MUX 5 click

MUX 5 Click is a compact add-on board that contains a precise multiplexing solution. This board features the MAX14661, a serially controlled, dual-channel analog multiplexer from Analog Devices, allowing any of the 16 pins to be connected to either common pin simultaneously in any combination. The MAX14661 features Beyond-the-Rails™ capability that allows ±5.5V signals to be passed with any supply configuration alongside a configurable host interface that supports SPI and I2C serial communications. Both modes provide individual control of each independent switch so that any combination of switches can be applied.

Click library

  • Author : Stefan Filipovic
  • Date : Oct 2022.
  • Type : I2C/SPI type

Software Support

We provide a library for the MUX 5 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 MUX 5 Click driver.

Standard key functions :

Example key functions :

  • mux5_i2c_write_register This function writes a desired data to the selected register by using I2C serial interface.
    err_t mux5_i2c_write_register ( mux5_t *ctx, uint8_t reg, uint8_t data_in );
  • mux5_i2c_read_register This function reads data from the selected register by using I2C serial interface.
    err_t mux5_i2c_read_register ( mux5_t *ctx, uint8_t reg, uint8_t *data_out );
  • mux5_set_channels_state This function sets a desired ch_state of the channels selected with ch_mask.
    err_t mux5_set_channels_state ( mux5_t *ctx, uint16_t ch_mask, uint8_t ch_state );

Example Description

This example demonstrates the use of MUX 5 click board by mapping the common connection A and B to different channels every 5 seconds.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
mux5_cfg_t mux5_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
mux5_cfg_setup( &mux5_cfg );
MUX5_MAP_MIKROBUS( mux5_cfg, MIKROBUS_1 );
if ( MUX5_OK != mux5_init( &mux5, &mux5_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( MUX5_OK != mux5_default_cfg ( &mux5 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Maps the common connection A and B to different channels every 5 seconds, and displays the channels state on the USB UART.

void application_task ( void )
{
static uint8_t ch_num = 0;
{
log_printf ( &logger, " All channels disconnected\r\n" );
}
Delay_ms ( 1000 );
{
log_printf ( &logger, " Channel %u connected to COM_A\r\n", ( uint16_t ) ( ch_num + 1 ) );
}
{
log_printf ( &logger, " Channel %u connected to COM_B\r\n\n", ( uint16_t ) ( 16 - ch_num ) );
}
if ( ++ch_num >= 16 )
{
ch_num = 0;
}
Delay_ms ( 4000 );
}

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.MUX5

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.
