EasyPull Click

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).

Software Support

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.

Library Description

This library contains API for EasyPull Click driver.

Example Description

This example demonstrates the use of EasyPull Click boards.

The demo application is composed of two sections :

Application Init

Initializes the driver and USB UART logger.

void application_init ( void )
{
log_cfg_t log_cfg;
easypull_cfg_t easypull_cfg;
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 " );
}

Application Task

It checks the state of the pins and displays their state on the USB UART.

void application_task ( void )
{
{
log_printf( &logger, " AN pin state: HIGH \n" );
}
else
{
log_printf( &logger, " AN pin state: LOW \n" );
}
{
log_printf( &logger, " RST pin state: HIGH \n" );
}
else
{
log_printf( &logger, " RST pin state: LOW \n" );
}
{
log_printf( &logger, " CS pin state: HIGH \n" );
}
else
{
log_printf( &logger, " CS pin state: LOW \n" );
}
{
log_printf( &logger, " PWM pin state: HIGH \n" );
}
else
{
log_printf( &logger, " PWM pin state: LOW \n" );
}
{
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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • 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.
