the Expand10 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Expand10 Click driver.
expand10_cfg_setup
Config Object Initialization function.
void expand10_cfg_setup ( expand10_cfg_t *cfg );
expand10_init
Initialization function.
err_t expand10_init ( expand10_t *ctx, expand10_cfg_t *cfg );
expand10_default_cfg
Click Default Configuration function.
err_t expand10_default_cfg ( expand10_t *ctx );
expand10_set_pin_direction
This function sets the direction of the selected pins.
err_t expand10_set_pin_direction ( expand10_t *ctx, uint8_t direction, uint8_t port, uint8_t pin_mask );
expand10_set_pin_value
This function sets the value of the selected pins.
err_t expand10_set_pin_value ( expand10_t *ctx, uint8_t port, uint8_t clr_mask, uint8_t set_mask );
expand10_read_port_value
This function reads the value of the selected port input pins.
err_t expand10_read_port_value ( expand10_t *ctx, uint8_t port, uint8_t *data_out );
This example demonstrates the use of Expand 10 Click board.
The demo application is composed of two sections :
Initializes the driver and performs the Click default configuration which sets the first two ports as output and the third port as input with pull-down enabled.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
expand10_cfg_t expand10_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
expand10_cfg_setup( &expand10_cfg );
EXPAND10_MAP_MIKROBUS( expand10_cfg, MIKROBUS_1 );
err_t init_flag = expand10_init( &expand10, &expand10_cfg );
if ( I2C_MASTER_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
init_flag = expand10_default_cfg ( &expand10 );
if ( EXPAND10_ERROR == init_flag )
{
log_error( &logger, " Default Config Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
Sets the pins of the first two ports and then reads and displays the status of all ports on the USB UART approximately once per second.
void application_task ( void )
{
uint8_t port_value = 0;
for ( uint16_t pin_num = EXPAND10_PIN_0_MASK; pin_num <= EXPAND10_PIN_7_MASK; pin_num <<= 1 )
{
expand10_set_all_pins_value( &expand10, pin_num );
expand10_read_port_value( &expand10, EXPAND10_PORT_0, &port_value );
log_printf( &logger, " Status P0 (output): 0x%.2X\r\n", ( uint16_t ) port_value );
expand10_read_port_value( &expand10, EXPAND10_PORT_1, &port_value );
log_printf( &logger, " Status P1 (output): 0x%.2X\r\n", ( uint16_t ) port_value );
expand10_read_port_value( &expand10, EXPAND10_PORT_2, &port_value );
log_printf( &logger, " Status P2 (input) : 0x%.2X\r\n\r\n", ( uint16_t ) port_value );
Delay_ms ( 1000 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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. UART terminal is available in all MikroElektronika compilers.
