Library Description

The library covers all the necessary functions to control I2C MUX 2 click board.

Key functions:

  • void i2cmux2_hw_reset ( void ) - Hardware reset function
  • void i2cmux2_set_channel ( uint8_t channel, uint8_t ch_slave_address ) - Set channel function.
  • uint8_t i2cmux2_read_interrupt ( void ) - Read interrupt status function.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes I2C, set RST pin as output and start to write log.
  • Application Initialization - Initialization driver enables - I2C, executes call hardware reset, also write log.
  • Application Task - (code snippet) This is an example that demonstrates the use of the I2C MUX 2 Click board. In this example, we read "Who am I" ( or "State" ) register of the connected click boards to the I2C MUX 2 click. Channel 0 : 6DOF IMU 11 click [slave address: 0x0E; reg: 0x00; id val.: 0x2D], Channel 1 : Altintude click [slave address: 0x60; reg: 0x0C; id val.: 0xC4], Channel 2 : 6DOF IMU 9 click [slave address: 0x69; reg: 0x75; id val.: 0xA9], Channel 3 : RTC 10 click [slave address: 0x68; reg: 0x0F; st val.: 0x88]. All data logs write on USB UART changes every 2 sec.
void application_task ( )
{
    mikrobus_logWrite( "  CH  |   ID   |  INT " ,_LOG_LINE );
    mikrobus_logWrite( "----------------------", _LOG_LINE );
    
    // SET CHANNEL 0: 6DOF IMU 11 click
    i2cmux2_set_channel( I2CMUX2_CMD_SET_CH_0, 0x0E );
    Delay_ms( 100 );
    i2cmux2_generic_read( 0x00, &rx_data, 1 );
    mikrobus_logWrite( "   0  |  0x", _LOG_TEXT );
    display_log( I2CMUX2_CMD_SET_CH_0 );
    
    // SET CHANNEL 1: Altitude click
    i2cmux2_set_channel( I2CMUX2_CMD_SET_CH_1, 0x60 );
    Delay_ms( 100 );
    i2cmux2_generic_read( 0x0C, &rx_data, 1 );
    mikrobus_logWrite( "   1  |  0x", _LOG_TEXT );
    display_log( I2CMUX2_CMD_SET_CH_1 );
    
    // SET CHANNEL 2: 6DOF IMU 9 click
    i2cmux2_set_channel( I2CMUX2_CMD_SET_CH_2, 0x69 );
    Delay_ms( 100 );
    i2cmux2_generic_read( 0x75, &rx_data, 1 );
    mikrobus_logWrite( "   2  |  0x", _LOG_TEXT );
    display_log( I2CMUX2_CMD_SET_CH_2 );

    // SET CHANNEL 3: RTC 10 click
    i2cmux2_set_channel( I2CMUX2_CMD_SET_CH_3, 0x68 );
    Delay_ms( 100 );
    i2cmux2_generic_read( 0x0F, &rx_data, 1 );
    mikrobus_logWrite( "   3  |  0x", _LOG_TEXT );
    display_log( I2CMUX2_CMD_SET_CH_3 );

    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 2000 );
}

Additional Functions :

  • void display_log ( uint8_t sel_ch ) - Display data logs.

Other mikroE Libraries used in the example:

  • I2C
  • UART
  • Conversions

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.

Ambient 17 Click

0

Ambient 17 Click is a compact add-on board used to measure the amount of the present ambient light. This board features the TSL2572, a digital-output ambient light sensor with an I2C interface from ams AG. The TSL2572 can detect a wide range of illuminance up to 60klx and provides excellent responsivity close to the human eyes' response. It is designed to control the brightness in various applications based on ambient light availability, brightness for optimum visibility, and energy efficiency. Operation in a temperature range of -30°C to 70°C ensures stable operation under extreme conditions.

Clock Gen 4 Click

0

Clock Gen 4 Click is a compact add-on board that contains both a clock generator and a multiplier/jitter reduced clock frequency synthesizer. This board features the CS2200-CP, an analog PLL architecture comprised of a Delta-Sigma fractional-N frequency synthesizer from Cirrus Logic. This clocking device utilizes a programmable phase lock loop and allows frequency synthesis and clock generation from a stable reference clock. It generates a low-jitter PLL clock from an external crystal, supports both I²C and SPI for full software control, and also has configurable auxiliary clock output. This Click board™ is suitable for MCU clock source, or in applications like digital effects processors, digital mixing consoles, and many more.
