Click library

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

Software Support

We provide a library for the OptoEncoder2 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 OptoEncoder2 Click driver.

Standard key functions :

  • optoencoder2_cfg_setup Config Object Initialization function.

    void optoencoder2_cfg_setup ( optoencoder2_cfg_t *cfg ); 
  • optoencoder2_init Initialization function.

    err_t optoencoder2_init ( optoencoder2_t *ctx, optoencoder2_cfg_t *cfg );

Example key functions :

  • optoencoder2_pwm_get Getting PWM pin state

    uint8_t optoencoder2_pwm_get ( optoencoder2_t *ctx );
  • optoencoder2_int_get Getting INT pin state

    uint8_t optoencoder2_int_get ( optoencoder2_t *ctx );
  • optoencoder2_get_position Getting encoder position

    int32_t optoencoder2_get_position ( optoencoder2_t *ctx );

Examples Description

This application is used to encode motion or rotation.

The demo application is composed of two sections :

Application Init

Initializes GPIO driver and resets encoder counter to 0 (zero).


void application_init ( void )
{
    log_cfg_t log_cfg;
    optoencoder2_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.
    optoencoder2_cfg_setup( &cfg );
    OPTOENCODER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    optoencoder2_init( &optoencoder2, &cfg );

    optoencoder2_zero_counter( &optoencoder2 );
}

Application Task

If motion is detected - encoder increments or decrements position on each rising edge on Channel A (INT pin) and logs encoder position.


void application_task ( )
{
    int32_t encoder_position = 0;
    uint8_t stop_flag = 0;

    stop_flag = optoencoder2_isr( &optoencoder2, 100 );
    encoder_position = optoencoder2_get_position( &optoencoder2 );

    if ( stop_flag == 0 )
    {
        log_printf( &logger, "Position: %ld \r\n", encoder_position );
    }
}  

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.OptoEncoder2

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.

Grid-EYE 2 Click is a compact add-on board designed for thermal imaging and motion detection applications. This board features the AMG883543, an infrared array sensor from Panasonic with a 90° viewing angle and an 8x8 pixel matrix that measures temperatures from 0°C to 80°C with a resolution of 0.25°C. The sensor can detect objects up to 5 meters away and outputs temperature data via a digital interface. The board also supports the Click Snap feature, allowing the main sensor area to be detached for flexible positioning.

2x2 RGB Click is a compact add-on board that contains a matrix of 4 “intelligent” RGB elements, forming a 2x2 display screen. This board features the KTD2052A, a 12-channel RGB LED driver from Kinetic Technologies. It is a fully programmable current regulator for up to four RGB LEDs (12 LEDs in total). The LED matrix consists of four LRTB GFTG, a 6-lead in-line MULTILEDs, from ams OSRAM. The LEDs have a 120-degree viewing angle.

Rotary R click

5

Rotary R click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 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.
