Click library

  • Author : MikroE Team
  • Date : Feb 2020.
  • Type : I2C type

Software Support

We provide a library for the LedDriver7 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for LedDriver7 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void leddriver7_cfg_setup ( leddriver7_cfg_t *cfg );

  • Initialization function.

    LEDDRIVER7_RETVAL leddriver7_init ( leddriver7_t ctx, leddriver7_cfg_t cfg );

Example key functions :

  • Generic write function.

    void leddriver7_generic_write ( leddriver7_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

  • Generic read function.

    void leddriver7_generic_read ( leddriver7_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

Examples Description

This application is portable lighting and rechargeable flashlights.

The demo application is composed of two sections :

Application Init

Initalizes I2C driver and writes an initial log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    leddriver7_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    leddriver7_cfg_setup( &cfg );
    LEDDRIVER7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    leddriver7_init( &leddriver7, &cfg );

    Delay_ms ( 100 );
    log_printf( &logger, "-------------------- \r\n" );
    log_printf( &logger, " LED Driver 7 Click  \r\n" );
    log_printf( &logger, "-------------------- \r\n" );
}

Application Task

This example demonstrates the use of LED Driver 7 Click board, by cycling wiper positions of AD5171 Digital Potentiometer.


void application_task ( void )
{
    uint8_t n_pos = 0;
    uint8_t pos_num = 64;

    for ( n_pos = 12; n_pos < pos_num; n_pos++ )
    {
        leddriver7_generic_write( &leddriver7, LEDDRIVER7_NORM_OP_MODE, &n_pos, 1 );
        log_printf( &logger, "Position : %d \r\n", n_pos );
        Delay_ms ( 500 );
    }
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.LedDriver7

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.

Smart DOF 5 Click

0

Smart DOF 5 Click is a compact add-on board designed for precise motion and orientation detection in automotive applications. This board features the ASM330LHHXG1, a high-accuracy 6-axis inertial measurement unit (IMU) from STMicroelectronics. It features a 3-axis accelerometer and a 3-axis gyroscope and supports dual operating modes (high-performance and low-power) with flexible communication options through SPI or I2C interfaces. Additionally, it includes the Click Snap format, enabling the autonomous use of the Snap section and integration of external sensors via the I2C Master interface.

Accel 20 Click

0

Accel 20 Click is a compact add-on board that contains an acceleration sensor. This board features the KX134-1211, a digital output 3-axis accelerometer optimized for machine condition monitoring from Rohm Semiconductor. It allows selectable full-scale acceleration measurements in ranges of ±8g, ±16g, ±32g, or ±64g in three axes with a configurable host interface that supports both SPI and I2C serial communication. It also features an Advanced Data Path (ADP) technology which allows noise filtering and sensor signal processing, usually carried out by the MCU, to be performed by the accelerometer. They contribute to reducing MCU load and power consumption together with improved application performance.
