Click library
- Author : Nenad Filipovic
- Date : Dec 2021.
- Type : I2C type
Software Support
We provide a library for the Current Limit 7 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 Current Limit 7 Click driver.
Standard key functions :
currentlimit7_cfg_setup
Config Object Initialization function.
currentlimit7_init
Initialization function.
currentlimit7_default_cfg
Click Default Configuration function.
Example key functions :
currentlimit7_set_current_limit
Current Limit 7 set current limit function.
currentlimit7_set_resistance
Current Limit 7 set resistance function.
currentlimit7_get_fault
Current Limit 7 get fault function.
Example Description
This library contains API for the Current Limit 7 Click driver. This driver provides the functions to set the current limiting conditions in order to provide the threshold of the fault conditions.
The demo application is composed of two sections :
Application Init
Initialization of I2C module and log UART. After driver initialization, default settings turn on the device.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
Delay_ms( 100 );
log_info( &logger, " Application Task " );
log_printf( &logger, "---------------------------\r\n" );
log_printf( &logger, " Current Limit 7 Click \r\n" );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
#ifdef CURRENTLIMIT_MODE_250_mA_500_mA
log_printf( &logger, " >>> Selected mode %d \r\n", 0 );
log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );
log_printf( &logger,
" Current limit is %d mA \r\n",
limit_value_op[ 10 ] );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
#else
log_printf( &logger, " >>> Selected mode %d \r\n", 0 );
log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );
log_printf( &logger,
" Current limit is %d mA \r\n",
limit_value_op[ 0 ] );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
#endif
display_selection( );
Delay_ms( 100 );
}
Application Task
This example demonstrates the use of the Current Limit 7 Click boardâ„¢. Reading user's input from Usart Terminal and using it as an index for an array of pre-calculated values that define the current limit level. Results are being sent to the Usart Terminal, where you can track their changes.
{
static char index;
{
#ifdef CURRENTLIMIT_MODE_250_mA_500_mA
if ( ( index >= '0' ) && ( index <= '3' ) )
{
log_printf( &logger, " >>> Selected mode %d \r\n", index - 48 );
log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );
log_printf( &logger,
" Current limit is %d mA \r\n",
limit_value_op[ index - 38 ] );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
}
#else
if ( ( index >= '0' ) && ( index <= '9' ) )
{
log_printf( &logger, " >>> Selected mode %d \r\n", index - 48 );
log_printf( &logger, "- - - - - - - - - - - - - -\r\n" );
log_printf( &logger,
" Current limit is %d mA \r\n",
limit_value_op[ index - 48 ] );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
}
#endif
else
{
log_printf( &logger, " Data not in range! \r\n" );
log_printf( &logger, "---------------------------\r\n" );
display_selection( );
Delay_ms( 100 );
}
}
}
Additional Function
display_selection
This function displays selection messages. static void display_selection ( void );
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.CurrentLimit7
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.
