Library Description

The library covers all the necessary functions to control I2C MUX 4 Click board. A library performs the communication with the TCA9543A Low Voltage 2-Channel I2C Bus Switch via I2C interface.

Key functions:

  • void i2cmux4_power_on ( uint8_t enable ) - Power On function.
  • void i2cmux4_set_channel ( uint8_t sel_ch, uint8_t ch_slave_addr ) - Set channel function.
  • uint8_t i2cmux4_check_int ( void ) - Check interrupt function.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes I2C, set RST pin as output, INT pin as input and start to write log.
  • Application Initialization - Initialization driver enables - I2C, executes call power On and hardware reset, also write log.
  • Application Task - (code snippet) This is an example that demonstrates the use of the I2C MUX 4 Click board. In this example, we read "Who am I" ( or "State" ) register of the connected click boards to the I2C MUX 4 click. Channel 0 : 6DOF IMU 12 click [slave address: 0x0E; reg: 0x00; id val.: 0x24], Channel 1 : RTC 10 click [slave address: 0x68; reg: 0x0F; st val.: 0x88]. All data logs write on USB UART changes approximately every 2 sec.
void application_task ( )
{
    // CH 0 - 6DOF IMU 12 click
    i2cmux4_set_channel( I2CMUX4_SEL_CH_0, 0x68 );
    Delay_ms( 100 );

    i2cmux4_rmt_read_bytes( 0x00, &rx_data, 1 );
    Delay_ms( 100 );

    ByteToHex( rx_data, log_text );
    mikrobus_logWrite( "    6DOF IMU 12 click  ", _LOG_LINE );
    mikrobus_logWrite( "- - - - - - - - - - - -", _LOG_LINE );
    mikrobus_logWrite( "       ID = 0x", _LOG_TEXT );
    mikrobus_logWrite( log_text, _LOG_LINE );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    Delay_ms( 1000 );
    
    
    // CH 1 - RTC 10 click
    i2cmux4_set_channel( I2CMUX4_SEL_CH_1, 0x68 );
    Delay_ms( 100 );

    i2cmux4_rmt_read_bytes( 0x0F, &rx_data, 1 );
    Delay_ms( 100 );

    ByteToHex( rx_data, log_text );
    mikrobus_logWrite( "      RTC 10 click     ", _LOG_LINE );
    mikrobus_logWrite( "- - - - - - - - - - - -", _LOG_LINE );
    mikrobus_logWrite( "       ID = 0x", _LOG_TEXT );
    mikrobus_logWrite( log_text, _LOG_LINE );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
