Click library

  • Author : Luka Filipovic

  • Type : ADC type

Software Support

We provide a library for the Ambient7 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 Ambient7 Click driver.

Standard key functions :

Example key functions :

  • ambient7_read_an_pin_value This function reads results of AD conversion of the AN pin.
    err_t ambient7_read_an_pin_value ( ambient7_t *ctx, uint16_t *data_out );
  • ambient7_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.
    err_t ambient7_read_an_pin_voltage ( ambient7_t *ctx, float *data_out );

Examples Description

Reads the AN pin voltage.

The demo application is composed of two sections :

Application Init

Initializes ADC and LOG for logging data.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
AMBIENT7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ambient7_init( &ambient7, &cfg );
log_info( &logger, " Application Task " );
}

Application Task

Reads the AN pin voltage and displays the results on the USB UART once per second.

void application_task ( void )
{
float voltage = 0;
if ( AMBIENT7_OK == ambient7_read_an_pin_voltage ( &ambient7, &voltage ) )
{
log_printf( &logger, " AN Voltage : %.3f[V]\r\n\n", voltage );
Delay_ms ( 1000 );
}
}

Note

Illuminance range [ EV ] - from 0.01 [ lx ] to 10k [ lx ]

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.Ambient7

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.
