Click library

  • Author : MikroE Team
  • Date : Jun 2020.
  • Type : UART type

Software Support

We provide a library for the Dmx 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 Dmx Click driver.

Standard key functions :

  • dmx_cfg_setup Config Object Initialization function.

    void dmx_cfg_setup ( dmx_cfg_t *cfg ); 
  • dmx_init Initialization function.

    err_t dmx_init ( dmx_t *ctx, dmx_cfg_t *cfg );

Example key functions :

  • dmx_generic_write Generic write function.

    void dmx_generic_write ( dmx_t *ctx, uint8_t *data_buf, uint16_t len );
  • dmx_generic_read Generic read function.

    err_t dmx_generic_read ( dmx_t *ctx, uint8_t *data_buf, uint16_t max_len );
  • dmx_send_cmd Send command function.

    void dmx_send_cmd ( dmx_t* ctx, uint8_t *cmd );

Examples Description

This example demonstrates the use of the DMX Click board by showcasing the control for a 6-channel DMX RGB LED reflector connected to it.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;
    dmx_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.
     */

    dmx_set_auto_baud_rate( &dmx, 1 );
    Delay_ms ( 100 );

    dmx_reset( &dmx, DMX_MASTER );
    dmx_run( &dmx, DMX_CONFIG_MODE );
    Delay_ms ( 100 );

    dmx_process( );
    dmx_clear_app_buf( );

    // Clear the internal buffers

    dmx_send_cmd( &dmx, DMX_CMD_BLEN );
    dmx_rsp_check( DMX_RSP_OK );

    dmx_send_cmd( &dmx, DMX_CMD_FLEN_MASTER );
    dmx_rsp_check( DMX_RSP_OK );

    dmx_send_cmd( &dmx, DMX_CMD_ITMR );

    dmx_send_cmd( &dmx, DMX_CMD_FTMR );
    dmx_rsp_check( DMX_RSP_OK );
    dmx_log_app_buf( );

    }
}  

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.Dmx

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.
