Click library

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

Software Support

We provide a library for the Ambient 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 Ambient Click driver.

Standard key functions :

  • ambient_cfg_setup Config Object Initialization function.

    void ambient_cfg_setup ( ambient_cfg_t *cfg ); 
  • ambient_init Initialization function.

    err_t ambient_init ( ambient_t *ctx, ambient_cfg_t *cfg );

Example key functions :

  • ambient_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

    err_t ambient_read_an_pin_voltage ( ambient_t *ctx, float *data_out );
  • ambient_get_light_intensity Calculates the light intensity from analog voltage measurement of the Melexis MLX75305 IC on Ambient Click board.

    uint16_t ambient_get_light_intensity ( ambient_t *ctx );

Example Description

This application turns light intensity into voltage.

The demo application is composed of two sections :

Application Init

Initialization driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;
    ambient_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.
    ambient_cfg_setup( &cfg );
    AMBIENT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ambient_init( &ambient, &cfg );

    log_info( &logger, " Application Task " );
}

Application Task

This is an example which demonstrates the use of Ambient Click board. Ambient Click reads ADC voltage once per second and converts it to light intensity [ uW/cm2 ]. Results are being sent to the USB UART where you can track their changes.


void application_task ( void )
{
    uint16_t light_intensity = ambient_get_light_intensity( &ambient );
    log_printf( &logger, " Light Intensity: %u uW/cm2\r\n\n", light_intensity );
    Delay_ms ( 1000 );
}  

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.Ambient

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.

LSM303AGR Click

0

LSM303AGR Click is a magnetometer and accelerometer device, capable of sensing both the magnetic and gravitational field along three orthogonal axes. It uses the LSM303AGR from STMicroelectronics, an integrated MEMS IC with plenty of features that allow accurate and reliable sensing, even in presence of foreign objects made of iron and similar materials that exhibit ferromagnetic behavior. An extensive interrupt engine can be programmed to generate an interrupt signal for free-falling events, motion detection, and magnetic field detection. The Click board™ can sense the magnetic field in the range of ±50 G (gauss) and ±2g, ±4g, ±8g, and ±16g selectable ranges for the full-scale acceleration detection (gravity force).
