Click library

  • Author : MikroE Team
  • Date : Aug 2021.
  • Type : UART type

Software Support

We provide a library for the ISO9141 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for ISO9141 Click driver.

Standard key functions :

  • iso9141_cfg_setup Config Object Initialization function.

    void iso9141_cfg_setup ( iso9141_cfg_t *cfg );
  • iso9141_init Initialization function.

    err_t iso9141_init ( iso9141_t *ctx, iso9141_cfg_t *cfg );

Example key functions :

  • iso9141_generic_write This function writes a desired number of data bytes by using UART serial interface.

    err_t iso9141_generic_write ( iso9141_t *ctx, uint8_t *data_buf, uint16_t len );
  • iso9141_generic_read This function reads a desired number of data bytes by using UART serial interface.

    err_t iso9141_generic_read ( iso9141_t *ctx, uint8_t *data_buf, uint16_t max_len );

Example Description

This example demonstrates the use of an ISO 9141 Click board by showing the communication between the two Click boards.

The demo application is composed of two sections :

Application Init

Initalizes device and makes an initial log.


void application_init ( void )
{
    iso9141_cfg_t iso9141_cfg;
    log_cfg_t logger_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( logger_cfg );
    log_init( &logger, &logger_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    iso9141_cfg_setup( &iso9141_cfg );
    ISO9141_MAP_MIKROBUS( iso9141_cfg, MIKROBUS_1 );
    if ( UART_ERROR == iso9141_init( &iso9141, &iso9141_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
#ifdef DEMO_APP_TRANSMITTER
    log_printf( &logger, " Application Mode: Transmitter\r\n" );
#else
    log_printf( &logger, " Application Mode: Receiver\r\n" );
#endif
    log_info( &logger, " Application Task " );
}

Application Task

Depending on the selected application mode, it reads all the received data or sends the desired text message once per second.


void application_task ( void )
{
#ifdef DEMO_APP_TRANSMITTER
    iso9141_generic_write( &iso9141, DEMO_TEXT_MESSAGE, strlen( DEMO_TEXT_MESSAGE ) );
    log_printf( &logger, "%s", ( char * ) DEMO_TEXT_MESSAGE );
    Delay_ms ( 1000 ); 
#else
    uint8_t rx_byte = 0;
    if ( 1 == iso9141_generic_read( &iso9141, &rx_byte, 1 ) )
    {
       log_printf( &logger, "%c", rx_byte );
    }
#endif
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.ISO9141

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. UART terminal is available in all MikroElektronika compilers.
