Click library

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

Software Support

We provide a library for the UartMux 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 UartMux Click driver.

Standard key functions :

  • Config Object Initialization function.

    void uartmux_cfg_setup ( uartmux_cfg_t *cfg );

  • Initialization function.

    UARTMUX_RETVAL uartmux_init ( uartmux_t ctx, uartmux_cfg_t cfg );

Example key functions :

  • Send command.

    void uartmux_send_command ( uartmux_t ctx, char command, uartmux_channel_t *channel );

  • Set INT pin

    void uartmux_set_inhibit_communication ( uartmux_t *ctx, uint8_t state );

  • Choose channel

    void uartmux_choose_channel ( uartmux_t ctx, uartmux_channel_t channel );

Examples Description

This example reads and processes data from UART Mux clicks.

The demo application is composed of two sections :

Application Init

Initializes driver.


void application_init ( void )
{
    log_cfg_t log_cfg;
    uartmux_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.

    uartmux_cfg_setup( &cfg );
    UARTMUX_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    uartmux_init( &uartmux, &cfg );

    uartmux_set_inhibit_communication( &uartmux, UARTMUX_PIN_STATE_LOW );
}

Application Task

Reads the received data.


void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
    uartmux_process( );
#endif

#ifdef DEMO_APP_TRANSMITER
    uartmux_process( );

    channel.state_a = UARTMUX_STATE_A_CHANNEL_1;
    channel.state_b = UARTMUX_STATE_B_CHANNEL_1;

    if ( send_data_cnt == 2 )
    {
        uartmux_send_command( &uartmux, TEXT_TO_SEND, &channel );
        uartmux_process( );
        send_data_cnt = 0;
    }
    else
    {
        send_data_cnt++;
    }
#endif
} 

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.UartMux

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.

LR IoT Click

0

LR IoT Click is a compact add-on board that contains a long-range LoRa transceiver. This board features Semtech Corporation’s LR1110, an ultra-low power platform integrating a LoRa® transceiver, multi-constellation GNSS, and passive WiFi AP MAC address scanner. Alongside its sub-GHz capabilities, the LR1110 also has a multi-band front-end capable of receiving 802.11b/g/n WiFi Access Point MAC addresses and GNSS (GPS, BeiDou, geostationary) satellite raw data befitting geo-positioning purposes. The acquired information is then transmitted using an LPWAN network to a geolocation server, which analyzes it and correlates the position with data from a geolocation database, enabling a unique balance between low power and performance.

UNI Hall click

5

The unipolar Hall effect sensor on UNI HALL click™ is sensitive to north pole magnetic fields—when exposed to such a field, it outputs a LOW logic level. Othewise the output is a HIGH logic level. In its simplest application, UNI HALL click™ can be employed as part of a long lasting contactless proximity switch.
