Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Angle4 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 Angle4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void angle4_cfg_setup ( angle4_cfg_t *cfg );

  • Initialization function.

    ANGLE4_RETVAL angle4_init ( angle4_t ctx, angle4_cfg_t cfg );

  • Click Default Configuration function.

    void angle4_default_cfg ( angle4_t *ctx );

Example key functions :

  • function used to start measurement mode.

    void angle4_start_mesuremenet ( angle4_t *ctx );

  • This function is used to retrieve Angle value depending on the given resolution.

    uint8_t angle4_get_new_angle ( angle4_t ctx, uint16_t data_out );

  • This function is used to read single byte of Data on the desired address.

    uint8_t angle4_read_byte ( angle4_t *ctx, uint8_t addr );

Examples Description

This application enables use of angular magnetic rotary sensor, which can be used as a rotary encoder.

The demo application is composed of two sections :

Application Init

Driver intialization, standard configurations and start measurement


void application_init ( void )
{
    log_cfg_t log_cfg;
    angle4_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.

    angle4_cfg_setup( &cfg );
    ANGLE4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    angle4_init( &angle4, &cfg );

    angle4_default_cfg( &angle4, ANGLE4_CCFG2_DIR_COUNTER_CLOCKWISE_ROTATION,\
                                 ANGLE4_CCFG2_ABS_RESOLUTION_14bit );
    log_printf( &logger, " --- Start measurement \r\n");

    angle4_start_mesuremenet( &angle4 );
}

Application Task

Reads Angle in degreeses and logs data to USBUART every 200 ms.


void application_task ( void )
{
    //  Task implementation.

    uint16_t angle_value;

    angle4_get_new_angle( &angle4, &angle_value );
    log_printf( &logger, " Angle : %d deg\r\n", angle_value );
    Delay_ms ( 200 );
}

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.Angle4

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.

ROTARY O Click

0

Rotary Click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 orange LEDs. It’s a perfect solution for adding a precision input knob to your design. The encoder outputs A and B signals (out of phase to each other); the knob also acts as a push-button which sends an interrupt to the target board MCU. The LED ring is controlled through SPI lines (CS, SCK, MISO, MOSI). Rotary Click can be used with either a 3.3V or 5V power supply.

Hall Current 15 Click

0

Hall Current 15 Click is a compact add-on board that provides precise AC or DC current-sensing solution. This board features the TMCS1101-Q1, a galvanically isolated Hall-effect current sensor capable of DC or AC current measurement with high accuracy, excellent linearity, and temperature stability from Texas Instruments. A low-drift, temperature-compensated signal chain provides <1.5% full-scale error across a broad operating temperature range. It also provides a reliable 600V lifetime working voltage and 3kVRMS isolation between the current path and circuitry with uni/bidirectional current sensing. Besides, the user is allowed to process the output signal in analog or digital form.

Analog Key Click is an analog keyboard on a Click board. It contains six tactile pushbuttons, used to select one of six different voltage levels. The idea behind this Click is very simple: six resistors form a voltage divider.
