Power MUX 2 Click
Power MUX 2 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 : Nenad Filipovic
- Date : Feb 2021.
- Type : SPI type
Software Support
Example Description
This library contains API for the Power MUX 2 Click driver. The Power MUX 2 operates in automatic switchover mode with a priority prioritizing supply 1 when present and quickly switches to supply 2 when supply 1 drops below approximately 6V.
Example Libraries
- MikroSDK.Board
- MikroSDK.Log
- Click.PowerMux2

Application Init
The application init consist of initialization of SPI driver and logger.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
if ( init_flag == SPI_MASTER_ERROR ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
#define POWERMUX2_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.

Application Task
This is an example that demonstrates the use of the Power MUX 2 Click board™. In this example, we set the resistance of the 100kΩ for the output current limit of approximately 1.23A and lower the resistance to 50kΩ, which fits the current limit of 2.25 A. Results are sent to the Usart Terminal where you can track their changes.
{
log_printf( &logger, "--------------------------\r\n" );
log_printf( &logger, " Resistance ~ 100 kOhm \r\n" );
log_printf( &logger, " Current Limit ~ 1.23 A \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, "--------------------------\r\n" );
log_printf( &logger, " Resistance ~ 50 kOhm \r\n" );
log_printf( &logger, " Current Limit ~ 2.25 A \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
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.
