Click library

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

Software Support

We provide a library for the Lin 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 Lin Click driver.

Standard key functions :

  • Config Object Initialization function.

    ‍void lin_cfg_setup ( lin_cfg_t *cfg );

    - Initialization function.

    ‍LIN_RETVAL lin_init ( lin_t *ctx, lin_cfg_t *cfg );

    Example key functions :

  • Generic write function.

    ‍void lin_generic_write ( lin_t *ctx, char *data_buf, uint16_t len );

    - Generic read function.

    ‍int32_t lin_generic_read ( lin_t *ctx, char *data_buf, uint16_t max_len );

  • Set enable pin state.

    ‍void lin_set_enable ( lin_t *ctx, uint8_t state );

    Examples Description

‍This example reads and processes data from LIN clicks.

The demo application is composed of two sections :

Application Init

‍Initializes the driver and makes an initial log.

void application_init ( void )
{
log_cfg_t log_cfg;
lin_cfg_t cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
lin_cfg_setup( &cfg );
LIN_MAP_MIKROBUS( cfg, MIKROBUS_1 );
lin_init( &lin, &cfg );
Delay_ms ( 100 );
lin_set_enable ( &lin, 1 );
lin_set_wake_up ( &lin, 0 );
Delay_ms ( 100 );
#ifdef DEMO_APP_RECEIVER
log_info( &logger, "---- Receiver mode ----" );
#endif
#ifdef DEMO_APP_TRANSMITTER
log_info( &logger, "---- Transmitter mode ----" );
#endif
}
LIN_MAP_MIKROBUS
#define LIN_MAP_MIKROBUS(cfg, mikrobus)
Definition lin.h:66
lin_set_wake_up
void lin_set_wake_up(lin_t *ctx, uint8_t state)
Set wake up pin state.
lin_cfg_setup
void lin_cfg_setup(lin_cfg_t *cfg)
Config Object Initialization function.
lin_set_enable
void lin_set_enable(lin_t *ctx, uint8_t state)
Set enable pin state.
lin_init
LIN_RETVAL lin_init(lin_t *ctx, lin_cfg_t *cfg)
Initialization function.
application_init
void application_init(void)
Definition main.c:71
lin_cfg_t
Click configuration structure definition.
Definition lin.h:119

Application Task

‍Depending on the selected mode, it reads all the received data or sends the desired message every 2 seconds.

void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
lin_process( );
#endif
#ifdef DEMO_APP_TRANSMITTER
lin_generic_write( &lin, TEXT_TO_SEND, strlen( TEXT_TO_SEND ) );
log_info( &logger, "---- Data sent ----" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
#endif
}
lin_generic_write
void lin_generic_write(lin_t *ctx, char *data_buf, uint16_t len)
Generic write function.
application_task
void application_task(void)
Definition main.c:107
TEXT_TO_SEND
#define TEXT_TO_SEND
Definition main.c:36

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.Lin

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.
