EasyPull Click is a compact add-on board designed to easily configure mikroBUS™ signals into pull-up or pull-down states, perfect for various applications. It features a universal setup with 4.7kΩ resistors to ensure stable performance across vital communication lines such as SPI, UART, I2C, and standard mikroBUS™ signals (AN, RST, PWM, INT).

We provide a library for the EasyPull 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 EasyPull Click driver.
easypull_cfg_setup
Config Object Initialization function.
void easypull_cfg_setup ( easypull_cfg_t *cfg );
easypull_init
Initialization function.
err_t easypull_init ( easypull_t *ctx, easypull_cfg_t *cfg );
easypull_get_an_pin
This function reads the state of the AN pin of EasyPull click board.
uint8_t easypull_get_an_pin ( easypull_t *ctx );
easypull_get_rst_pin
This function reads the state of the RST pin of EasyPull click board.
uint8_t easypull_get_rst_pin ( easypull_t *ctx );
easypull_get_cs_pin
This function reads the state of the CS pin of EasyPull click board.
uint8_t easypull_get_cs_pin ( easypull_t *ctx );
This example demonstrates the use of EasyPull Click boards.
The demo application is composed of two sections :
Initializes the driver and USB UART logger.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
easypull_cfg_t easypull_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.
easypull_cfg_setup( &easypull_cfg );
EASYPULL_MAP_MIKROBUS( easypull_cfg, MIKROBUS_1 );
if ( DIGITAL_OUT_UNSUPPORTED_PIN == easypull_init( &easypull, &easypull_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
It checks the state of the pins and displays their state on the USB UART.
void application_task ( void )
{
if ( EASYPULL_PIN_STATE_HIGH == easypull_get_an_pin( &easypull ) )
{
log_printf( &logger, " AN pin state: HIGH \n" );
}
else
{
log_printf( &logger, " AN pin state: LOW \n" );
}
if ( EASYPULL_PIN_STATE_HIGH == easypull_get_rst_pin( &easypull ) )
{
log_printf( &logger, " RST pin state: HIGH \n" );
}
else
{
log_printf( &logger, " RST pin state: LOW \n" );
}
if ( EASYPULL_PIN_STATE_HIGH == easypull_get_cs_pin( &easypull ) )
{
log_printf( &logger, " CS pin state: HIGH \n" );
}
else
{
log_printf( &logger, " CS pin state: LOW \n" );
}
if ( EASYPULL_PIN_STATE_HIGH == easypull_get_pwm_pin( &easypull ) )
{
log_printf( &logger, " PWM pin state: HIGH \n" );
}
else
{
log_printf( &logger, " PWM pin state: LOW \n" );
}
if ( EASYPULL_PIN_STATE_HIGH == easypull_get_int_pin( &easypull ) )
{
log_printf( &logger, " INT pin state: HIGH \n" );
}
else
{
log_printf( &logger, " INT pin state: LOW \n" );
}
log_printf( &logger, "- - - - - - - - - - - - - \r\n" );
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.

- MikroSDK.Log
- Click.EasyPull
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.
